# Column addition 4: Lesson 2: bats

## The Maths Bit!

In this exciting lesson, you will be need to solve a range of addition word problems that feature bats. Try using **PAWS** to arrive at the right answer!

**P ** = Picture the problem in your mind.

**A **= Annotate the word problem by highlighting the important information.

**W** = Write down the number sentence that needs to be solved.

**S** = Solve the number sentence using an efficient strategy.

**Prior learning: ** 3-digit column addition with one exchange

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

In the roof spaces of two large barns that were 1,565 kilometres apart, there were two enormous pipistrelle bat roosts. In one barn, 1,346 bats were roosting, while in the other barn, 1,325 bats were roosting.

**How many pipistrelle bats were roosting altogether in the two barns?**

**Did you know?**

The place a bat lives and sleeps is called its roost. Hollow trees, caves and old buildings are common places for sleeping bats. Interestingly, these winged mammals hang upside-down because they cannot take to the air from the ground.
