This code breaker activity will help your students to master quadratic equations. Students must solve 20 equations in order to figure out how to open a safe.

A printable version of the equations is also included.

This is a Google Form activity. There are no links to outside websites. The four parts are set with answer validation: students cannot move to the next part until they solve all the equations.

You can use it as:

★ additional materials for remediation

★ a reward or “Fun Friday” activity

★ before the busy holiday break

★ an emergency sub lesson plan
