Knowledge

Students know:

Area is a measurable attribute of two-dimensional figures.
The area measurement of rectangular regions has a multiplicative relationship of the number of square units in a row and the number of rows.

Skills

Students are able to:

Decompose rectilinear figures as non-overlapping rectangles using concrete materials.
Find the area of two rectangles, and create a rectilinear figure by joining the two rectangles (without overlapping), and determine the area of the created rectilinear figure as the sum of the two rectangles.

Understanding

Students understand that:

rectilinear shapes can be decomposed into non overlapping rectangles, and the sum of the areas of the nonverlapping rectangles is equivalent to the area of the original rectilinear shape.
