Count by 5s from 15 to 50
1 Start at 15
Here is a number line.
2 Jump by 5s
Each jump is 5 more.
We say the number where we land.
3 Write the numbers
Now we write them in a row.
We stop at 50.
= 15, 20, 25, 30, 35, 40, 45, 50
4 Check
Look at the ones digits: 5, 0, then again.
They make a pattern.
Yes!
It works.
ones: 5, 0, 5, 0, 5, 0, 5, 0
Let's look back.
First: start at 15.
Then: jump by 5s.
Then: write the numbers.
Last: check.
Answer
= 15, 20, 25, 30, 35, 40, 45, 50
