Add or Take a Tenth

"Add or Take a Tenth" is an engaging educational game that aims to teach players how to add and subtract tenths in a fun and interactive manner. To play, participants will need a 0 - 9 dice, a decimal board, and counters. The game involves taking turns to roll the dice to generate a number with units and tenths, such as 4.7. Players then decide whether to add 0.1 to their number or subtract 0.1 from it. For example, if you roll a 4.7, you can choose to add 0.1 to cover 4.8 on the decimal board or subtract 0.1 to cover 4.6. The game continues with players aiming to strategically cover the numbers on the board.

The objective of the game is to be the first player to align three counters in a row, which can be achieved horizontally, vertically, or diagonally. An interesting aspect of the game is observing what happens when 0.1 is added to a number that has 9 in the tenths place; this results in an increase in the units place. For instance, adding 0.1 to 3.9 results in 4 (or 4.0). This game also encourages discussion about the connection between whole number addition and subtraction and decimal addition and subtraction, such as how adding 1 to 34 to get 35 is similar to adding 0.1 to 3.4 to get 3.5. "Add or Take a Tenth" not only reinforces mathematical concepts but also promotes critical thinking and strategy among players.
