Step by step
The question
Question: what number is between 29 and 31?
What number is between 29 and 31?
We write it in numbers.
The box is the number we want.
= 29, □, 31
1 Find both numbers
Here is a number line.
2 Look between them
Between means in the middle.
The number in the middle is 30.
3 Write the number
So 30 is between 29 and 31.
= 29, 30, 31
Careful!
After 9 ones, the ones start again at 0.
The tens go up by 1.
Careful: 29 → 30: the ones start again at 0
4 Check
After 29 comes 30.
After 29 comes 30
Before 31 comes 30.
Yes!
It works.
Before 31 comes 30
Let's look back.
First: find both numbers.
Then: look between them.
Then: write the number.
Last: check.
