This powerpoint game reviews volume (length x width x height) using rectangular prisms. It uses the customary system of measurement (inches, feet, and yards). Students can touch the screen without it moving to the next question (good for those hands on counters). 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 is a type-in scoreboard. The scoreboard can be typed in during Slideshow Mode. Great for a guided math center or rainy day activity. Great for individual practice on the iPad!
