Write & Wipe Fact Family Boards

This simple tool is a great asset when teaching beginning math facts. It's a triangular white board with three 10" sides. It's double sided and has a write-and-wipe surface that works with any dry-erase marker (not included). Displayed on one side are four simple equations with the numbers left blank (two of __+__=__ and two of __-__ =__ ). The corners of the triangle are shaded different colors and teachers can write variables in the three corners and have students plug them in appropriately. For example, if 10, 7, and 3 were written in the corners, students could write 7+3=10, 3+7=10, 10-7=3, and 10-3=7. The opposite side of the board is identical but displays multiplication and division signs instead of addition and subtraction. With such an open-ended format and a reusable surface, this board is sure to get plenty of use.
