Finally, we chew gum at the end. I refer back to the packs of gum throughout our learning about multiplication. By Sheila Handres, Third Grade Teacher I use a set of bowling pins to teach subtraction from 10. After the problem is solved, they switch places. I write on the board the number, or the amount of time, that is to be shown on the tray.
Teams huddle together to arrive at a correct display on the tray.
Points are awarded to each team that has the correct answer.
