Directions: Students will use basic computation skills and/or the Commutative and Associative Properties in order to solve each math puzzle. In each math puzzle, the numbers in each row and column have the same sum. Students must identify the missing numbers in each row, column, and diagonal in order to identify the common sum and solve the puzzle!
Note to Teachers: You will find a sheet of blank puzzles in this set. As a an enrichment activity, you can create multiple copies of this sheet and have students develop their own puzzles for classmates to solve!
Also, an additional way to increase student motivation and incorporate a FUN twist to this activity is to purchase cheap adhesive mustaches from a party store (enough for a class set) and pass these out to students to wear as they solve the puzzles. They look hilarious and the kids have a blast playing the part of “detectives” solving mysteries
