Proportional Reasoning

In class, we discussed that the constant of proportionality shows the unit rate between units being compared to one another.
The constant of proportionality is determined by how to get from the first unit in a ratio to the second unit. For example, if there are 30 students in 2 classes, the unit rate would be 15 students per class. This means that the constant of proportionality is 15 since every additional class would get 15 more students. Tables are another way of viewing ratios. The worksheet here was done in class to show students how to find the constant of proportionality to determine missing values. 1/4 Classwork - Ratios in Tables WS 1/4 Classwork - Ratios in Graphs Video 1/4 Homework - Ratios in Graphs 1/5 Homework - Graphing Unit Rates Enlarge the slideshow below to review independent and dependent variables as well as how they can be used to interpret and solve a graph, table, or equation.
