Practice addition and subtraction of rational numbers in an engaging digital escape room! Students will race to match equivalent expressions involving adding and subtracting positive and negative numbers, figure out the signs of sums and differences of decimals or fractions on a number line, solve word problems, find the distance between points using knowledge of absolute value, and much more to save a submarine that has been sabotaged. Based on seventh grade standard 7.NS.A.1, this online breakout as an easy to use, no prep, self-checking way to review material or practice for a test. This is a fun worksheet alternative that can be used for both in-class or distance learning.

Escape rooms are great for encouraging collaboration among students and an excellent way to get kids engaged in learning. This digital breakout gives students the opportunity to use their knowledge to solve puzzles using addition and subtraction of rational numbers as they follow a story line and save the submarine from sabotage.

Skills required to complete the puzzles:

• Add and subtract integers, and rational numbers including simple fractions and decimals
• Calculate the distance between a positive and a negative number (one method would be to find the absolute value of their differences)
• Use a number line to aie in addition and subtraction of positive and negative rational numbers
• Solve word problems involving adding and subtracting positive and negative rational numbers
• Match equivalent expressions to demonstrate understanding of subtraction as adding the additive inverse and other addition and subtraction rules that apply to negative numbers

FAQ

• Do students need to have Gmail™ accounts? NO! Anyone with internet access and a tablet, computer, or even phone can complete the breakout. The escape room is automated by a Google Form™, but does not require the teacher or students to have Google™ accounts.
• How long will this take? That is the hardest question as the answer varies depending on each classroom, student, or group. Some students with a firm grasp on the concepts covered in this escape room will be able to complete the challenge very quickly (20 minutes), others will take longer. The majority of students will take between 35-45 minutes. Requiring students to use the recording form will increase the amount of time required to complete the puzzles. The form will not save student data, so if you are worried about your students not finishing on time, simply have them write their answers on scratch paper. They can then come back and quickly re-enter their answers and pick up where they left off.
• Will students have to search the web to figure out the puzzles? NO! All of the information needed will be provided in the Google Form™. The math in this activity is all standards-based.

*Please make sure that your school district does not block Google Forms™. There is the option to create your own copy of the form for schools that require Google Forms™ to originate from within their system.
