Decomposing and Composing Shapes: Math 3 | Classroom Connection | Grades 3-5 Sharing Attributes Across Shapes (Grade 3) Teaching and Lesson ResourcesHave you ever put a rhombus on top of a trapezoid? This Classroom Connection lesson will show you how to break down and combine shapes to make new ones.

Calculating Rectangular Area | Cyberchase | Grades 3-5 Composing and Decomposing to Find Area of Triangles, Quadrilaterals, and Polygons (Grade 6) Teaching and Lesson ResourcesIn this video segment from Cyberchase, the CyberSquad must measure two differently-shaped parcels of land to determine which has a larger area. The CyberSquad uses tarps, fence posts, and finally a grid made out of rope to count squares and determine the area of each parcel.

Area of a Trapezoid | Grades 6-8 Composing and Decomposing to Find Area of Triangles, Quadrilaterals, and Polygons (Grade 6) Teaching and Lesson ResourcesLearn about the characteristics of a trapezoid and how to find its area in this video from KCPT. In the accompanying classroom activity, students develop the formula for the area of a trapezoid by decomposing it into smaller, more familiar shapes.

Area of a Parallelogram | Grades 6-8 Composing and Decomposing to Find Area of Triangles, Quadrilaterals, and Polygons (Grade 6) Teaching and Lesson ResourcesLearn about the characteristics of a parallelogram and how to find its area in this video from KCPT. In the accompanying classroom activity, students develop and apply the formula for the area of a parallelogram.

Formulas: Area of a Rectangle | Grades 9-12, 13+ Geometric Measurement: Area, Multiplication, and Division Teaching and Lesson ResourcesThis video explains how to calculate area. Area is the measure of the surface inside a flat figure. Area is measured in square units. Multiply the length times the width to get the square units. This video segment is from the GED Connection Formulas video.

Area of a Triangle: Relation to Rectangles | Grades 3-5, 6-8 Composing and Decomposing to Find Area of Triangles, Quadrilaterals, and Polygons (Grade 6) Teaching and Lesson ResourcesExplore the relationships between the area equations for rectangles and triangles. This video focuses on modeling the area equations for a rectangle and triangle and talks how base and height differ from length and width. This video was submitted through the Innovation Math Challenge, a contest open to professional and nonprofessional producers.
