Need a low prep activity to keep students engaged this Halloween? Just add this resource (and maybe some candy)! This quick and fun game has students practice approximating square roots to the nearest whole number.

How it works:

In this Halloween activity, students take turns answering 16 questions. You can have them play individually or in pairs. Each problem is a square root of a non-perfect square in which students need to estimate to the closest whole number. Students will choose between two answer choices and lift the flap.

  • If the flap reveals "treat," they got the answer correct.
  • If the flap reveals "trick," they got the answer wrong.

This Halloween activity is engaging because students are up out of their seats and playing a game. You can even include real treats when students get the answer correct to make it even more engaging!

This resource requires minimal prep! Simply print enough of each answer sheet and tape the question to the front.

I like to use this game as part of stations or for early finishers.

I hope you love it and your students learn it!

to see state-specific standards (only available in the US).
Use rational approximations of irrational numbers to compare the size of irrational numbers, locate them approximately on a number line diagram, and estimate the value of expressions (e.g., π²). For example, by truncating the decimal expansion of √2, show that √2 is between 1 and 2, then between 1.4 and 1.5, and explain how to continue on to get better approximations.
