You can either use this at a math center or use this to break down each place value family. Place value can be very difficult to teach children, but I have come up with an easier way. If you look at each group of three numbers as if they are a family, it makes it easier for students to grasp the place value. For example, the thousand family consists of hundred thousand, ten thousand, and thousand. The reason they are called the thousand family is because it is the last number in the family.
