My students love these number puzzles. They are a great way to practice different strategies for adding and subtracting two-digit and three-digit numbers. They help students play with decomposing numbers to build addition and subtraction math strategies for second grade.
A game for 2 or 3 players. Each player chooses a color pencil they will use in the game. Players take turns rolling the dice, using the numbers that they rolled to draw the perimeter of a rectangle or square & writing the area in the middle of the shape. Game ends when players run out of room to draw. Winner is the player who has used the largest area/most squares.
