"Make ten" strategy for addition (1st grade math)

A lesson about the concept in addition that I've termed "going over to the next ten". We have either two single-digit numbers or one two-digit and one single-digit number to add. Essentially, you first make ten, and then check what you have "left over".

This strategy promotes number sense (very important for elementary grades) and conceptual understanding.
