$4.50 USD

Looking for a no-prep way to reinforce decimal operations with your students? Alien Invasion is a CSI Math Mystery that blends 5th grade math review with a fun detective theme. Students solve puzzles involving adding, subtracting, multiplying, and rounding decimals to the hundredths to eliminate suspects and save Earth from the alien threat.

This printable escape-style activity is perfect for use in math centers, spiral review, test prep, or homeschool enrichment. Students love the storyline, and teachers love the critical thinking and fluency practice built into every page.

What’s Included:

  • Addition and subtraction of decimals

  • Multiplying decimals

  • Rounding to the nearest hundredth

  • Suspect list with puzzle-style worksheets

  • Full answer key

  • Color and black-and-white printable versions

Math Mysteries are independent escape room or crack-the-code types of fun math activities where students identify suspects using puzzles and word problems instead of locks. This Alien Invasion edition is great for year-round decimal review, from back-to-school through summer learning.
