Unit 3 is typically a six-week unit taught in December and January.
Mathematics is the study of patterns and relationships. In this unit, students analyze and apply numeric patterns as they explore the interrelated concepts of multiplication and division.
Students begin the unit by investigating various models and structures for multiplication and division. In Grade 2, students were introduced to multiplication as repeated addition and division as sharing equally. In Grade 3, students work with arrays and comparison problem structures. Building on their understanding of concrete models, Grade 3 students develop efficient ways to represent multiplication and division using models. Instructional tasks assist students in making the connection that multiplication and division are inverse operations. Problem solving is an integral part of the unit as students explore examples of multiplication and division in real world contexts.
In the second part of the unit, students develop strategies for learning basic multiplication and division facts. By the end of the unit, Grade 3 students are expected to demonstrate mastery of multiplication facts for 0, 1, 2, 5, and 10, as well as to apply a variety of strategies for other basic facts. Students who have developed efficient strategies for quick mental recall of basic facts will be able to use this knowledge for estimation and computation with larger numbers.
In the third part of the unit, students apply knowledge of multiplication and division to solve equations using Hands on Equations materials. Instructional tasks in Unit 3 continue to build the foundation for quantity relationships that will be assessed later in Unit 5.
