If there’s one thing I love when creating math projects for 2nd graders, it’s the eager passion for school, puzzles, and solving problems. Even if sometimes the mystery is where did our teacher leave her coffee in the classroom? Not speaking from experience or anything! It’s an all-hands-on-deck situation with everyone helping solve the problem – and it’s usually resolved quite quickly!
It got me thinking… how can I channel this energy my students have into their work? What kinds of projects would be appropriate, relatively challenging, and motivating for my students? Well, since it turns out my students loved finding my missing coffee, I created mystery math projects for them!
Math Projects for 2nd Graders
Each mystery math project or challenge begins with a letter to my 2nd graders explaining some sort of problem or mystery that will need to be solved.

In every mystery math project, students have a series of math challenges (typically completed over a week) to finish in order to earn clues that will help them. Because we have students of varying abilities, each challenge comes in 3 levels so you can differentiate as needed.
Once students have completed all the challenges, they can sift through the clues to solve the mystery! I like to let students work together to solve the mystery. The engagement and excitement around these types of challenges are SO fun!
