The game

Mystery Factor Missing factors, fact families and division3rd grade

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

Ask division as a missing factor: 24 ÷ 6 is the same as asking what times 6 makes 24.
