First Grade Addition and Subtraction 1 - Beginning Fact Families teaches students how to match a related addition and subtraction sentence using a cowboy round-up theme. They are also taught how to write the related fact. The final word problem introduces the fact family. There is a title slide, focus slide, objective, vocabulary, concept development, demonstration on how to match a fact family member, guided practice, checking for understanding, problem solving with word problem, and a reward slide at the end. For best results, students should have white boards and dry erase markers.
