This morning, Libby began by completing adding 3 fast facts problems. Then, we reviewed the concept of subtracting all or zero. Libby used pictures to complete subtraction sentences by filling in the amounts to show taking away all or nothing, and she completed subtraction sentences by filling in the missing parts. Next, we started the lesson on taking apart numbers. We used different colored crayons to color cube trains, modeling the different ways to show taking apart.
