Digit Dog was watching the 10th Bug Squadron marching past but he was a little late and some of the bugs had already marched under the leaf. He is wondering how many are under the leaf.
How many bugs are in the 10th Squadron altogether?
How many groups of 2 can they make?
How many bugs can you see? How many groups of 2 can you see?
How many bugs are under the leaf? How many groups of 2 are under the leaf?
How can you work it out?
