Exercise Set 3.3: Variation

Create a variable list of problems. Groups come up with four scenarios. Each situation represents different types of variation, direct, inverse, joint, and combined. Teams then generate questions about their contextual problems for...

Scholars determine how two quantities vary with respect to each other. They complete a fill-in-the-blank activity by stating whether the entities vary directly, inversely, or jointly, create equations that match different variations, and...

Once learners realize what direct variation is, they see it's just a type of linear function. The lesson plan poses a general question that leads to the creation of the y = kx formula. The resource includes discussion prompts and ideas...

Direct variation? Constant of variation? Constant of proportionality? Two variables related? If one variable changes what happens to the other variable? What do all these terms have to do with each other? Watch this video as the...

y=kx. This is the direct variation equation. You have been given a table of values. So look at the table and figure out how to use this equation to write an equation that represents what is happening in the table. Does the equation...

This problem may sound a bit confusing, but the teacher does a great job explaining what direct variation is. So watch this video and learn about k. It is a pretty direct explanation.

Enhance pupil understanding of proportions and variable relationships by studying direct and inverse variation. Use the idea of a proportional relationship to teach direct variation. Then use a similar pattern to help individuals...

What is a constant variation? How can something change and be constant? Oh, the rate of change is constant. So if there are two variables that are directly proportional they can have a constant of variation? Yes! Still a bit confused?...

Use the formula for direct variation to solve for y, after finding the value of k. When you use the formula and determine the value of k and x, you can plug in those values to determine the value of y. A quick tutorial that takes you...

Direct variation? Inverse variation? Constant of variation? Constant of proportionality? Two variables related? What do all these terms have to do with each other? Watch this video as the instructor illustrates and explains what all...
