This unit has a place value mat and number cards from 1 - 100,000. This is great to work on how many are in each of the place values and where the place values are. They can switch out the number cards if they need to or they can tell you how many are in a certain place value. A worksheet goes along with the place value mat and there is a pretest and post-test if needed that is included. To finish out the unit I have added 18 place value task cards that can be used as a center, independent or as a review.
