Origami Checkerboard Puzzles

Take a square piece of paper that is white on one side and coloured on the other, and fold it so that the coloured side makes the pattern shown in the figure on the left.

This can be done in only five folds. (Here we are counting only the folds used, not folds we might need to get exact landmarks.)

 

Have Fun!

More shapes are shown below. The numbers in the squares give the minimum number of folds that are possible.
