# Square Roots

\$0.00

The lesson introduces students to square roots. Students should already be familiar with how to square numbers before working on this lesson. After explaining what a square root is, the lesson defines vocabulary related to square roots such as inverse, radical and radicand. Next the lesson walks through the process for finding the square root. Negative square roots are briefly covered. A chart of perfect square roots is also provided for reference.

### Description

The lesson introduces students to square roots. Students should already be familiar with how to square numbers before working on this lesson. After explaining what a square root is, the lesson defines vocabulary related to square roots such as inverse, radical and radicand. Next the lesson walks through the process for finding the square root. Negative square roots are briefly covered. A chart of perfect square roots is also provided for reference.

Sample Classroom Procedure / Teacher Instruction:

1. Begin by explaining to students that they are going to learn how to take the square root of a number and about a new symbol used by mathematicians.
2. While reading the content pages, reinforce vocabulary and give students additional examples of square root problems in order to help them practice the new algorithm. Use the additional resources to enhance understanding.
3. Introduce the notes on square roots. Have students practice problems with whole number answers.  Use the additional resources to enhance understanding.
4. Have students practice drawing the radical symbol.
5. Follow Activity page with students. Have students work individually but go through the activity together as a large class.
6. Distribute Practice page. Check and review the students’ responses as a class.
7. Distribute the Homework page. Have students work a few problems at the beginning of the next class to reinforce the algorithm.
8. In closing, ask students to explain how the area and the length of a side of a square are related to taking the square root of a number.
9. Allow for responses and discussion.
