This challenge invites you to create your own picture using just straight lines. Can you identify shapes with the same number of sides and decorate them in the same way?

Draw three straight lines to separate these shapes into four groups - each group must contain one of each shape.

Use the interactivity to make this Islamic star and cross design. Can you produce a tessellation of regular octagons with two different types of triangle?

What does the overlap of these two shapes look like? Try picturing it in your head and then use the interactivity to test your prediction.

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

Can you cut a regular hexagon into two pieces to make a parallelogram? Try cutting it into three pieces to make a rhombus!

Billy's class had a robot called Fred who could draw with chalk held underneath him. What shapes did the pupils make Fred draw?

Ahmed has some wooden planks to use for three sides of a rabbit run against the shed. What quadrilaterals would he be able to make with the planks of different lengths?

What shape is the overlap when you slide one of these shapes half way across another? Can you picture it in your head? Use the interactivity to check your visualisation.

Can you help the children in Mrs Trimmer's class make different shapes out of a loop of string?

How many DIFFERENT quadrilaterals can be made by joining the dots on the 8-point circle?

Find the missing coordinates which will form these eight quadrilaterals. These coordinates themselves will then form a shape with rotational and line symmetry.

The large rectangle is divided into a series of smaller quadrilaterals and triangles. Can you untangle what fractional part is represented by each of the ten numbered shapes?

A task which depends on members of the group noticing the needs of others and responding.

How many rectangles can you find in this shape? Which ones are differently sized and which are 'similar'?

I cut this square into two different shapes. What can you say about the relationship between them?

Can you draw a square in which the perimeter is numerically equal to the area?

Investigate the different shaped bracelets you could make from 18 different spherical beads. How do they compare if you use 24 beads?

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