This is a PowerPoint game with an adorable winter theme. This game practices missing numbers in addition & subtraction. This is great for a whole class math activity, but could also be used in small group or as individual practice.
There are 20 questions. You just click on each question to go to it. The correct answer will appear once you click on the answer button. The question disappears on the question board after you've clicked on it so you know you've answered it. There is a type-in scoreboard that can be typed in during Slideshow Mode.
