In how many ways can you fit two of these yellow triangles together? Can you predict the number of ways two blue triangles can be fitted together?
We can cut a small triangle off the corner of a square and then fit the two pieces together. Can you work out how these shapes are made from the two pieces?
Use the three triangles to fill these outline shapes. Perhaps you can create some of your own shapes for a friend to fill?

Make a mobius band and investigate its properties.
Make a chair and table out of interlocking cubes, making sure that the chair fits under the table!
Have you noticed that triangles are used in manmade structures? Perhaps there is a good reason for this? 'Test a Triangle' and see how rigid triangles are.
Surprise your friends with this magic square trick.
Follow these instructions to make a five-pointed snowflake from a square of paper.
Did you know mazes tell stories? Find out more about mazes and make one of your own.
It's hard to make a snowflake with six perfect lines of symmetry, but it's fun to try!
Can you make the most extraordinary, the most amazing, the most unusual patterns/designs from these triangles which are made in a special way?
Can you see which tile is the odd one out in this design? Using the basic tile, can you make a repeating pattern to decorate our wall?
Kaia is sure that her father has worn a particular tie twice a week in at least five of the last ten weeks, but her father disagrees. Who do you think is right?
Using different numbers of sticks, how many different triangles are you able to make? Can you make any rules about the numbers of sticks that make the most triangles?
Follow the diagrams to make this patchwork piece, based on an octagon in a square.
This practical problem challenges you to create shapes and patterns with two different types of triangle. You could even try overlapping them.
Have a go at drawing these stars which use six points drawn around a circle. Perhaps you can create your own designs?
Can you split each of the shapes below in half so that the two parts are exactly the same?
Move four sticks so there are exactly four triangles.
A group of children are discussing the height of a tall tree. How would you go about finding out its height?
Explore the triangles that can be made with seven sticks of the same length.
Can you make a rectangle with just 2 dominoes? What about 3, 4, 5, 6, 7...?
Using a loop of string stretched around three of your fingers, what different triangles can you make? Draw them and sort them into groups.
Arrange your fences to make the largest rectangular space you can. Try with four fences, then five, then six etc.
You'll need a collection of cups for this activity.
For this activity which explores capacity, you will need to collect some bottles and jars.
Have you ever tried tessellating capital letters? Have a look at these examples and then try some for yourself.
We have a box of cubes, triangular prisms, cones, cuboids, cylinders and tetrahedrons. Which of the buildings would fall down if we tried to make them?
In this activity focusing on capacity, you will need a collection of different jars and bottles.
What shapes can you make by folding an A4 piece of paper?
