What 3rd grader learn about division
In grade 3 (class 3), children learn what division means: sharing into equal groups and making groups of a given size. They connect division to multiplication with fact families, learn the division facts to 100 ÷ 10, and solve word problems with equal groups and arrays.
- 3.OA.A.2: understand division as sharing into equal groups or making equal groups.
- 3.OA.A.3: solve division word problems within 100 with equal groups and arrays.
- 3.OA.B.6: understand division as an unknown-factor problem: 32 ÷ 8 asks 8 × ? = 32.
- 3.OA.C.7: divide within 100 fluently by the end of the year.
The big idea in grade 3
Grade 3 is the year division arrives. Children learn that division means sharing into equal groups or grouping into groups of a given size, and that it is multiplication turned around.
That second idea does most of the work. A child who knows 6 × 7 = 42 can answer 42 ÷ 6 and 42 ÷ 7 at once. So the times tables and division facts are best learned side by side, as fact families.
By the end of the year, children should divide within 100 fluently (3.OA.C.7). Start with ÷ 2, 5 and 10, then 3 and 4, then the harder 6, 7, 8 and 9. Keep practice short and daily.

- Write the fact family for 6, 7 and 42.
- Know the division facts to 100 ÷ 10, with the 2, 5 and 10 facts quick.
- Say why 7 ÷ 0 cannot be done.
- Solve a one-step division story within 100.
Unsure where your child is? The division levels page has a short test for every step from sharing to 2-digit divisors.
A 4-week plan for 3rd grade division
| When | Focus |
|---|---|
| Week 1 | Sharing and grouping with real objects; the ÷ sign |
| Week 2 | Dividing by 2, 5 and 10; fact families |
| Week 3 | Dividing by 3 and 4; arrays; the rules for 0 and 1 |
| Week 4 | Dividing by 6, 7, 8 and 9; word problems |
Add 5 minutes of fact practice every day with the division practice trainer, and a weekly division speed test. Keep the matching times tables going too.

What to say to your child
A short script for teaching it the first time. Pause after each line and let your child do the next step.
- “Share these 15 grapes between the 3 of us.” (5 each.) “That’s 15 ÷ 3 = 5.”
- “What is 3 × 5?” (15.) “So division is multiplication backwards.”
- “If 6 × 7 = 42, what is 42 ÷ 7?” (6!)
- “How many 4s in 28? Halve twice.” (14, then 7.)
- “Make up a sharing story for 20 ÷ 4.”
More worked examples
Example 1: sharing: 18 ÷ 3
Share 18 counters into 3 groups, one at a time. Each group has 6. So 18 ÷ 3 = 6.
Example 2: using a fact family: 56 ÷ 8
Think 8 × 7 = 56. So 56 ÷ 8 = 7 and 56 ÷ 7 = 8.
Example 3: a word problem
“24 children sit at 4 tables equally.” 24 ÷ 4 = 6 children at each table.

Five minutes a day
Short daily practice beats long weekend sessions.
Talk it through
Ask “how did you work that out?” for one problem each day.
Use real life
Sharing snacks, splitting bills and working out prices per item are all division.

Questions parents ask
What division should a 3rd grader know?
What division means (sharing and grouping), how it links to multiplication, the division facts to 100 ÷ 10 by the end of the year, and one-step division word problems.
Should my child learn times tables before division?
Learn them together. Every division fact comes from a times table fact, so 7 × 8 = 56 gives 56 ÷ 8 = 7 and 56 ÷ 7 = 8.
