Let’s make a tessellating shape.
You need a 4 cm square of cardboard, scissors and sticky tape.
1 Draw a simple shape on one side of your square.
2 Cut it out.
3 Sticky tape it to the opposite side.
Hint. It is a good idea to sticky tape it front and back.

You now have a tessellating shape.
(You can start with a simple shape, eg and then make harder ones.)
1 Trace around your shape to make a colourful tessellating pattern.
