I have combined the Math In Focus, Grade 3: Chapter 3: Addition up to 10,000 activities and posters as a bundle! Each file is listed by lesson when you unzip the file upon purchase so you find them easily and print them as needed. Many of the activities can be used in a dry-erase clear pocket to be reused each year. You can edit/alter as needed.
Each lesson contains vocabulary posters, study guide, I can statement posters, guided activities, independent activities, and games.
Thank you and I hope you find this useful!
