What this lesson shows
Fixes a mistake
65 is right between 60 and 70. Halfway rounds up, to 70.
The worked example
The lesson works this one step by step: 65 to the nearest ten. Then your kid tries one like it on paper.
The steps
- Between which two tens?
- Count the jumps
- Same both ways: halfway
- Halfway rounds up
Helping at home
Count the jumps to each ten. When they are the same, the number is exactly halfway, and it rounds up to the bigger ten.
If your kid gets stuck
Is it exactly halfway?
Watch it with Lux
With Lux, this lesson is a narrated video and a printed page your kid works on. Then Lux helps with the same math on their own worksheet, one question at a time.
