Making these step books are so easy and can be used for just about anything. This book was made with 2 sheets of plain copy paper. Lay the two sheets on a table on top of each other, staggered about 1 inch apart. Fold them down in half so each "step" is about 1 inch. Staple at the top. We made this step book during our bird unit. The kids will decorate the cover and write and illustrate a fact under each flap.
