Product Description

This Christmas Math Mystery, the 'Case of the Selfish Elf' (4th Grade Edition) will add an exciting twist to your math sessions. NO PREP Required!

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

There is an optional Video Hook available to introduce this activity to your students in a fun way

Students must use their math skills to eliminate suspects so they can find out who is the Selfish Elf?

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

Preparation

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

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

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: Subtracting Fractions with Like Denominators (no reducing)

Clue 2: Addition and Subtraction Algorithms (3 and 4-digit numbers)

Clue 3: Convert Mixed Number Fractions to Improper Fractions

Clue 4: Dividing Numbers Ending in Zeroes (Long division format. 3-Digit Numbers by 1-Digit Numbers. NO Remainders)

Clue 5: Multiplying Numbers Ending in Zeroes (2 and 3-Digit numbers by 1-Digit numbers. Vertical Algorithm Format)

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.

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, as well as 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.
