Welcome to O'Connor's Innovative Ideas. This flipchart is a complete unit on number forms, comparison, and patterns. It is tied to the CCSS and was originally created for use in a second grade classroom to help teachers keep up with the demanding pace of the Baltimore City Units of Study Curriculum (this is unit 3). There are BrainPopjr links in this chart as well. There are notes for most of the pages with ideas on how to use the flipchart with your students. It is filled with ongoing practice problems, note pages, answer keys, interactive templates, and more.
