Estimating Square Roots - Notes, Practice Problems and Key

Are your kids having trouble estimating square roots? Are they intimidated by the radical symbol? These notes are written in a simple colorful way that will hold your students' attention and show them how easy this process actually is. This is a topic covered on state tests.

I would suggest handing out the notes to each student in addition to going over the process on the board.

*Helpful hint: I easily turned this into a "game" called "Name That Square Root! " . (Little did the kids know that I was just talking in a more cheesy voice and they were actually just doing math :) )

Possible activity to do with your class - Write down all of the perfect squares up to 225 on the board. Hand out square roots on note cards at the start of class. Have your students place the notecards between the correct two numbers on the board. It helps them visualize the location and also gets them out of their seats!
