Growth Mindset Math Mystery Activity - 1st Grade Edition. Easy prep! Just Print & Solve! Or go paperless with the new Google Slides option provided within your download.

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

This mystery has been tailored to use early in the school year, so the math reviews concepts from the previous grade level to help you assess your students.

Students must use their math skills to unlock clues. Then, use their powers of deduction to narrow down the list of nominees to find the winner! The list is shorter and with profile pictures in the first grade edition.

Suggestion: For this specific mystery, I recommend keeping the possible winners list away from students till the end.


Optional VIDEO HOOK available to use to introduce students to this math mystery activity. CLICK HERE to VIEW Video Hook



- No Prep required! 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.

- Editable Winners list included: This enables you to change the character names and alter the mystery outcome. Two alternative pre-made lists 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: Counting Objects (1-20)

Clue 2: Addition with Pictures (less than 20)

Clue 3: Subtraction with Pictures (less than 20)

Clue 4: Comparing Numbers - Circle the larger number (less than 20)

Clue 5: Comparing Numbers - Circle the smaller number (less than 20)

Students must use critical thinking skills to figure out what the clue is telling them to eliminate from the list of possibilities. Your guidance may be required with younger students.


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, 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.
