A lesson plan for Grades K–2 Mathematics
In this lesson for grades 1 and 2, one of a four-part unit from Illuminations titled “Exploration of a Balance,” students participate in activities in which they focus on patterns and relations that can be developed from the exploration of balance, mass, length of the mass arm, and the position of the fulcrum. This resource is referenced in the Illuminations unit titled “Exploration of a Balance” and is related to the Illuminations lessons titled “Maintaining the Balance,” “Shifting the Balance,” and “Finding the Balance.”
