Description

This New Year's Math Mystery, the 'Case of the Millennium Bug' - 2nd Grade Edition - will add an exciting twist to your math sessions. This activity will engage and motivate your students to get back into their math work after the holiday break!

Easy prep! Just Print & Solve! Or go paperless with the new Google Slides option provided within your download.

Optional video hook included for introducing the case! (Check it out in the preview section)

BONUS: Ending video added to wrap up the case!


Students must use their math skills to eliminate suspects to find out who the New Year Hacker is!

--------------------------------------------------------------------------------------------

Preparation

- No Prep required! Print the student pages, staple or place

them in a folder, and your students are set to go.

- Have the video hook ready for viewing at the start of the

lesson on an IWB, iPad, or computer monitor screen.

-----------------------------------------------------------------------------------------------

Math Skills Required to Unlock Clues

There are five clues to crack to solve the mystery:

  • CLUE 1: Choose the Appropriate Length Unit (Estimate Lengths) Customary and Metric Options provided.
  • CLUE 2: Odd Numbers
  • CLUE 3: Addition (with some regrouping, mostly 2-digit numbers with the introduction of a few 3-digit numbers at the end)
  • CLUE 4: Adding Multiples of 10 and 100
  • CLUE 5: Comparing numbers (1 - 3 digit numbers)

Students must use critical thinking skills to figure out what the clue is telling them to eliminate from the list of elf suspects.

----------------------------------------------------------------------------------------------

Multiple Uses

- Suitable for independent, pairs, or group work.

- Use as part of your math centers, add to your sub tubs, make it part of your early finisher tasks, give for homework, or make it part of your classroom practice/review sessions.

I recommend pacing this activity by giving students one clue at a time. Once the whole class has completed a clue, then move on to the next clue, either within the same lesson or the next math session. New math content presented? Make a lesson out of it by modeling the math before diving into the clue. I like to say, "We must learn something new before attempting the next clue."

-----------------------------------------------------------------------------------------------

How long will this activity take?

Time to complete will vary anywhere between 30mins - 2 hours or more! It mainly depends on how familiar your students are with the math mystery format and how difficult they find math skills covered in the particular mystery. Please check the math skills outlined in the clues above to help determine suitability for your class.
