What this lesson shows
7/4 and 1 3/4 are the same amount, shown with fraction bars.
The worked example
The lesson works this one step by step: 7/4. Then your kid tries one like it on paper.
The steps
- A whole is all its parts
- Fill whole bars
- Shade the rest
- Wholes and the rest: a mixed number
Helping at home
Draw bars for wholes, each cut into the fraction’s parts, and shade one part at a time until you reach the top number. Full bars are the wholes; the rest is the fraction part.
If your kid gets stuck
How many full bars? How many parts left?
