## Reflection: Checks for Understanding Oranges,Social Studies, Sister Anne and Studying the Whole: An integrated lesson - Section 7: More Practice in division using "Box Method": Keeping the New Skill going strong...

I had overheard one girl talk about how she never thought she would understand how to divide, but the "Box Method" is really easy now. Another student told me that she liked today's lesson and that she gets that the dividend is always the whole that we are dividing. I am hoping that this lesson today affirmed any gray areas in their thinking about the role of the dividend and divisor. I am not seeing the confusion I had in the past.

CCSS is set up so that in depth understanding is the focus. Math Practice Standards expect us to create thinking mathematicians. I have learned that we can never assume they understand fully some of the most basic concepts or what appears to be basic to us because prior to CCSS, we didn't teach that way!  I feel confident they came away with under standing that they whole is what is always divided. The concept should help understanding of decimals.
