The Big Ideas



·         The order of factors does not change the product.
·         Multiplication and division are inverse(opposite) operations.
·         Multiplying by 3 is tripling a number.
·         Multiplying by 4 is doubling a double. (If 2x2=4, then 4x2=8)
·         Multiplying by 6 is doubling x3 facts (If 3x3=9, then 6x3=18)

Games for Practice
All Lined Up (x3, x4)
Spin and Cover (÷4)
Capture (x6)



All Lined Up – Materials needed: Gameboard for each player and one spinner (provided by the teacher), pencil and paperclip.             In this strategy game each player has a number line gameboard with 6 empty boxes. Players take turns spinning numbers and multiplying by 3. They then write their product in one of the six empty boxes; however, the numbers must be placed in correct sequence. For example if a player has filled in 3, 9, and 15 in her first three boxes and has 12 for her next product, she cannot play the 12 and loses her turn.  The first player to fill all six boxes wins. For repeated play, students can draw their own number line of boxes!
Variation #1: Play this game using x4 to find your products!

Spin and Cover – Materials needed: Gameboard and spinner (provided by teacher).  Follow the direction printed on the gameboard!

Capture – Materials needed: Spinner and a set of Capture cards (provided by the teacher), pencil and paperclip.  Follow the directions printed on the spinner sheet.
