This STEM CSI investigation is themed around a Valentines Day. It is the perfect activity for Valentines Day, but can be used all year round.
This activity will engage students by taking them on a journey to solve 10, 100 or 1000 addition and subtraction puzzles . Students narrow down the suspects by completing the activities and marking them off from the suspect list until one person is left. Who is the secret admirer?
Answer sheets are included
