Introduction
In this activity, we will be writing a number as tens and ones. The coins might help.
Example
Write the number as tens and ones.
Put the missing number in the box.
| 83 | = | + | 3 |
Answer
The silver coins add up to the number of tens.
50 + 20 + 10 = 80p
The bronze coins add up to the number of ones.
1 + 1 + 1 = 3p
| 83 | = | 80 | + | 3 |
Does that make sense?
Let's have a go at some questions and see if it becomes easier.
