Distance Between Two Points Guided Notes w/ Doodles | Pythagorean Theorem Lesson Plan

Overview

Ever wondered how to teach the distance between two points in an engaging way to your eighth-grade students? In this lesson plan, students will learn about the distance formula by applying their knowledge of the Pythagorean Theorem. Through artistic, interactive guided notes, practice activities like a doodle and color by number, and a maze worksheet, students will gain a comprehensive understanding of the topic.

The lesson ends with a real-life example that explores how the distance between two points can be applied to real life situations.

Learning Objectives

After this lesson, students will be able to:

• Find the distance between two ordered pairs (whole number solutions)

• Find the distance between two points on the coordinate plane (whole number solutions)

Prerequisites

Before this lesson, students should be familiar with:

• Understanding of the concept of right triangles

• Knowledge of the definitions of legs and hypotenuse in a right triangle

• Familiarity with the concept of squares and square roots

Key Vocabulary

• Distance Formula

• Legs

• Hypotenuse

• Pythagorean Theorem

Procedure

Introduction

As a hook, ask students why understanding the distance between two points is important in real-life scenarios. Refer to the last page of the guided notes as well as the FAQs below for ideas.

Use the first page of the guided notes to introduce the concept of finding the distance between two points using the Pythagorean Theorem. Students practice solving for the unknown distance (i.e. hypotenuse) when given the vertical and horizontal lengths (i.e legs). Review the definition of the Pythagorean Theorem and vocabulary terms such as legs and hypotenuse. Then, connect the Pythagorean Theorem to the distance formula.

Use the second page of the guided notes to formally introduce the distance formula. Students then practice finding the distance between two ordered pairs and two points on a coordinate plane.

Based on student responses during the introduction, reteach any concepts that students may need extra help with. If there is a wide range of proficiency levels in the class, consider pulling out students for reteaching while having more advanced students begin engaging with the practice exercises.

Practice

Have students practice finding missing distance by apply the distance formula using the maze activity (pg. 3) in the guided notes resource. Encourage students to work collaboratively and discuss their approach to solving the problems.

Fast finishers can engage with the color by number activity (pg. 4) for additional practice. This will reinforce their understanding of the theorem in a fun and creative way. You can assign the Maze activity as homework to consolidate their learning further.

Real-Life Application

Bring the class back together, and introduce the concept of applying the distance formula in real-world scenarios. Discuss how the distance formula is used in fields like GPS and satellites. Refer to the FAQ for more ideas on how to teach real-life applications of the distance formula.
