This “upside down” hundred board is just what students need to develop number sense and see how our number system works with our algorithms! I developed this board to help students connect what they hear with what they see.
This board starts with 1 in the lower left corner. It allows students to move up the board as they count higher or add. They subtract and move down the board, more in line with algorithmic directions.
My "different" Hundred Board, directions for use, and sample activities with answers are included.
