Do your students need some more practice estimating square roots, but they’re sick of completing problems from a traditional worksheet? Are they constantly checking out because they’re bored?

Enter the estimating square roots digital mystery picture (for Google Sheets™), a fun and engaging way for students to identify the two consecutive integers between which the positive or negative square root of a given number lies. Learners will be motivated to complete each question in this activity so that they can reveal the mystery image.

How It Works:

Students will answer 20 questions that ask them to determine the two consecutive integers between which the square root of a given number lies (note: square roots are both positive and negative). They then enter their answers into the appropriate cells on their Google Sheet™.  

Correct answers will turn green, and pieces of the mystery image will appear. Incorrect answers will remain yellow, and no part of the image will reveal. When their answers are wrong, students should go back and try again!
