The bugs are on parade. One is big, the next is bigger, and the next is the biggest bug of all.

In The Best Bug Parade children are introduced to this concept by some goofy-looking bugs who form a parade. Author Stuart J. Murphy and illustrator Holly Keller have made comparing sizes an enjoyable activity for the very youngest math student.
