This is a PowerPoint illustrating 1.NBT.4 Common Core First Grade Math - Adding 1 and 2 Digit Numbers by Lorena Russell. This engaging and interactive presentation helps kids visualize the results we want to see for each particular standard. This series was developed for use in my classroom to address the new Common Core Standards. The series is also available as a unit, with all 21 Common Core Standard lessons. This series is meant to serve as introductory lessons, not entire units. Sometimes uploading files causes odd changes. I stand behind my product. If there is a problem, please contact me and describe in detail. I will do my best to fix and will email you a new copy.
