This product contains 40 task cards that can be used for math centers. Each task card has two numbers on it. Students will determine which number is bigger, first. Then, they will determine by how many more? I have noticed my first graders struggling with the question "how many more?", so I wanted to give them a center where they were practicing this skill with hands on materials. I have the kids use cubes when working at this center. There are center directions included in the download. Did I mention it has QR codes on each task card that takes kids to the right answer?! Enjoy! Please leave feedback if you like the product. If you have any questions/concerns, please contact me.
