Here is my second forever freebie for 1st grade: What’s Missing? The PowerPoint game is a team effort. The class is divided into teams. Each team answer a question to get points. They are looking for one of the addends or the answer. If correct, the team gets the points. . The type-in scoreboard allows you to type in scores during Slideshow Mode. Great for a guided math center or rainy day activity. Great for individual practice on the iPad!
