I had fun creating this book today while my kids were in special classes. I plan to print the book on cardstock and then cut all but the pages in half, except the back page. I will then make sure the numbers and pumpkins are out of numerical order and bind the left side of the book (numbers) and bind the right side of the book (pumpkins). I will try to take a picture and add it later. For now, here is the printable if you'd like to use it.
