Even and Odd Rules of Operations Game: double dice

6. Even & Odd Outcomes Game
To Play…
Use a sheet of scratch paper, the double dice, a pencil, find a partner.
Use the data sheet to tally how many even and odd sums come up when you roll the double dice 10 times.

7. Even & Odd Outcomes
Knowing the even and odd rules of computation helps students to reason mathematically.
There are only 4 outcomes when adding:
 even + even = even (2 + 4 = 6)
even + odd = odd (2 + 3 = 5)
odd + even = odd (5 + 2 = 7)
odd + odd = even (3 + 5 = 8)

8. The Game of Even and Odd Outcomes for Multiplication
There are only 4 outcomes when you multiply numbers:
even x even = even (4 x 2 = 8)
even x odd = even (6 x 3 = 18)
odd x even = even (5 x 4 = 20)
odd x odd = odd (3 x 5 = 15)
