When you **ADD,** things get bigger, longer or more.

**Example**

Jane has 12 pencils.

Bill has 15 pencils.

How many do they have in total?

**Answer**

Add together 12 and 15.

Start at 12 and count on 15 to get 27 pencils.

**12**... 13... 14... 15... 16... 17... 18... 19... 20... 21... 22... 23... 24... 25... 26... **27**

When you **SUBTRACT,** things get smaller, shorter, fewer or less.

**Example**

Jane has 17 marbles and gives 5 to her brother Bill.

How many does she have left?

**Answer**

Subtract 5 from 17 (17 - 5).

Start at 17 and count back 5.

**17**... 16... 15... 14... 13... **12**

She has 12 left.
