Place Value Match Cards is great for a center activity. The students can work individually to match up the standard form, word form, and expanded form of numbers. They could also work in a small group and play a game of Memory Match. The set includes 24 numbers (standard form, word form, and expanded form) for place values of hundreds to millions. I've also included a blank sheet if you would like to make more for your classroom.
