Description

If your students are having difficulty grasping place value concepts, this is a math center you will come back to again and again!

My favorite thing about this center activity is that it can be easily differentiated and used at different points throughout the unit as students’ understanding of place value grows stronger. To start, I’ve included two-digit, three-digit, and four-digit card options. I usually start with two-digit numbers, and work my way up to three-digit options after a day or two of practice. For those students in need a challenge, I pull out the four-digit cards. Mixed sets are great for review.

Within each card set, there are also three options of card types to use. I’ve included numbers in standard form, word form, and base ten block models. You can use different representations for different groups of students or on different days. When students are familiar with all representations, use all the sets as a mixed practice option.

To prepare, print and laminate both pages of the work mat. Attach the top and bottom pieces with tape. You will need one work mat per student or student pair. Print out the card and number sets you wish to use. You may also wish to laminate these for durability. Provide a dry erase marker and your center is ready to use!
