Students must convert different measurements including length, weight, capacity, and time. Students compete against one another groups.. There are 20 questions and 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 are 2 scoreboards: a touch scoreboard and type in scoreboard. The type-in scoreboard allows you to type in scores during Slideshow Mode. Great for a guided math center or rainy day activity.
