Proportions and Expressions
|
This chapter continues to build the big idea of proportional relationships in the context of real-world situations. The themes are proportions and expressions. During this chapter students:
- Look at similar figures in order to determine how the figures change and make scale drawings.
- Examine tables, graphs, and situations and use informal strategies to solve proportional situations.
- Use manipulatives (called “algebra tiles”) and write expressions to represent the perimeter and area of these shapes, building skills like combining like terms and equivalent expressions.
