What this lesson shows
Fixes a mistake
5/8 is 5 divided by 8, not 8 − 5.
The worked example
The lesson works this one step by step: 5 ÷ 8. Then your kid tries one like it on paper.
The steps
- The bar is not minus
- Top ÷ bottom
- Tell a sharing story
Helping at home
The fraction bar means divide: 5/8 is 5 ÷ 8, 5 things shared by 8. It never means minus. A fraction with a smaller top than bottom is less than 1, which helps catch the slip.
If your kid gets stuck
The bar means divide: top ÷ bottom.

Standards
- Common Core 5.NF.B.3
Interpret a fraction as division of the numerator by the denominator (a/b = a ÷ b). Solve word problems involving division of whole numbers leading to answers in the form of fractions or mixed numbers, e.g., by using visual fraction models or equations to represent the problem. For example, interpret 3/4 as the result of dividing 3 by 4, noting that 3/4 multiplied by 4 equals 3, and that when 3 wholes are shared equally among 4 people each person has a share of size 3/4. If 9 people want to share a 50-pound sack of rice equally by weight, how many pounds of rice should each person get? Between what two whole numbers does your answer lie?
