Find the area of right triangles, other triangles, special quadrilaterals, and polygons by composing into rectangles or decomposing into triangles and other shapes; know and apply these techniques in the context of solving real-world and mathematical problems. Targeted SkillsFind the areas of polygons using reasoning strategies such as decomposing, decomposing and rearranging, and subtracting. Explain a chosen strategy. Deepen understanding of the definition of area.

In this lesson, students pivot to learning about and applying the Pythagorean Theorem and its converse to prove that given triangles with side lengths are or are not right triangles. PowerPoint Presentation available.

A comprehensive lesson or mini-lesson on finding the area and surface area of right triangles, other triangles, special quadrilaterals, and polygons by composing into rectangles or decomposing into triangles and other shapes; know and apply these techniques in the context of solving real-world and mathematical problems. Includes warm-ups, cool-down activities, and a lot of interactive practice for students. New IdeasIf two figures can be placed one on top of the other so that they match up exac

Use variables to represent numbers and write expressions when solving a real-world or mathematical problem; understand that a variable can represent an unknown number, or, depending on the purpose at hand, any number in a specified set. Learning TargetsI can use a diagram of a rectangle split into two smaller rectangles to write different expressions representing its area. I can use the distributive property to help do computations in my head.
