What this lesson shows
3/4 is 1/4 + 1/4 + 1/4, and 7/4 goes past one whole.
The worked example
The lesson works this one step by step: 7/4. Then your kid tries one like it on paper.
The steps
- One part is a unit fraction
- Count to one whole
- Keep counting past it
- Add the unit fractions
Helping at home
Draw bars cut into the bottom number of parts and shade one part at a time, counting as you go. Write one unit fraction for each part shaded, with a plus between them.
If your kid gets stuck
Write 1 over the bottom number once for each part.

Standards
- Common Core 3.NF.A.1
Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b. - Common Core 3.NF.A.3c
