Which Operation Should I Use?
| The story… | Operation | Clue words (not always!) |
|---|
| puts two amounts together | Add + | in all, altogether, total, together |
| takes some away, or compares two amounts | Subtract − | left, how many more, how much longer |
| has equal groups and asks for the total | Multiply × | each, every, rows of, in all |
| shares a total equally, or makes groups of a size | Divide ÷ | equally, each, split, how many groups |
Clue words help, but always picture what is happening. “Each” appears in both multiplication and division stories — the question tells you whether the total or the groups are unknown.
Reading a Bar Model (Tape Diagram)
Multiplication: 4 bags with 6 marbles in each. The parts are known, so the ? is over the whole bar.
Division: 24 stickers shared equally among 4 friends. The total is known, so the ? goes in each part.
For Parents and Teachers
Each problem is one step and matches Grade 3 standards: multiplication and division within 100 (3.OA.A.3) and addition and subtraction within 1,000 (3.NBT.A.2). Division always comes out evenly, and subtraction never goes below zero.
If a student gets stuck, Show Me One Step completes only the current step — choosing the operation, choosing the bar model, writing the equation, or finding the answer — and then gives control back. Wrong choices simply get a gentle hint and another try.
