Mentally Adding and Subtracting Ten

Students will learn strategies to identify ten more and ten less than a given two-digit number. The lesson begins concretely using base-ten blocks, then to the representational using a hundred chart. Ultimately, the lesson moves to the abstract level where students mentally identify ten more and ten less than a given two-digit number.
