From Patterns of Input and Output to Algebraic Equations  

From Patterns of Input and Output to Algebraic Equations
Students explore the relationship between input and output values and learn to use algebraic expressions and equations.

4-8 Lesson Plan
Linking Number Patterns and Algebraic Expressions  

Linking Number Patterns and Algebraic Expressions
Students practice using algebraic expressions by recording data from a video segment in which two staircases ascend at different rates. They record the patterns in two-column tables, draw line graphs and write simple algebraic relations.
