Common Core State Standards

 Math Math 3 Grade 3 MD Measurement & Data C Geometric measurement: understand concepts of area and relate area to multiplication and to addition 7b Relate area to the operations of multiplication and addition. a. Find the area of a rectangle with whole-number side lengths by tiling it, and show that the area is the same as would be found by multiplying the side lengths. b. Multiply side lengths to find areas of rectangles with whole-number side lengths in the context of solving real world and mathematical problems, and represent whole-number products as rectangular areas in mathematical reasoning. c. Use tiling to show in a concrete case that the area of a rectangle with whole-number side lengths a and b + c is the sum of a × b and a × c. Use area models to represent the distributive property in mathematical reasoning. d. Recognize area as additive. Find areas of rectilinear figures by decomposing them into non-overlapping rectangles and adding the areas of the non-overlapping parts, applying this technique to solve real world problems.

Questions to Consider
Why does Ms. Park go back to 3rd grade content standards? How does she ramp up to teaching 6th grade content?When Ms. Park says that you create your practice by knowing the content first, what does this mean?How does Ms. Park ask students to reflect on their learning? Why is this reflection important?
