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.

In Experiment 2, the executive resources were burdened with a secondary task. Both manipulations induced an increase in proportional answers and a decrease in correct answers to nonproportional problems. These results support the hypothesis that the choice for proportional methods is heuristic-based.

proportional reasoning to plan a school event or analyze aproblem in the community. By high school, a student might use geometry to solve a design problem or use a function to describe how one quantity of interest depends on another. Mathematically proficient students who can

Proportional reasoning helps us estimate v by an energy argument. The initial potential energy is PE ∼ kx2 0 or PE ∝ x2 0. The maximum kinetic energy, which we use as a proxy for the typical kinetic energy, is the initial potential energy, so KE typical ∝ x2 0 as well. The typical velocity is KE typical, so v typical ∝ x 0.

Learning Goals of Lesson 6 By the end of this lesson, I can: -solve rate problems using proportions -make buying decisions using unit rates
