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 identifying functions in multiple representations.

How it works:

In this Halloween activity, students take turns answering 22 questions. You can have them play individually or in pairs. Each problem has students determine if the relationship is a function or not a function. Students will choose between "function" or "not a function" and lift the flap.

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

Students must identify a function in

  • a graph
  • a table
  • a set of ordered pairs
  • an equation
  • a mapping diagram

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.

Understand that a function from one set (called the domain) to another set (called the range) assigns to each element of the domain exactly one element of the range. If ๐˜ง is a function and ๐˜น is an element of its domain, then ๐˜ง(๐˜น) denotes the output of ๐˜ง corresponding to the input ๐˜น. The graph of ๐˜ง is the graph of the equation ๐˜บ = ๐˜ง(๐˜น).
Understand that a function is a rule that assigns to each input exactly one output. The graph of a function is the set of ordered pairs consisting of an input and the corresponding output.
