Will find areas of rectangular figures by decomposing them into non-overlapping parts in order to solve a real world problem

CPALMS 80 min(s)

In this unit on area, students explore geometric measurement by becoming "Area Architects" in order to learn the concepts of area and relate area to multiplication and addition. In this lesson, students will recognize area as additive. Students will find areas of rectangular figures by decomposing them into non-overlapping parts in order to solve a real world problem. Keywords: area, square units, unit squares, rectangle, side lengths, rectangular, rectilinear, multiplication, multiplying, grid, grid paper, architects, addition, additive, decomposing, nonoverlapping. Students will find areas of rectangular figures by decomposing them into non-overlapping rectangles and adding the areas of the non-overlapping parts in order to solve real world problems.
