MLC Board Meeting 45/17/03: - University of Oregon

• Count-on from larger: turn the problem round and count-on 3 after 4 as “5, 6, 7.” • Derived fact: “3+4 is one less than 8, so it is 7.” • Known fact: “3+4 is 7.” The last of the six bulleted approaches produces the answer most quickly. We merely have students memorize the appropriate number fact. ................
