Using mathematical inquiry to make mathematics meaningful

At the moment I’m involved in a project with the Sydney Metro (Transport for NSW), currently the largest infrastructure project in Australia. When complete, the Sydney Metro project is going to change the way many Sydney residents work, live and socialise. My involvement with this project has required me to design, deliver and research the effectiveness of a professional learning program. In this program, teachers from all stages of schooling and a range of curriculum areas learn about using inquiry based learning and then design, implement and evaluate units of work that use the Sydney Metro project as the stimulus for inquiry.  So what’s that got to do with engaging maths? My work in this project has confirmed what I’ve always believed – contextualising learning makes mathematics (and other disciplines, of course) more meaningful, purposeful and relevant for students. It shifts the traditional approach of ‘just in case’ learning to ‘just in time learning’.

Using contexts from student’s lives, such as Sydney Metro, makes mathematics come alive. For example, some of the students participating in the inquiry based units are looking at the social implications of having a rail station constructed in their community where there previously wasn’t one. This inquiry provides a purpose for designing survey questions, collecting, representing and analysing data that has meaning and purpose. Others are looking at the engineering aspects of the project relating to the tunnelling that is currently underway. Some are working on design aspects relating to the trains themselves or the stations and some are looking at mapping – planning future metro lines, or timing (the system won’t have a timetable).

The possibilities are endless, but for these units of work (or indeed, any inquiry based unit of work) to be successful, the teachers planning them have to consider carefully the potential directions that students will take their inquiry if the units are to be true inquiry based learning that is driven by students’ interests. This requires a strong knowledge of curriculum and a willingness to hand over some control of the learning to the students. It may even involve the introduction of content beyond the students’ current grade.
Another consideration when planning inquiry units is the inclusion of other aspects of our curriculum, beyond content. For example, in mathematics we have the Proficiencies (Working Mathematically in NSW) that represent the processes of mathematics. It’s impossible to conduct inquiry based learning without these processes and inquiry learning is a perfect opportunity to develop, refine and show evidence of these processes. Then we have the General Capabilities. Again, inquiry based learning provides an opportunity to access mathematics while accessing these capabilities, enhancing the relevance of the learning.

Where do you find resources for inquiry? Take a look around at what is happening in your community, in the media, or simply the things that your students are interested in. Consider how those things could spark curiosity in your students (or how you could promote that curiosity within  your students). Model how to ask good questions (students need to know how to do this – it doesn’t always come naturally). Be prepared for it to get messy, search for resources that the students might need or help them find resources. Be prepared to teach a range of mathematical concepts as the need arises.

I’ll you with an example of a resource that I believe would be a great stimulus for inquiry – take a look, at let me know what you think! Every Drop Counts

Tips for beginning primary teachers: What’s in your maths toolbox?

If you’re an early career teacher, chances are you spend lots of your spare time looking for good maths resources. Some of you may have your own class, while others are beginning their careers as a relief teacher, having to move from one class to another, and often between different schools. Many teachers who are starting out have to build their toolbox of resources from nothing. Where do you begin? How can you develop a bank of activities that suits lots of different levels and abilities, and engages children of diverse abilities?

One of the first things I would recommend would be to invest in a small range of materials that allow you to implement some simple tasks that could then be expanded into interesting and worthwhile mathematical investigations. For example, if you purchase around ten sets of playing cards (go to a cheap two dollar store), you could learn a few basic games (Snap, Making 10, Playing with Place Value – see my book Engaging Maths: Exploring Number) that could then be differentiated according to the students you are teaching. A simple game of Making 10 could be used from Grade 1 all the way to Grade 6 by simply changing the rules.

Other materials that are a ‘must have’ for beginning teachers are dice and dominoes. There are many simple investigations that could lead from simple explorations with these materials. For example, use the dice to explore probability or play a game of Greedy Pig. Play a traditional game of dominoes before adding a twist to it, or simply ask students to sort the dominoes (students have to select their own criteria for sorting)– an interesting way to gain insight into students’ mathematical thinking and a great opportunity for using mathematical language. Once students have sorted the dominoes conduct an ‘art gallery tour’ and ask other students to see if they can work out how others have sorted out their dominoes. Photograph the sorting and display then on an Interactive Whiteboard for a whole class discussion and reflection…the list goes on!

Another ‘must have’ for beginning teachers is a bank of good quality resource books. Don’t fall into the trap of purchasing Black Line Masters or books full of worksheets to photocopy. You don’t want your students to be disengaged! Books such as my Engaging Maths series (http://engagingmaths.co/teaching-resources/books/ ), or any of Paul Swan’s books or resources (http://www.drpaulswan.com.au/resources/) are a great place to start. Explore some of the excellent free resources available online such as http://nrich.maths.org/teacher-primary and http://illuminations.nctm.org/, but do be aware that some resources produced outside of Australia will need to adapted for the Australian Curriculum: Mathematics.

In my research on student engagement, I found that students would remember what they would recall as a ‘good’ mathematics lesson for a very long period of time. In fact, some of the students in my PhD study talked about a ‘good’ mathematics lesson two years after it had taken place. Whether you are lucky enough to have your own class or have to begin your career as a relief teacher moving from class to class, you can make an impact on the students in your care and the way the view mathematics by being prepared with your ‘toolbox’ of engaging and worthwhile activities.

 

More tips for teachers: Essential materials for every mathematics classroom

What hands-on materials and resources do you have in your mathematics classroom?  Concrete materials, coupled with good teaching practice and strong teacher content knowledge, provide opportunities for learners to construct rich understandings of mathematical concepts. In addition, allowing opportunities for children to physically engage with materials can be much more meaningful than working only with visual or even digital representations, particularly when learners are still in the concrete phase of their learning about specific concepts. For example, if you’re teaching concepts relating to 3-dimensional space, it makes sense that it is better for children to be able to manipulate real objects in order to explore their properties and relate their learning to real-life, as opposed to exploring objects through graphical representations only. Concrete materials also promote the use of mathematical language, reasoning, and problem solving.

I’m often asked about the essential resources required for primary mathematics classrooms. There are quite a few, but if you have a limited budget or storage space, there are some resources that are what I would consider to be essential, regardless of the year level that you are teaching. My advice would be to invest in materials that are flexible and able to be used in a variety of ways, perhaps in conjunction with other materials. Also consider collecting things that are not necessarily intended as educational resources but may have some mathematical value, such as collections of things (keys, lids, plastic containers, etc.) for activities that require sorting and classifying. Here is a list of basics that can be purchased from educational resources suppliers (some of the items can also be sources at normal retail and/or discount stores):

  • Counters
  • Dice (as well as the standard six sided dice, you could purchase many other variations including blank dice)
  • Calculators (yes, these are great, even in the early years. Think about using them to investigate numbers rather than simply as , computational devices)
  • Base 10 material (be careful how you ‘name’ these – using terms like ones, tens, hundreds and thousands limits their use. It is best to use the terms minis, longs, flats and blocks so they can be used flexibly to teach a range of whole number and measurement concepts)
  • Measurement materials (you’ll need a range of things to cover all aspects of measurement, eg. scales, tape measures, rulers, )
  • Pattern blocks (great for more than just exploring 2D shape – these can be used to teach fractions, place value, area, perimeter etc.)
  • Dominoes (one of my truly favourite things!)
  • Playing cards
  • Unifix blocks
  • Paper shapes (circles, squares, etc.) to promote a range of concepts including fractions, shape, and measurement

Of course, any resource is only as good as the teacher using it and the way it is integrated into teaching and learning. Prior to using any concrete material or resource, consider the purpose of the lesson and the mathematical concepts being covered. Also consider how you can make the most out of those resources – how will you differentiate the task, and how will you capture evidence of learning? This is where technology can play a useful role and allow teachers and students to capture evidence when working with concrete materials. Technology can also be used alongside concrete materials. For example, work with pattern blocks can be recorded using the Pattern Block App on an iPad. Or students could integrate their use of concrete materials with a verbal reflection or explanation using the Explain Everything app.

The best way to get the most out of concrete materials is to do some reading. There are many high quality resource books and there are also many great websites such as NCTM Illuminations that provide excellent teaching ideas. Once you see the potential of high quality, flexible concrete materials such as those listed above, your students will become much more engaged with mathematics and will develop deeper conceptual understandings.

And one last thing…students are never too old or too smart to benefit from hands-on materials so never keep them locked away in a cupboard or storeroom (the materials, not the students)! Students should feel they can use concrete materials when and if they need them. After all, we want our students to be critical, creative mathematicians, and hands-on materials assist learning, and promote flexibility in thinking and important problem solving skills.

Tips for Teachers: Critical ingredients for a successful mathematics lesson

What are the ingredients for an effective mathematics lesson? Teachers are continually faced with a range of advice or ideas to improve their mathematics lessons and often this just creates confusion. It’s a little bit like being a cook. New recipes appear online and in cookbooks on bookstore shelves, but often they’re just adaptations of classic recipes that have been around before, their foundation ingredients are tried and tested, and often evidence based. There are always the staple ingredients and methods that are required for the meal to be successful.

The following is a list of what I consider to be important ingredients when planning and teaching an effective mathematics lesson. The list (or recipe) is split into two parts: lesson planning and lesson structure.

Lesson planning:

  • Be clear about your goal. What exactly do you want your students to learn in this lesson? How are you going to integrate mathematical content with mathematical processes? (The proficiencies or Working Mathematically components) Will you consider the General Capabilities in your planning?
  • Know the mathematics. If you don’t have a deep understanding of the mathematics or how students learn that aspect of mathematics, how can you teach it effectively? Where does the mathematics link across the various strands within the mathematics curriculum?
  • Choose good resources. Whether they are digital or concrete materials, make sure they are the right ones for the job. Are they going to enhance students’ learning, or will they cause confusion? Be very critical about the resources you use, and don’t use them just because you have them available to you!
  • Select appropriate and purposeful tasks. Is it better to have one or two rich tasks or problems, or pages of worksheets that involve lots of repetition? Hopefully you’ve selected the first option – it is better to have fewer, high quality tasks rather than the traditional worksheet or text book page. You also need to select tasks that are going to promote lots of thinking and discussion.
  • Less is more. We often overestimate what students will be able to do in the length one lesson. We need to make sure students have time to think, so don’t cram in too many activities.
  • You don’t have to start and finish a task in one lesson. Don’t feel that every lesson needs to be self-contained. Children (and adults) often need time to work on complex problems and tasks – asking students to begin and end a task within a short period of time often doesn’t give them time to become deeply engaged in the mathematics. Mathematics is not a race!

Lesson Structure:

  • Begin with a hook. How are you going to engage your students to ensure their brains are switched on and ready to think mathematically from the start of each lesson? There are lots of ways to get students hooked into the lesson, and it’s a good idea to change the type of hook you use to avoid boredom. Things like mathematically interesting photographs, YouTube clips, problems, newspaper articles or even a strategy such as number busting are all good strategies.
  • Introduction: Make links to prior learning. Ensure you make some links to mathematics content or processes from prior learning – this will make the lesson more meaningful for students and will reassure anxious students. Use this time to find out what students recall about the particular topic – avoid being the focus of attention and share the lesson with students. Talk about why the topic of the lesson is important – where else does it link within the curriculum, and beyond, into real life?
  • Make your intentions clear. Let students know what they’re doing why they’re doing it. How and where is knowing this mathematics going to help them?
  • Body: This is a good time for some collaboration, problem solving and mathematical investigation. It’s a time to get students to apply what they know, and make links to prior learning and across the mathematics curriculum. This is also a time to be providing differentiation to ensure all student needs are addressed.
  • Closure: This is probably the most important time in any mathematics lesson. You must always include reflection. This provides an opportunity for students to think deeply about what they have learned, to make connections, and to pose questions. It’s also a powerful way for you, the teacher, to collect important evidence of learning. Reflection can be individual, in groups, and can be oral or written. It doesn’t matter, as long as it happens every single lesson.

There are many variables to the ingredients for a good mathematics lesson, but most importantly, know what and how you are teaching, provide opportunities for all students to achieve success, and be enthusiastic and passionate about mathematics!

Beach Towels and Pencil Cases: Interesting, Inquiry-based Mathematical Investigations

In several of my previous posts I discussed the importance of promoting critical thinking in mathematics teaching and learning. I’ve also discussed at length various ways to contextualise mathematics to provide opportunities for students to apply prior learning, build on concepts, and recognise the relevance of mathematics in our world. In addition, investigations provide excellent assessment material – usually when we assess in mathematics we ask for specific answers. In investigations, students can show us a range of mathematics, often beyond our expectations. They are also a great way to integrate other subjects areas such as literacy and science.

In this blog post I am going to share some ideas for open ended and inquiry-based mathematical tasks based on two items that most students would be familiar with – beach towels and pencil cases!

Pencil Cases

Let’s start with pencil cases. It’s the start of the 2018 school year next week and many children begin each school year with brand new stationery, in brand new pencil cases. Even if they’re not brand new, most children have a pencil case. I came across an interesting article relating to pencil cases a few days ago, and I think this could be used to spark interest and curiosity. The article can be found here:

Short activities:

  1. Who has the heaviest pencil case? Compare the mass of your pencil case with the pencil cases of your group members. Who has the lightest? Estimate the mass, then use scales to test your estimations. How close were the estimations?
  2. Estimate, then calculate the surface area of your pencil case. What units are the most appropriate to use? Explain how you measured the surface area.
  3. Faber Castell is a famous brand of pencils. Investigate the history of Faber Castell and illustrate this on a timeline.
  4. According to the Faber Castell website, it takes one ‘pinus caribaea’ tree 14 years to be ready to be used to manufacture pencils. Each tree can produce 2500 pencils. If one tree was allocated to each school, how many pencils do you think each child in your school might receive? How did you work this out?
  5. If each of the 2,500 pencils were sold for $1.50, how much do you think the entire tree be worth in pencil sales?

Investigations:

  1. At the beginning of each school year many children get brand new pens and pencils to take to school. Investigate how much it would cost to buy your stationary. Which shop offers the best value for money?
  2. Some pencil cases like the one in the photo and in the Missing Letter article have small clear plastic pockets to put your name in. If a pencil case has only eight pockets, is this enough for your name? Investigate the length of names in your class. What would be the average length name in your class? What else could you explore about names?
  3. The pencil case in the picture came with some pre-printed letters for the clear pockets. There are more of some letters than others. Investigate the most common letter occurring in students’ Christian names. Do you think it would be the same in all countries?
  4. Design and make a pencil case to suit your individual stationery needs. Write about the mathematics you use to do this.

Extension Activities:

  1. Design a new and improved pencil and explain the changes you have made.
  2. Design, justify, and create a marketing campaign for a new, ‘miracle’ pen.
  3. Research and discuss the following statement: “To save the environment, wooden pencils will no longer be manufactured”.

Promoting Curiosity and Wonder

Mathematical investigations should promote curiosity and wonder. The pencil case questions and investigations are open, yet provide some structure and support. They give enough detail to communicate the type of mathematics required to complete the task or investigation. Students should eventually be able to feel confident enough to come up with their own questions and follow their own path in terms of the mathematics they access and apply, just like mathematicians do.

Round Beach Towels?

In the last year or two a new beach towel has emerged onto the beach towel scene. It’s round. Now this idea immediately caused some concern for my mathematical brain. I had questions.

  • Is there more fabric in a round beach towel than a regular, rectangular beach towel?
  • Is there more fringe, and wouldn’t this make the towel more expensive?
  • How does one fold a round beach towel?
  • Could you wrap a round beach towel around you the way you wrap a rectangular beach towel?
  • How much more area on the beach gets taken up by people spreading round beach towels?
  • Does this mean less people get to lay on the sand?
  • Could you design a round beach towel that has a tessellating pattern?IMG_4837

All of the questions above can be explored using a range of mathematics…I wonder how many more questions your students could come up with?
