In this Montessori -inspired pumpkin pie-themed addition activity, students use the movable tiles provided to make a number 1 less than the number displayed. This Fall / Halloween activity is self-checking as all good Montessori-inspired materials should be. It contains 5 puzzles each with 10 addition problems in a fun pumpkin-pie themed array. Students know they have the answer correct when there are no tiles left on the board. This activity is the first in a series that I call "More Than Before".
