What this lesson shows
7/10 is 0.7 and 7/100 is 0.07, read aloud the same way.
The worked example
The lesson works this one step by step: 2 37/100. Then your kid tries one like it on paper.
The steps
- Ones, then a point
- Tenths, then hundredths
- A 0 holds an empty place
- Read it by the last place
Helping at home
Draw a chart with ones, a point, tenths, and hundredths. Put each digit in its place, a 0 in any empty place before the last digit, and read the decimal back by its last place: it should sound like the fraction.
If your kid gets stuck
Which place does the last digit go in?
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.
