The Place Value Game comes with digit cards, instructions and 5 different levels of game cards (millions, hundred thousands, ten thousands, thousands and hundreds) The game can be played by as few as two students, or as many as you want. It even works well with an entire class. Not only will your students develop place value concepts, they will also learn probability. Each game card includes "Beyond the Game" extension questions so you can feel confident that they will be getting lots of practice. Works great as a "What to do when you're finished' activity or as a math center. My kids even played during inside recess they enjoyed it so much!
