PRODUCT DESCRIPTION

This product targets three Common Core standards. The main lesson includes 12 problems. Students plot and connect points on the coordinate axes. Then students find the area of the shapes they create. The lesson has a nice progression from simple rectangles and triangles to irregular polygons that must be decomposed into rectangles and triangles.
If you are looking for a lesson that combines many skills, then this is a great resource for you. Students plot ordered pairs in all 4 quadrants. Students find the distance between points. Students find area of shapes by decomposing the shapes into rectangles and triangles. The answer key is in PowerPoint with great visuals to show students how to decompose irregular polygons into rectangles and triangles.
This product also includes a warm up activity (5 problems) to review area of rectangles and triangles (on a grid/first quadrant).
