This double-digit addition and subtraction game is an interactive and FUN mystery-type activity for students to solve double-digit addition and subtraction problems WITHOUT REGROUPING.

Available pre-loaded into Seesaw, Google Classroom, and in a hands-on printable version, students will have a blast as they solve this mystery.

The premise: In this mystery, a bunch of friends decide to have a summer picnic at the beach! While they are swimming in the water, a big wave comes and mixes up their picnic baskets. In order to find out which basket belongs to each friend, they will have to solve the clues hidden around the beach. Students will work together or independently to help them solve the clues and get their picnic baskets back to the right friends!
