ResourceSpotlight
Students investigate the total cost of a private party at each of three restaurants. Each restaurant states its pricing information differently, but all charge a flat room fee (represented by the y-intercept) plus a per guest plate fee (represented by the slope). Students model the cost of a party at each restaurant with the graph of a linear function.

Students are introduced to modeling linear data through an investigation of comparing grams of fat and calories in fast food hamburgers. Students will use multiple representations to explore aspects of the linear equation that models the data.

In this activity, students will make observation about the motion of two objects. They will compare and contrast this motion and consider how it corresponds to a graph representing the distance as a function of time. In the extension, students will explore the relationship between the slope and the rate.

In this activity, students will increase their understanding of the use of the formula T = r × p, which is encountered both in the real world and in the typical Algebra 1 class. They will calculate the amount of taxes and tips exactly, and then use estimation.

In this activity, students will use sliders to separate what effect each change in the Point-Slope equation has on the graph. Then they will calculate the slope and write their own Point-Slope form of an equation using two data points and use the Graph Trace to make predictions.

ResourceSpotlight
In this activity, students will work through a scenario of a business venture involving washing dogs. They will translate fixed and variable costs to a cost function and make a decision about how much to charge to wash per dog. When the break-even point is found, students must interpret it to answer the question.

In this activity, students will use ordered pairs, table of values, and a scatter plot to determine a function that represents real world data. Students will respond to questions about dog ages in human years, domain, range, and how the slope appears to be changing in the data/graph. In the extension students will use what they have learned in the activity to analyze cat’s ages.
