Square Tangram

Age 7 to 11 Challenge Level:

Square Tangram

A set of shapes has five pieces.
First, make a square using four pieces.
Then, make a square using all five pieces.

Full screen version

Then add another set of five pieces (so now there are ten) and make a square with all of them.

Full screen version

You could download this sheet with two sets of pieces for printing and cutting.

Why do this problem?

This tangram is a challenging context in which to remind pupils of the properties of squares.

Possible approach

If preferred, they could print off  this sheet and cut out the tangram pieces rather than using the interactivity.

In both cases, it is important that children become more confident at simply "having a go" and playing with their ideas to begin with, rather than feeling that they need to know the "right" way to do it from the start. You might like to model this trial and improvement approach, perhaps on an interactive whiteboard, emphasising that we can learn a lot from what doesn't work.
