All
you need to make the

is
a square piece of paper.

Sides
of 20 cm give a good size which is easy to

handle but you could make it much larger or smaller.

To
prepare the paper fold it to give the creases shown here.

Make
sure the creases are crisp and fold each crease

forwards and backwards.

This
makes the paper flexible.

**Warm up Puzzles**

To start
you going here are some simple shapes that you can fold from the square.

Now
here are some symmetrical concave polygons that you can create from the square.
You will need to use “tuck in “ folds. All shapes are shown the same scale as the original
square.

Original square

Just
as with the traditional Tangram it is also possible to
create picture shapes. If you create some new ones please let me know.

**The Boat** **The**** Bird**

**Pattern Puzzle**

Using
the same square as before,

now
colour part of it black as shown here:

Now see if you can
fold up the paper to give a square

(a quarter the size of the original square) with these

patterns.
