Leaping lizards (HarperCollins, 2005)
"Level 1, Counting by 5s and 10s"--Cover. -- Learn to count by 5s and 10s by counting the lizards as they arrive for a show. It's almost time for the show to begin -- but where are all the lizards? As a frantic snake looks high and low for the performers, they start to arrive, first by fives and then by tens. Will all fifty lizards show up in time? A lively rhymed story and pictures bursting with color introduce the math concept of counting by fives and tens, an important first step in learning addition and multiplication. -- Ages 3 and up.
