Centers and independent work to practice Subtraction with
Regrouping
By: Jen Ross The Teacher’s Cauldron

I have made this pack In Black and White for ease of printing. I copied off each center onto different brightly colored card-stock. In this pack, there are four games, or centers, to reinforce subtraction with regrouping. Each center has a recording sheet for the group to do, which can also be used as “informal assessment.” I have also included posters for you to use to teach whole group or to put at the centers for the students to be able to refer to while working at that center. 1. “Read the Room.” Copy off the cards onto colored cardstock. The students walk around with their recording sheet and
clipboard (if they have them) and try to find all the cards. They write out the problem and answer them as they find them. 2. “Subtraction Sleuth” Students read each math problem and decide if they need to regroup or not and sort them into the correct column under the headers. There are two different activities that can be used for students to complete as independent work. 3. “True or False” The group of students will sort the subtraction sentences under the header cards. Then, they will correct the false problems on the recording sheet. For the independent work, the students will make a foldable book and sort the math problems. I gave an “illustration” of the foldable book. 4. “Flip It!” Use a deck of cards (A-9) or I have supplied a page of numbers that you can copy off a few times to use if you don’t have a deck of cards. Flip over two cards to make a two digit number, then flip over another set of two cards. Put the biggest two digit number on top to use for the math problem..

Put a piece of paper horizontal (long ways), and fold a piece of the bottom up, to make flaps. Then fold the paper in half down the middle to make it a folder. Glue the “label cards” on the front of the flaps. Staple the sides so the flaps stay closed.
