Flip Flops are based on a grid of 4 x 4 squares. Ten of the squares contain an image.

The grid may be folded to reveal any number from zero to ten pictures. It may be folded in many ways to partition the ten pictures.

Pictures may be used to represent more than one number. For example, each of the stars shown opposite can also represent five, and the faces have eyes open and closed.

There are three different arrangements of the pictures on a page, to offer some variety. These are called Type 1, Type 2 and Type3. You might like to experiment with double sided flip flops, possibly with different arrangements on each side.

For best results, flip flops should be cut up into squares and laminated, with small gaps between the squares. This allows easier folding and you can  make the flip flops larger.

Type 3 is also good for fractions, since the four quarters of the grid contain respectively, one, two, three and four images.
