This is an activity that you can use for students to fill in the missing number on each strip. I have them printed on card stock and laminated. Students use expo markers to fill in the answers and once they are finished their answers get checked by myself or my assistant.
It is a great activity to use for a math center. There are blank templates that you can fill in if you need more challenging numbers for your students!
If you have any questions please feel free to ask. Please leave some feedback! I am new at this and would love to hear some opinions. Thanks!
