What this lesson shows
A table of jump-rope counts: one says twenty, one is blank, one says 4000. Write twenty as 20, leave the blank out, and check the 4000, likely a typo for 40.
The worked example
The lesson works this one step by step: jump counts 35, twenty, blank, 4000, 42, 28. Then your kid tries one like it on paper.
The steps
- Words: write the number
- Blank: leave it out, not 0
- Cannot be right: check it
- Then use the clean data
Helping at home
Read each list aloud. Your kid writes a clean list: every count as a number, the blank left out, and the count that cannot be right checked. Ask why a blank is not the same as 0.
If your kid gets stuck
Write a clean list beside it.
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.
