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.

Let’s decompose, compose, and rearrange shapes to find their areas. Created using Nearpod add-on in Google Drive and designed for remote learning or 1:1 classroom. Check for understanding and Cool Down included. Google Form quiz available as well.

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

Digital lesson create with Google Slides and Nearpod add-on. This lesson works well in all classroom structures. Students can use the area formula to find the area of any parallelogram.practice using the formula for the area of parallelograms.I choose the measurements to use as a base and a corresponding height.

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.New IdeasI can identify pairs of base and height of a parallelogram. I can write and explain the formula for the area of a parallelogram. I know what the terms "base" and "height" refer to in a parallelogram.
