Worksheet Overview

This activity focuses on counting and comparing numbers.

Example

Joe eats 13 sweets.

Kiran eats 10 sweets more than Joe.

How many sweets does Kiran eat?

Write the number that is 10 more than 13.

Start at 13 and then count 10 more.

13 + 10 = 23

Another way to think of it is to split your starting number into tens and ones. 13 is 1 ten and 3 ones.

If you add on 10, you only need to change the number of tens, from 1 ten to 2 tens. You don't need to change the number of ones.

So, 13 add 10 becomes 23.

Easy, right?

Let's try some questions now.
