3.OA.A.3 games

Solve multiplication and division word problems within 100.

3.OA.A.3 is part of the Common Core State Standards for Mathematics. These 2 games practice it. Standards vary by state, so check with your kid’s teacher for the exact match.

The games

Kangaroo Hops: A kangaroo makes equal hops along a number line, so 4 × 3 is three hops of four. Kids say where it lands, write the multiplication, work out how many hops, then take on harder facts and word problems.

Mystery Factor: Each problem is a detective case with a hidden number under a card. Kids find missing factors, pick facts that belong to a fact family, divide, and solve word problems. A miss opens a clue panel with the equal groups drawn out.

Practice it at home

Take giant steps of the same length across a room and count by that number with each step.
Ask division as a missing factor: 24 ÷ 6 is the same as asking what times 6 makes 24.
