10 Maths Challenges that use Cones

I am rather shocked that it’s taken me so long to blog about the mathematical value of cones. They are a wonderful resource yet are often overshadowed by the sleekness of sticks and the smoothness of stones. So this post is written in honour of the cone and its...

Must a triangle always have straight sides?

Last summer I was visiting Saughton Park and Gardens in Edinburgh. It is a very welcoming garden. Within formal garden area, there is this bedding display. I was fascinated by the layout and shapes of the beds. It was clearly not the level of formality of...

Wet Weather Nature Symmetry Circles

Today has been a wet, rainy day. It was perfect for creating nature circles – or mandalas – depending upon how you choose to introduce and contextualise the activity. For me, I am interested in the mathematical element of this work. I’ve blogged...

Multiplication Pebbles

Multiplication pebbles are a very simple resource. I have put 10 pebbles in one bag to represent the 3 times table. As illustrated above, each pebbles has the number 3 painted on it with acrylic deco pens. Each pebble is a different colour. For some children, learning...

A Number Pebble Game

Recently I was browsing Childhood 101’s blog and stumbled across this post about using Uno to play an attribute game. It reminded me of several summers of serious card playing where my sisters and I played a lot of “Black Jack” which is similar to...

Kaleidoscope Images and Symmetry

The kaleidoscope feature of Photo Booth on an iPad remains one of the funkiest ways of looking through the lens I know. It is a useful addition to any light and colour project because what one sees can be photographed. It can capture images for later use. Ordinary...

Celebrating 100 Days at School

How many days has it been since your class returned to school last August or September? You may need to do some counting on a calendar. For schools in Aberdeen City this is Friday 7th February. Naturally this is a lovely opportunity to celebrate all things 100 and of...

Nature Mastermind

Back in the Seventies, one of the most popular games which took the UK by storm was Mastermind. It was aimed at 8yrs olds and upwards. It’s a form of code cracking where you have to work out the hidden line of coloured pegs. It was developed from a traditional...

Daisy Footprints

We are all encouraged to work out our environmental footprint, but have you ever considered your impact on daisies? Luckily they are tough little flowers that seem to withstand people treading on them. A nice maths activity is to find out how many daisies you can...

Plant ID in a Parallel Universe

Plant identification is a quirky matter. As a child, I was not especially interested in wildflowers, trees or other plants. Family walks were decidedly boring if there was too much plant talk and not enough running, climbing and swinging thrown into the mix. So when...

A Maths Stick Picture Game

In my last post, 10 Little Stick Activities, I mentioned the game of Pick Up Sticks. This is fun, good for all ages and a nice way to introduce sticks to a class. Here’s another useful little idea that one course participant showed me when training in Perth last...

Stick Logic

One ongoing challenge for teachers is ensuring that children who finish earlier than others have something meaningful to move onto. There’s lots of possibilities outside and this stick activity is one such example. It can be completed in pairs or by children...

Algebraic Equations

The idea of objects representing numbers is not new and works well for reinforcing basic numeracy skills. In this activity children gather some natural objects from whatever is to hand and then create sums. Here’s what a Y5 (Primary 6) class devised when working...

Outdoor Maths: Angles and Numerals

This is a very simple investigation using sticks lying around. It works particularly well with twigs or sticks which can be easily broken or snapped to size. The challenge is to create the numerals from 1-9 with sticks. Now that is a nice challenge in the early years...
