In this feature for Primary teachers, you will find tasks to help learners develop their flexibility in a geometrical context. A flexible approach applies to a range of situations - perhaps being stuck on a problem and being flexible to try an alternative path; perhaps recognising that a task can have more than one solution; perhaps checking a solution using a different approach; or perhaps thinking flexibly to create a new problem related to one you have just tried. We hope you enjoy sharing these tasks with your classes.

In this article for primary teachers, Ems explores ways to develop mathematical flexibility through geometry.

Challenge Level

Try continuing these patterns made from triangles. Can you create your own repeating pattern?

Challenge Level

Can you describe a piece of paper clearly enough for your partner to know which piece it is?

Challenge Level

Take it in turns to make a triangle on the pegboard. Can you block your opponent?

Challenge Level

Here are shadows of some 3D shapes. What shapes could have made them?

Challenge Level

If you split the square into these two pieces, it is possible to fit the pieces together again to make a new shape. How many new shapes can you make?

Challenge Level

Can you each work out what shape you have part of on your card? What will the rest of it look like?

Challenge Level

Can you make five differently sized squares from the interactive tangram pieces?

Explore our selection of interactive tangrams. Can you use the tangram pieces to re-create each picture?

Challenge Level

Can you find out which 3D shape your partner has chosen before they work out your shape?

Challenge Level

Use the information on these cards to draw the shape that is being described.

Challenge Level

Are these statements always true, sometimes true or never true?

Challenge Level

This was a problem for our birthday website. Can you use four of these pieces to form a square? How about making a square with all five pieces?

Challenge Level

This practical problem challenges you to make quadrilaterals with a loop of string. You'll need some friends to help!
