Description

The Decimal Deceiver is on the loose and the Mathematical Security Agency needs your 5th grade students’ help to catch him! Anyone with an internet connection and device can complete this fun online math activity. This escape room style challenge is fully automated using a Google Form™. Teachers and students DO NOT need to have Google™ accounts in order to complete the tasks. The answer key provides hints to give students if they are stuck. Teachers will have two options to choose from when assigning this escape room to students. Most of the puzzles are the same, however Option B offers one additional puzzle along with a more challenging final puzzle. This option is great for kids who need an extra challenge!

This online breakout has been updated to include instructions and tools for implementation for distance learning. This math activity can also be used by homeschoolers or for math tutoring sessions.

5th grade math activity Place Value and Decimals

This escape room was specifically designed for fifth grade, but could be used by other grades. To successfully complete the challenges, students need to be able to:

• Recognize that in a multi-digit number, a digit in one place represents 10 times as much as it represents in the place to its right and 1/10 of what it represents in the place to its left (5.NBT.A.1:) Example of clue type: The digit 2 in the code has a value that is 100 times greater than the digit 2 in 367.25
• Write a number in standard form that is written in expanded form (to the hundredths place).
• Multiply a number with decimals up to the hundredths place by a single digit. Example: $1.57 x 4
• Calculate change by subtracting numbers with decimals to the hundredths place.
• Multiply decimals by powers of ten. Example 5.23 x 10^4 (ten to the fourth power).
• Compare decimal numbers to the hundredths place using <, >, and = symbols.
• Round numbers that include decimals to the thousandths place.

This activity can be done in small groups or individually. It can be used for review, a fun challenge, an extra activity for early finishers, or even as homework.
