Unit 1, Lesson 6

Situations of unknown group size

Student Achievement Partners 30 min(s)

In this lesson, students apply their understanding of multiplication to situations of unknown group size. Students will work with concrete objects to analyze situations of unknown group size and represent the situations with multiplication equations with missing factors. Students will also solve problems to find the size of groups. Some problems involve missing factors that students may know from memory at this point (e.g., multiples of 10, 2, or 5.)
