This is a PowerPoint game that can be used year round, but has a cute heart theme that's perfect for Valentine's Day too. This game practices subtraction with regrouping. 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 question disappears 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.
