Did you Know? 

The caterpillars of many butterfly species prefer one type of plant to feed on. The monarch butterfly caterpillars of North America feed on milkweed plants. Milkweed plants are so called because of the creamy white liquid that oozes from broken stems.

Use PAWS, counters and column addition to solve the following word problem.

Two monarch butterfly caterpillars, one male and the other female, were feeding on a milkweed plant. Before turning into a chrysalis, the male caterpillar ate 124 milkweed plant leaves. The female caterpillar ate 73 milkweed plant leaves.

How many milkweed plant leaves did the male and female monarch butterfly caterpillars eat altogether?
