Geometric Measurement: Understand Concepts Of Area And Relate Area To Multiplication And To Addition.
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.

Measurement And Data
Geometric Measurement: Understand Concepts Of Area And Relate Area To Multiplication And To Addition.
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.
