This math station is called "in and out". The students simply drop a handful of cubes onto the in and out board. They record the number in the circle for the first addend and the cubes outside of the circle as the addend. Then solve the number sentence.
Great math station to practice tallying. Choose a monster card, write the number and draw the tally. FREEBIE--instead of monster tally, i could modify idea and do pumpkin tally or adjust to seasons/concepts being taught for week
