Adding Integers with Counters

Mrs. Bullington introduces a lesson on modeling integer addition using counters. The video covers adding positive integers, negative integers, and mixed integers using the concept of zero pairs. Students are encouraged to use counters or paper pieces to visualize the operations. The lesson includes practice problems to reinforce understanding of integer addition and the zero pair concept.
