In this simple board game, players compete to conquer the most territory on the board. Each player rolls 2 dice and uses the numbers to draw a rectangle on the grid. For example, if you roll a 6 and a 4, you can draw a rectangle that is 6 squares long and 4 squares wide. Find the area and perimeter of the rectangle and write it inside. Players continue conquering territory until time is up or until they can no longer fit any more rectangles on the board. At the end of the game, players total the areas and perimeters of all their territory and the player with the most territory wins.
Tips for teachers: make copies of the game board for each pair and have them use two different colors to mark their territory. Or, laminate copies of the game board and use different colored dry erase markers for a re-usable option.
Three ways to win: largest area, largest perimeter, or most rectangles!
