Math Games
With Jane and Joanne

The Missing Facts



Grades 4 and up


  • multiplication and division to find missing factors


  • 2 to 4


  • playing cards Ace (=1) through 10
  • paper and pencil


Each player makes a gameboard for their opponent. The gameboard is made up of ten number sentences (math problems) with missing numbers. The missing numbers can be any number 1 through 10.

  • 3 x __ = 27 (the missing number is 9)
  • __ x 6 = 42 (the missing number is 7)
  • 2 x __ = 18 (the missing number is 9)

Players take turns flipping over a card from the deck. They try to use each number to help them complete one of the number sentences their opponent created. If a player turns over a card that cannot be used, that turn is missed. The first player to complete the gameboard their opponent created is the winner of the game.

Joanne Currah and Jane Felling have created two best-selling math game books -- Shuffling Into Math (for teachers of grades K-3) and All Hands on Deck (grades 1-9). Each book includes simple instructions for more than 100 math games that help children discover math concepts and reinforce math skills. Education World is pleased to present a selection of those activities in this series.
