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 review and practice 8th grade number system standards and more!

How it works:

In this Halloween activity, students take turns answering 20 questions. You can have them play individually or in pairs. 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.

The questions in this game review:

  • approximating square roots
  • estimating cube roots
  • classifying numbers as rational or irrational
  • comparing real numbers
  • writing a fraction as a repeating decimal
  • scientific notation
  • exponent rules

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. You can play in small groups, at stations, or whole class.

I hope you love it and your students learn it!

Perform operations with numbers expressed in scientific notation, including problems where both decimal and scientific notation are used. Use scientific notation and choose units of appropriate size for measurements of very large or very small quantities (e.g., use millimeters per year for seafloor spreading). Interpret scientific notation that has been generated by technology.
Use numbers expressed in the form of a single digit times an integer power of 10 to estimate very large or very small quantities, and to express how many times as much one is than the other. For example, estimate the population of the United States as 3 × 10⁸ and the population of the world as 7 × 10⁹, and determine that the world population is more than 20 times larger.
Use square root and cube root symbols to represent solutions to equations of the form 𝘹² = 𝘱 and 𝘹³ = 𝘱, where 𝘱 is a positive rational number. Evaluate square roots of small perfect squares and cube roots of small perfect cubes. Know that √2 is irrational.
Know and apply the properties of integer exponents to generate equivalent numerical expressions. For example, 3² × (3⁻⁵) = (3⁻³) = 1/3³ = 1/27.
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.
