Goals of the Unit
Through their work in this and other algebra units, students learn important questions to ask themselves about situations that can be modeled mathematically.
(1) identify quantitative variables in situations
(2) recognize situations where changes in variables are related in useful patterns
(3) describe patterns of change shown in words, tables and graphs of data
(4) construct tables and graphs to display relations among variables
(5) observe relationships between two quantitative variables as shown in a table, graph, or equation and describe how the relationship can be seen in each of the other forms of representation
(6) use algebraic symbols to write rules and equations relating variables
(7) use tables, graphs, and equations to solve problems
(8) use graphing calculators to construct tables and graphs of relations between variables and to answer questions about these relations
