This resource can be used to help reinforce place value as well as basic operations. Give students a 2,3,or 4-digit number. Place these cards down in any order for a math center. Students will calculate the answer to each card. This is perfect for math center rotations. It will take students the perfect amount of time. If your centers are differentiated, you can challenge the students to calculate with a bigger number.
All you have to do is print and laminate for durability. BOOM, you have a math center that is stress free. :)
