Writing Equations from Tables with Independent and Dependent Variables and Quantities
Solve real-world and mathematical problems by writing and solving equations of the form x + p = q and px = q for cases in which p, q and x are all nonnegative rational numbers.
Use variables to represent two quantities in a real-world problem that change in relationship to one another; write an equation to express one quantity, thought of as the dependent variable, in terms of the other quantity, thought of as the independent variable. Analyze the relationship between the dependent and independent variables using graphs and tables, and relate these to the equation. For example, in a problem involving motion at constant speed, list and graph ordered pairs of distances and times, and write the equation d = 65t to represent the relationship between distance and time.
• identify independent and dependent quantities from tables and graphs.[6A]
• write an equation that represents the relationship between independent and dependent quantities from a table.[6B]
• represent a given situation using verbal descriptions, tables, graphs, and equations in the form y = kx or y = x + b.[6C]
I can statements:
I can identify independent and dependent variables and quantities by verbally stating and matching.
I can write equations by using information presented in tables and graphs.

• Problems around the room
• Grab and Take (Grab one problem and take back to area, solve, replace card, and repeat until all problems have been completed)
