# Interpretation of Algebraic Expressions

## Interpretation of Algebraic Expressions

1. Formulas and Stories - The students will be required to work with the relation between different mathematical expressions (formulas) and stories.
2. Functions from Tables - Students work with a function, beginning with a table and then a formula, to generate ordered pairs that follow the rule of the function.
3. Human Graph II - Students graph the functions k x 2 \$/h and k x 3 \$/h. The idea is to show that for each linear function the points fall onto a straight line.
4. Piggy Banks - The whole lesson revolves around a multipart story problem involving changes in two quantities over several days of a week. The initial quantities are equal yet unknown. Then transformations are applied to the quantities. Students are asked to compare the quantities throughout the week even though only their relative relationship can be determined.
5. Rules and Formulas - Students are given a rule and a data table supposedly generated according to the rule. Students evaluate whether: (1) the proper rule has been applied and (2) the result is correct.
