Students learn about equivalent names for different numbers, For example, equivalent names for seven include 4+3, 3+3+1, 5+2, 8-1, etc. Students work with different numbers to prove or disprove their equivalence and work with other numbers to create equivalent names. Core Actions 2 and 3 are observable in this lesson.
