Work Place Instructions 2D Doubles Help

Each pair of players needs:

  • 1 spinner overlay to share
  • their own 2D Doubles Help Record Sheets

1. Players work together to complete the Doubles facts in the bottom row on the record sheet.
2. Players take turns spinning the second spinner. The player with the higher spin goes first.
3. The first player spins both spinners to make a multiplication fact.
4. The player solves the multiplication fact and writes an equation for that fact in the column on the record sheet that shows the Doubles fact that can be used to solve it.
For example, if a player spins 3 × 7, they can write an equation for this fact in the 2 × 7 column, because you can use 2 × 7 plus another 7 to solve 3 × 7.
5. Players take turns until one player has written at least one equation in each column.

  • If a player spins a fact for a second time, they write an equation for that fact beneath the column.
  • Players can write more than one equation in each column by spinning different facts that can be solved using the same Doubles fact to help.
  • Writing more than one fact in each column does not improve a player’s chance of winning.

6. The first player to write at least one equation in each column wins.
If players run out of time before someone writes an equation in each column, the player with equations in the most columns wins.

5 × _____ = 35 9 + ____ = 16 ____ + 13 = 20 9 + ___ = 20
8 × ____ = 56 49 = ___ × 7 18 – ___ = 8 7 = 16 – ____
Answer:
The given Equations are solved and the missing number is placed in the given blank as shown below.
4 × 8 = 32  15 = 9 + 6   8 = 12 – 4   14 – 8 = 6
5 × 7 = 35   9 + 7 = 16   7 + 13 = 20   9 + 11 = 20
8 × 7 = 56   49 = 7 × 7  18 – 10 = 8   7 = 16 – 9
