Big Ideas: Any number or algebraic expression can represent a range of numbers, a single number, or a group of varying numbers. In mathematical relationships, the value of one quantity depends on the value of the other quantity. Using variables permits representing varying quantities. This lesson develops students’ understanding of independent and dependent values. This task uses a set of cards that can be paired up in more than one correct way to create values that have independent/dependent relationships. Students are asked to create pairs and articulate/justify the relationship between the values. Students will reason that the independent/dependent nature of a relationship can depend on the context of the values. The mathematical concepts in this lesson build toward students’ future work with expression, equations and proportional reasoning in grades 6-8. This lesson is the first of three that can be used together to deepen student understanding. Vocabulary: independent value dependent value Special Materials: Precut cards for task for each student or pair of students.
