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

This lesson includes Google slides that cover Illustrative Math Unit 2 Lessons 4 - 12. They may be used in any classroom for learning skills related to scaled copies and scaled drawings. Use the Nearpod add-on to make these slides interactive for face-to-face learning or distance learning. Students will be able to: Use corresponding distances and corresponding angles to tell whether one figure is a scaled copy of another. Describe the effect on a scaled copy when I use a scale factor that is gr

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.

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.

The study guide allows students to practice content connected to 6th curriculum benchmarks and standards.

Activity #1: Post an original and appropriate PEMDAS sentence (like Please Excuse your Dear Aunt Sally) our Google Classroom stream. Activity #2:Order Matters – Puzzle Greeting Activity #3:Discuss Properties of Real Numbers

In this lesson, apply the Pythagorean Theorem and rules for finding volume of solid figures.

Use Scales to read maps. Students must read each question carefully. Show work on the back of the page or on a separate sheet of paper. Use a calculator to review the final work. Mark the best answer.

Classify the following numbers as rational or irrational. Explain your reasoning.

Students simplify numerical expressions involving rational numbers.

Determine whether the numbers below are rational or irrational. Explain why the number is rational or irrational.
