Unit 3

Multiplication and Division with Units of 0, 1, 6–9, and Multiples of 10

Math

Unit Length and Description:

25 days

Students learn the remaining multiplication and division facts as they continue to develop their understanding of multiplication and division strategies within 100 and use those strategies to solve one- and two-step word problems. The “2, 3, 4, 5 and 10 facts” unit (Unit 1) and the “0, 1, 6, 7, 8, 9 and multiples of 10 facts” unit (Unit 3) both provide important, sustained time for work in understanding the structure of rectangular arrays to prepare students for area in Unit 4.
