What this lesson shows
27 sits between 20 and 30. It is 3 from 30 and 7 from 20, so it rounds to 30.
The worked example
The lesson works this one step by step: 27 to the nearest ten. Then your kid tries one like it on paper.
The steps
- Between which two tens?
- Mark the middle
- Count the jumps
- Pick the closer ten
Helping at home
Name the tens first: 27 is 2 tens and 7 ones, so it sits between 20 and 30. Draw a line from one ten to the other, mark the middle, and count the jumps to each ten. It rounds to the closer one.
If your kid gets stuck
