Here's a simple way to make a Tangram without any measuring or ruling lines. All you need is a square of paper and some scissors to cut out the shapes when you've finished folding. Follow the steps shown in each diagram and remember that every fold you make is finding half of a shape or line.
Now you can play around and make lots of pictures and puzzles - like a dog, boat, house, duck, rocket or rabbit. If you want a challenge, see if you can make all the letters of the alphabet using all seven shapes each time. Bet you can't!
