Building Algebraic Expressions

The big ideas for this lesson are that many real-world scenarios involve 2 things changing—called VARIABLES—and that independent variables cause the change for dependent variables. We can develop a way to discern which is which by using “Does ______ depend on _________, or does ___________ depend on ____________ (the other way around)?” statements. This will help students understand the relationship between the variables. Lesson objective: identify independent & dependent variables and use them to write algebraic expressions for real-world scenarios. Aligned to CCSS: 6.EE.9
