## Reflection: Adjustments to Practice Designing the Perfect Floor Plan: Showing Understanding of Area and Perimeter - Section 2: Connection to Real Life: Looking at a Floorplan

One student asked if we should use area model to multiply. I used this moment to connect this multiplication strategy to area and help them understand that each number represented a length and width, (sort of) without units. It was the same concept with different meaning. I heard one student say "OHHHHHH!" and could see that the whole concept of area must have all of a sudden clicked! These "aha" moments are what I live for.  Prior to teaching CCSS, I would not have worked that hard to help students make these kinds of connections and I was more focused on just getting them to memorize the formulas. I think the connection to the real world, looking at jobs and floor plans of houses makes the formulas have meaning.

In the past, prior to CCSS, I would have just used the text book and the drawings that would be offered in the lesson. The real world connection that MP 4 encourages helped students connect prior knowledge of arrays. So, getting myself out of that text book and transferring it to real life resources makes it all more meaningful.
