"My students are always thrilled when I pull out a math mystery for them! I love how they are aligned from one grade level to the next."

"I love using this as a review when we are in our multiplication unit because students love to act as they can only do one hard thing in math at a time, so this reminds them that they are still perfectly capable of having the brain capacity to do both!"

Description

In this Subtraction Math Mystery Activity – Case of The Dream Snatcher (GRADE 4) – students will practice subtraction skills (with larger numbers) to solve this mystery nightmare! This fun and engaging math activity will motivate your students during math class.

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!

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

Preparation

- Print the student pages, staple or place 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.

- Digital option: Make digital copies of the Google Slides before assigning them to Google Classroom

- Editable hideouts list included: This enables you to change the location names and alter the mystery outcome. Two alternative pre-made lists are also included for a quick swap out.

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

Math Skills Required to Unlock Clues

There are five clues to crack to solve the mystery:

Clue 1: Subtracting 3-digit, 4-digit and 5-digit numbers

Clue 2: Subtracting 4-digit, 5-digit, and 6-digit numbers

Clue 3: Subtraction Word Problems (3-digit, 4-digit and 5-digit numbers)

Clue 4: Subtraction Input/Output Tables

Clue 5: Subtraction of 4-digit, 5-digit, and 6-digit numbers

Students must use critical thinking skills to determine what the clue is telling them to eliminate from the list of possibilities.

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

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, move on to the next clue 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?

The 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.
