Topic D introduces units of 9 over three days, exploring a variety of arithmetic patterns that become engaging strategies for quickly learning facts with automaticity (3.OA.3, 3.OA.7, 3.OA.9). Nines are placed late in the module so that students have enough experience with multiplication and division to recognize, analyze, and apply the rich patterns found in the manipulation of these facts. As with other topics, the sequence ends with interpreting the unknown factor to solve multiplication and division problems (3.OA.3, 3.OA.4, 3.OA.5, 3.OA.7).
