Step by step
The question
Question: what number is between 99 and 101?
What number is between 99 and 101?
We write it in numbers.
The box is the number we want.
= 99, □, 101
1 Find both numbers
Here is a number line.
2 Look between them
Between means in the middle.
The number in the middle is 100.
3 Write the number
So 100 is between 99 and 101.
= 99, 100, 101
Careful!
After 9 ones, the ones start again at 0.
The tens go up by 1.
Careful: 99 → 100: the ones start again at 0
4 Check
After 99 comes 100.
After 99 comes 100
Before 101 comes 100.
Yes!
It works.
Before 101 comes 100
Let's look back.
First: find both numbers.
Then: look between them.
Then: write the number.
Last: check.
