"This was a great resource for my students, and even better for a math assignment when you need a planned or non-planned sub day. It was a little tricky for some of my students, but they were able to work through it."

Description

This 4th Grade Winter Math Mystery activity will motivate your students to solve the clues to stop Waldo, the Warlock's, rising Snowman Army! 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!

Distance Learning Update: I've added a Word Document within the folder that contains a Google Slides link to share this resource with your students via Google Classroom or Drive. Parts of the pages are editable so your students can complete them without printing them. Please note that you will need to make a copy of the Google Slides to your drive before you can edit.

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

Preparation

- 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.

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

- Editable locations list included: This enables you to change the place 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

Students must use their math skills to unlock clues that will he;p them find the Ice Queen!

There are five clues to crack to solve the mystery:

  • Clue 1: Multiply Numbers Ending in Zeroes (2-digit numbers by 2-digit numbers, both ending in zeroes)
  • Clue 2: Convert Time Units
  • Clue 3: Equivalent Fractions (Fill in the missing numerator to make a pair of fractions equivalent)
  • Clue 4: Rounding (Hundreds, Thousands, Ten Thousands, Hundred Thousands)
  • Clue 5: Continuing Patterns

>> Pack includes a mystery declaration sheet, answer sheets, an elimination guide, and printable awards.

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

How long will this activity take?

The time to complete will vary anywhere between 30mins - 2 hours! 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. 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." There are lots of ways to implement this activity in your classroom; learn more in the blog post link below:

Use place value understanding to round multi-digit whole numbers to any place.
Multiply or divide to solve word problems involving multiplicative comparison, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem, distinguishing multiplicative comparison from additive comparison.
