Workshop:
Aiming High? Dig Deeper
Inspired by a staircase of natural numbers and in the context of learning to work like a mathematician in fascinating, captivating and absorbing classrooms, this DIY video workshop is for teachers K-12 who suspect students might learn more by digging deeper into a rich learning experience, than by moving on to the next something. Mathematics does not have to be taught the way it always has been. Using a maths journal is integral to the workshop.
The local leader arranges preparation, encourages discussion before, during and after the session and manages the use of time during the workshop. The video provides stimulus content. There are pauses for activity and discussion. Add your own pauses too as appropriate. Allow at least 1 hour for the session. This video can be used in sections over several sessions.

Workshop:
A School Without Books
A teacher once commented in a workshop that:
A school without tasks is like a school without books.
This DIY workshop gently leads participants through activities which draw out the features of using hands-on problem solving tasks which might stimulate a person to make this comparison. Along the way the structure, navigation tools, content depth and teaching craft focus of Mathematics Centre are explored through the investigations Truth Tiles 2 (Years 2 - 10) and The Mushroom Hunt (Years 4 - 10). The workshop begins by imagining the possible educational losses in a school without books and ends by imagining the possible educational gains in a school with tasks.
The local leader arranges preparation, encourages discussion before, during and after the session and manages the use of time during the workshop. The video provides stimulus content. There are pauses for activity and discussion. Add your own pauses too as appropriate. Allow at least 1 hour for the session.

Adventure of the Sphinx
Dani and Alex introduce you to the amazing investigation by Pam McGifford's Year 8 class at Cressy District High School into the remarkable properties of a shape called the Sphinx. You will discover unexpected connections between shape, pattern, measurement and algebra and you will be stunned by the competence and confidence of these young people who are Learning to Work like a Mathematician. Perhaps the most amazing thing of all - or perhaps not if you have ever been captivated by mathematics - is that the students did most of their problem solving, as a group, on their own during Mrs. McGifford's absence. Pam had introduced the problem to them using Sphinxes made by her husband. When she returned to school and saw what her children had achieved and the confidence and enthusiasm with which they expressed it, she encouraged them to publish their work 'just like a mathematician would'.

Billiard Ball Bounces
Billiard Ball Bounces is a Maths300 lesson which doesn't grow from a task. But as Matt Skoss shows us in this video made at a professional development session, it can start very practically on the floor. All you need is a set of cards about 20cm square and a length of coloured cord. The cards are used to make a 'billiard table' of any size, in this case 6 x 5, and the cord traces the path of a ball hit from the bottom left pocket. The challenge is to predict the number of bounces before the ball 'drops' into a corner pocket.

Does This Solve 'A Stacking Problem'?
A student at Living Waters Lutheran College is challenging us to decide if these moves are a solution to Task 149, A Stacking Problem. You might like to introduce your students to the problem, let them play for a while, then ask them to answer the student's question: Do my moves solve the problem?
- If yes, explain why.
- If no, explain why not?
- Do you think mathematicians make mistakes?

Four & Twenty Blackbirds
In this Year 7 class at Trädgårdsstadsskolan, Sweden, the teacher explains the problem at a central table using a fish bowl strategy. The table is a courtyard and around the perimeter there are eight feeding platforms, one at each corner and one at the midpoint of each side.
Twenty-four blackbirds land so that there are nine along each side. How are they arranged?
Video 1 shows that this story shell has captured the students' interest. The conversation is in Swedish.
Video 2 is later in the lesson when Sofia, Maria & Annika explain, in English, how they can find every solution.

Growing Tricubes
This class of trainee secondary teachers at Högskolan Malmö had discovered that Tricubes can grow reasonably easily by powers of 2. They had made Size 1, Size 2 and Size 4 by working together.
- But what happened to Size 3?
- If there is a Size 3 could we predict the number of Tricubes to make it?
- If we have that number, is it possible to make it?
Video 1 shows the struggle to try to build Size 3.
Video 2 is just a few minutes later when it has been achieved.
But that just leads to asking more questions...

Haberdasher's Problem
The original puzzle was to dissect an equilateral triangle to make pieces that could be rearranged as a square. That puzzle was solved by Henry Dudeney in the late 1800s and these Swedish teacher trainees have the pieces that result from the dissection. However, it is clear that the challenge of using these to make both the square and the equilateral triangle is non-trivial. When achieved, it is the tip of the iceberg which then interests students in the original challenge and develops into a history of mathematics lesson requiring significant geometry.

Hearts & Loops 1, 2 & 3
Nick and Owen, Year 4, Ashburton Primary School, are learning to work like a mathematician. First they become interested in a problem, in this case a problem from topology related to open and closed curves. If they can separate the heart from the loop, then both curves were never closed.
For a mathematician, solving a problem is not enough. A mathematician must be able to explain the solution.
Nick shows us that he can separate the pieces (Video 1). Owen shows us that he can reconnect them (Video 2). Then Owen introduces Nick (Video 3) who, with his hands behind his back, teaches the teacher how to separate the pieces.

How Does it Feel to Work Like a Mathematician?
A mathematician's work begins with an interesting problem. Kathy and Steve are certainly interested in the problem Squound which was presented to them in a workshop. Join them in the middle of their muddle to get a sense of what your students need to experience if they are ever to learn how to work like a mathematician. Then investigate the problem for yourself - it will take a while - and come back to watch the video again to reflect on how it feels to work like a mathematician. Consider too the features which have made it more likely that these teachers would be fascinated, captivated and absorbed by Squound.

In Between Time & Wait One Minute
These two videos are part of the learning involved in the Maths At Home activity titled In Between Time. The first introduces the activity and the second offers a closing challenge. It is essential that the learner has an analogue clock which they can manipulate and preferable that they have a partner. The initial video demonstration invites students to investigate the interconnectedness of the hour and minute hands. The activity moves on to a thirty minute difference from a given time, a challenge which has two answers each time. The second video concentrates on the second hand and its relationship to minutes.
The MAH form of In Between Time derives from Task 25, with the same name, which itself is a partner to Task 22, Time Together.

Multiplication with Poly Plug
Back Story
About 3 months before making the video, this Year 9 student went with her mum to visit the grandparents for Sunday lunch. When the adult conversation lost her interest, she wandered off to the bedroom where the grandchildren stay over. She found Poly Plug in the toy cupboard and happily sat on the carpet and began playing. She drifted into building walls, then noticed patterns and just before leaving invited the adults to look at what she had discovered.
The day before the video was made the grandfather received a text. When you pick me up after school tomorrow can you bring the Poly Plug. I want to make a video for my algebra class.

My Professional Learning 1, 2 & 3
In three short videos three teachers explain what they learnt in a full day course titled Learning to Work Like a Mathematician.
The description of the course was:
For a mathematician to start work they must first have an interesting problem. Their work involves applying reasoning, questioning, justification and communication processes in the pursuit of a solution. Therefore when we view the school curriculum as learning to work like a mathematician, we begin with problems - genuine problems with unknown answers, not repetitive exercises with expected answers - and select teaching craft designed to fascinate, captivate and absorb learners.
The course was included in the 2015 Annual Conference of the Association of International Schools of Africa in both a primary and a secondary version. These videos were made voluntarily at the end of the Primary day.

Potato Olympics 1
Anne Mullans, St. Patrick's Primary School, Murrumbeena, produced this inspirational video to stimulate their Potato Olympics adventure in 2008. That year also happened to be the official human year of the potato, but to potatoes every year is the year of the potato, so the video remains very relevant to any Olympic year. Use it as is, or get inspired and create your own 'video-duction' to this event.
Potato Olympics derives from the work of one Swedish teacher recorded in this article, Potatis Matematik, published in The Classroom Connection, Vol.4 No.2, April - June 1996. From there, various teachers from many places have played with the idea of using potatoes as a concrete teaching aid and, somewhere, the idea of Potato Olympics, as described in Anne's video was born. Maths300 Lesson 67, has collected many of these ideas and includes fabulous Classroom Contributions from Year 7, Luther College, Victoria ... Year 5/6 Kingston, Tasmania ... and Fregon School in very far outback South Australia.

Seats on the Bus
Junior Primary children at Loxton North Primary School are on a Multiplication Journey. Today their teacher has set out the children's chairs in an array facing forward, just like rows of seats on a bus. The children learn about equal rows of people on the bus and transfer their learning to a model of the context. You can see and sense groundwork developing for multiplication, the commutative law, factors, multiples, primes and times tables.
The video was developed in the context of a 6 Day Professional Development course which drew significantly from Calculating Changes for many of its activities.

Working Mathematically with Viruses
These three videos are embedded in the activity notes for a series of investigations titled Working Mathematically with Viruses. They will have most meaning if viewed from within that context (see below).
All our work is based around the concept of learning to work like a mathematician, rather than just practising the skills of a mathematician, so in this activity the focus is on:
- developing and interrogating a model of virus spread
- the effect of public health actions on the spread
- and the potential of a vaccine to control the virus more permanently if enough people accept the invitation to immunise.
The model is presented through Excel programming by Dr. Ian Lowe and a variety of teaching craft, including these videos.
- Part 1: Virus Basics (Time: ... 5:47)
- Part 2: Recovery (Time: ... 5:13)
- Part 3: Effect of Vaccination (Time: ... 4:23)

Yellow to Blue
Bella, Emma, Amy & Beatrice, Year 6, Camberwell Primary School, describe their insightful algorithm for changing yellow to blue. The problem uses plugs with a different colour on each side. The challenge is to begin with four yellow plugs and by turning over all except one on any turn, to change them all to blue. You might like to try it yourself first because it isn't as easy as the girls make it look. Instead of plugs use four scraps of paper with a cross on one side of each.
- Learn more about Yellow to Blue which derives from Task 132, Red To Blue.
- Maths300 members can find out more about this investigation in Lesson 127, Red To Blue.
