Dinosaur week: Fun & Simple dinosaur activity for kids! Maybe for older kids give each shape a numerical value and have them add how much their dino is worth. Can use with class to compare/contrast amounts, etc.
Dots & Boxes for the smart board. Students take turns connecting the dots on a grid to "capture" squares. You can play the classic game; or you can also practice addition and multiplication skills with our two other versions of the game!
