First you will need a piece of paper. It needs to be the size or the dimensions of a bank note. If you have green or brown paper that's fantastic, and will give your amphibian a real frog or toad appearance.
With the paper laid horizontally, fold the top right hand corner down to the bottom edge to make a triangle. Then unfold.
Take the bottom right hand corner and take it up to the top edge and make a triangle. Then unfold. The makes an 'X' in one end of the paper.
Fold the paper in half-length ways so that the new fold line is at the base of the 'X' and unfold.
Turn the paper so it lies vertically, with the 'X' furthest away from you.
Pull the paper on either side of the 'X' together, and the top part down, the paper will naturally do its own thing with the creases that make up the 'X'. It will create a triangle shape with 2 flaps directly on top. Flatten the paper to make nice crisp folds.
Take the bottom corner of each flap in turn, and fold it up to the top point of the triangle to crate the frog's forelegs. It also makes a diamond like shape on the form.
Make a fold in the paper at about half way and fold the straight end up and over the diamond end. Fold the work flat. Then fold the straight part back and forth (to look like a fan or a concertina) 3 more times to form the back legs. Pull them out a bit to relax the folds and to make it springy.
Turn the frog over and arrange the legs. You can either draw on eyes, but if you have any, it's fun to use wobbly stick on eyes.
You can give your paper frog a long fly catching tongue. Take a long thin piece of red paper and roll it up tightly, hold it for a couple of second and then release. Glue the end of the tongue and stick it to the frog's mouth at the side.
To make the frog jump, run your finger down his back, compressing his back legs like a spring and he will hop. Make a few frogs and have a national frog-hopping race.
