I was hunting through some old material for some new ideas to share with you, and have I got a winner! About 15 years ago I did a workshop called “The Idea Factory” and included a math game called MORE, LESS, EQUAL. I guess this just goes to show you that everything old is new again because this is a perfect activity for Common Core!
Divide children into partners and give them manipulatives and a sack with three index cards on which you have written “greater than,” “less than,” and “equal.” One child makes a set with the manipulatives. The second child draws a card from the bag and then makes a set according to the directions on the card.
SQUISH is a similar game that can be played with play dough. One child squishes the dough and makes a set. The second child selects a card and then must squish the play dough to make a set “greater,” “less than,” or “equal.”
Hint! I think it would be good for the teacher to model this game with students before dividing them up with a partner.
