7.RP.1

7.RP.1 – Compute unit rates associated with ratios of fractions, including ratios of lengths, areas and other quantities measured in like or different units. For example, if a person walks 1/2 mile in each 1/4 hour, compute the unit rate as the complex fraction 1/2/1/4 miles per hour, equivalently 2 miles per hour.

Math Nspired: Equations from Unit Rates
This lesson involves finding a linear equation and confirming the equation represents a proportional relationship with numeric values in ordered pairs or in functions tables. Product: TI-Nspire(TM), TI-Nspire(TM) CAS
Math Nspired: Proportionality in Tables, Graphs and Equations
Students will recognize and identify the characteristics of proportional and non-proportional relationships by analyzing a table, equation, and graph. Product: TI-Nspire(TM), TI-Nspire(TM) CAS
Math Nspired: Proportions in Stories
This lesson involves inputting data into a table, observing the data on coordinate plane, and inputting an equation that corresponds with the table of values. Product: TI-Nspire(TM), TI-Nspire(TM) CAS
Math Nspired: Recipe: Rate of Change
Students look at unit rate in a real-world context. They will use ratios to create points, plot them, and determine the mathematical relationship for the plotted points. Then, they will predict other points based on the relationship determined. Product: TI-Nspire(TM), TI-Nspire(TM) CAS
Math Nspired: Spring Scale Strength
In this lesson, teachers will use a spring to help students learn that the constant of proportionality between two proportional quantities is the unit rate of change. Product: TI-Nspire(TM), TI-Nspire(TM) CAS
