This reindeer themed PowerPoint game reviews the concepts of two digit addition and subtraction with/without regrouping. The game includes three rounds:
ROUND 1: The students will solve twenty two-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 reindeer themed word problems.
ROUND 3 - THE LIGHTENING ROUND: Sixteen number sentences will appear on the screen. If the students think that the problem is correct, they will stand up. If they think it's wrong, they will sit down or stay seated. See if your students notice the secret pattern. :)
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.
