# Decimal Escape Activity

This decimal escape activity is a math lesson your students won’t forget. To be over-the-top cheesy, some might say it’s out of this world!

In the decimal escape, students must work together to escape from outer space. To escape, students unlock a series of locks to acquire the extra fuel from the international space station. There are multiple versions of this activity to meet various classroom needs.

• One version is for a physical set-up of the activity that uses locks and boxes.
• The second version is for a hybrid digital version of the activity that does not require boxes or locks. Instead, students will enter the codes on their device through Google Forms. They use a printed version of the actual activities.
• The third version is completely digital where students solve the problems on Google Slides and enter the codes in Google Forms.

## Decimal Escape-Clue 1

Students match each rocket with the corresponding astronaut. After they match the rockets with the astronauts, they will line the cards up from least to greatest. After students arrage the cards correctly, they will be able to read the clue that tells them the code to the first lock.

## Clue 2

In the second part of the decimal escape activity, students determine which decimal is the largest decimal through a bracket system. They will compare each set of decimals on the bracket and record the largest decimal. Students continue until there is ONE decimal. The digits of that decimal will unlock the 4-digit lock. Your sports enthusiast will love this one!

## Decimal Escape-Clue 3

Students use symbols to compare each set of decimals. The record how many of each symbol used on the recording sheet. This will give students the code for the lock. There is definitely an emphasis on comparing decimals in this escape.

## Clue 4

Students solve each of the decimal fraction problems. They use the key at the bottom of the page to determine the five colors on the five color lock. This clue will give students the final code, so they can make it home!

As with all my escape room activities, there are detailed teacher directions for easy set-up and prep.
