Introduction to lesson:
This lesson will introduce your students to basic subtraction facts from a totally different perspective. No need to memorize 100 subtraction facts, 50 to 55 are all you need to know. This lesson will give your students a visual and conceptual understanding of subtraction. Ten frames are a great tool to help students gain number sense, a conceptual and a visual understanding as to what subtraction really is. You may even wish to consider exploring other number frames to see how they could be used in the same manner to subtract in other number bases and how the same conceptual ideas hold true in all number base numeration systems.
