Hexagon addition and subtraction puzzles. A small hexagon in the middle with a number on it and students have to find the correct sums to go around the little hexagon to make a big hexagon. So many ways to play... - play with a partner to complete the puzzles. - play in small groups with a teacher and each person takes a turn to pull out a sum and place it on the correct hexagon. - bingo: each player picks a number and the teacher/caller picks sums and players place around their hexagon. First to fill their hexagon wins.Great for independent or small group work.
