Story

You have been having fun all summer. Your family has gone on a vacation to your favorite spot, you have had lots of fun with your friends, and you have had plenty of trips to both the swimming pools and the beach. But then one day when you wake up ready to enjoy another fantastic day it is gone!

Who has stolen summer? You look out the window for signs of it, but it is not there. You run downstairs to ask your mom, but she does not know. You quickly get dressed so you can investigate.

It is up to you to solve the case and find out who has stolen summer. Solve the clues to narrow down your suspects and discover who the villain is.

This detective case includes:

• Subtraction from 100 of 2 digit numbers
• 3-digit addition with regrouping
• Addition and subtraction with 3 digits
• Multi digit addition
• Addition and subtraction word problems

Includes color and black and white versions

These math mysteries are designed for 2nd, 3rd and 4th grade students. Could also be used with struggling 5th grade students that need a little extra work and reinforcement in adding and take aways (or advanced, gifted and talented 2nd grade). I also leave some of the mysteries for my sub teacher and use the as a math review.

Math Mysteries are an independent escape room or crack the code type of fun math activity where instead of using locks, students identify suspects with puzzles and word problems. This mystery is perfect for the start of year with back to school activities.
