This beach themed PowerPoint game reviews the concepts of three digit addition and subtraction with/without regrouping. The game includes three rounds:
ROUND 1: The students will solve twenty three digit addition/subtraction problems with/without regrouping. They are encouraged to use their strategies as well as scrap paper or a dry erase board to show their work. All of these problems are multiple choice and the answers are given after each problem for instant feedback. The teacher can also have the students use error analysis and have the students figure out the reason why an incorrect answer was wrong.
ROUND 2: The students will solve five word problems.
ROUND 3 - THE LIGHTENING ROUND: Ten number sentences will flash on the screen one at a time. If the problem is correct, the students will stand up. If it is incorrect, they'll stay seated. This activity can also be done in any other format that the teacher wishes.
This activity can be used as an independent center, team game, or whole group with the students solving the problems on their own and then checking them together as a class.
**This game can also be used for regrouping practice over the summer!
