30 game boards to use when practicing the doubles plus one strategy with single and double-digit numbers.
Use these Doubles Plus 1 Game Boards when learning about near doubles.
Some suggestions on how to use these game boards in the classroom have been included.
- In groups, provide a game board to each student and 2 dice. Each player takes a turn to roll the 2
dice. The player is then required to add the 2 dice together, double the total, and then add one. If
any of the players have that number on their game board, they can cover it with a marker. Decide
before the game if they need to cover a line vertically, horizontally, diagonally, or all of the numbers to
win the game.
- In pairs, provide 1 game board, 2 dice, and 2 different colored markers. 1 player rolls the 2 dice, then adds
them together, doubles the total, and adds one. If the answer is available on the game board, they
can place their marker on it. If the other player has already covered the answer, they can remove their
opponent’s marker and replace it with their own. When all of the numbers have been covered, the
winner is the player with the most numbers covered.
- Provide each student with 1 of the blank game boards. Have students fill in their game board with all
of the possible answers and then either roll 1 die or use number cards to add together, double, and
then add 1.
Common Core Curriculum alignment
Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - ...
Fluently add and subtract within 20 using mental strategies. By end of Grade 2, know from memory all sums of two one-digit numbers.
