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

After 3 months, a leaf cutter ant colony had grown in size to include 13,256 ants. A month later, following the hatching of the queen’s eggs, a further 14,963 ants were added to the colony.

**How many leaf cutter ants were in the colony after this 4 month period?**

**Did you know?**

Unable to digest the tough leaves that they cut, worker leaf cutter ants carry leaf parts underground. The ants mash up the leaf parts to create a compost, which is used to grow a type of fungus that feeds the colony.
