Effects of Changing Dimensions Proportionally

In this proportions worksheet, learners solve and complete 7 various types of problems. First, they determine the better buy based on the information provided for each word problem. Then, students find the value of a variable given its...

In this geometry activity, students describe the effect of a proportional change on the perimeter or circumference and area of the given circles or quadrilaterals.  The one page activity contains ten problems.  Answers are...

Increase your sample and increase your accuracy! Scholars complete an activity that compares sample size to variability in results. Learners realize that the greater the sample size, the smaller the range in the distribution of sample...

Rates of change can be a slippery slope. The resource makes the connection between the rate of change and the slope of a line. It continues on to provide examples of how to interpret the slope and the y-intercepts of linear equations...

Parameters can move and change the steepness of a graph. Introduce the effects of changing the slope or the y-intercept of a linear graph. The resource shows how to incorporate changes on graphs and how they will move up, move down,...

I think we need a new teacher; this one keeps asking us for the answers! The video walks through how to solve for sample size when you are given a z score, proportion, and margin of error. It also explains a graph of the relationship...

Learners who view this video will gain a stronger understanding of percent of change. The tutorial provides a formula and a sample problem. As the tutor completes the example, she explains and clarifies each step that she takes to find...

How can an object as heavy as an airplane fly? Turns out the answer is quadratic! Your classes explore the Bernoulli Effect through an interactive graph representation. As a plane increases in speed, the lift force also increases. Young...

You don't want to flush your money down the drain! Have your classes complete a financial comparison between two different types of toilets. They use linear modeling to determine the most cost-effective model.

First identify the parts of the word problem. Next identify the variable, decide what formula to use, figure out the quantities, insert the quantities into the equation, and now solve. There are many parts to solving this word problem so...
