This clip is from a professional development video of fourth graders engaged in exploring the relationship between when numbers are added to themselves and when numbers are multiplied by each other. This segment shows the children engaged in Common Core Practice Standard #7—Look for and make use of structures. The learners are looking for patterns using concrete (square tiles) and/or pictorial models (array structures on grid paper) Additional resources include a video transcript, teaching tips, and a link to a professional development reflection activity based upon the video. A related clip (cataloged separately) shows the same exploration by the same students but Common Core Practice Standard # 8- Look for and express regularity in repeated reasoning is evident.
