In this mystery, students will learn that the big basket of tennis balls for the Taylor tennis team has been stolen. No one knows who took them! Students will complete four subtraction fact challenges and earn clues to solve the mystery!
Whether you’re teaching in the classroom or teaching virtually, I’ve got you covered! For teachers in the classroom, everything can be easily printed and assigned to students. I’ve included black & white ink-friendly options, too. For teachers teaching virtually, this resource has also been converted to Google Slides and Seesaw, so you can assign everything remotely!
I suggest using this resource over the course of one week. This will give your students Monday through Thursday to complete all challenges (one to two per day), and then on Friday students can sift through the clues to solve the mystery. If you have time or want to plan an extra engaging day, you could also make an entire morning and/or afternoon of the whole thing and do it all at once! *Please note that doing the entire mystery in one day will take more than you probably have allotted during your math time!
