This activity is a fun way for students to review topics covered in the 7th grade expressions & equations unit. Students will have to complete 8 challenging tasks that will all lead to them finding codes to save their school from a mad scientist! This escape room is completely digital and created for google drive!

**Topics Covered**:

- Task A: Solving Two-Step Equations
- Task B: Writing and Solving Two-Step Equations from Real World Problems
- Task C: Simplifying Linear Expressions with Factoring
- Task D: Simplifying Algebraic Expressions with Rational Numbers
- Task E: Solving Two-Step Inequalities
- Task F: Solving & Graphing Two-Step Inequalities on a Number Line
- Task G: Writing and Solving Two-Step Inequalities from Real World Problems

All the tasks in the activity are independent of one another so you can pick and choose which tasks to give your students or give them all the tasks (one at a time) for a full review of the unit.

CCSS7.EE.B.4b

Solve word problems leading to inequalities of the form π±πΉ + π² > π³ or π±πΉ + π² < π³, where π±, π², and π³ are specific rational numbers. Graph the solution set of the inequality and interpret it in the context of the problem. For example: As a salesperson, you are paid $50 per week plus $3 per sale. This week you want your pay to be at least $100. Write an inequality for the number of sales you need to make, and describe the solutions.

CCSS7.EE.B.4a

Solve word problems leading to equations of the form π±πΉ + π² = π³ and π±(πΉ + π²) = π³, where π±, π², and π³ are specific rational numbers. Solve equations of these forms fluently. Compare an algebraic solution to an arithmetic solution, identifying the sequence of the operations used in each approach. For example, the perimeter of a rectangle is 54 cm. Its length is 6 cm. What is its width?

CCSS7.EE.B.4

Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities.

CCSS7.EE.B.3

Solve multi-step real-life and mathematical problems posed with positive and negative rational numbers in any form (whole numbers, fractions, and decimals), using tools strategically. Apply properties of operations to calculate with numbers in any form; convert between forms as appropriate; and assess the reasonableness of answers using mental computation and estimation strategies. For example: If a woman making $25 an hour gets a 10% raise, she will make an additional 1/10 of her salary an hour, or $2.50, for a new salary of $27.50. If you want to place a towel bar 9 3/4 inches long in the center of a door that is 27 1/2 inches wide, you will need to place the bar about 9 inches from each edge; this estimate can be used as a check on the exact computation.

CCSS7.EE.A.2

Understand that rewriting an expression in different forms in a problem context can shed light on the problem and how the quantities in it are related. For example, π’ + 0.05π’ = 1.05π’ means that βincrease by 5%β is the same as βmultiply by 1.05.β
