Exploring Scale And Ratio

A wonderful lesson incorporating math and physics skills along with specific details about the planetary bodies. The cross-curricular approach makes for a valid activity to challenge multiple ages and abilities. Your class could work in...

Scale drawings are an easy and plausible way to represent large things, such as roads and buildings, on paper. This tutorial explains what a scale drawing is and uses the example of a house to demonstrate how a scale drawing works. It...

Three angles of one triangle are equal to the corresponding angles in another triangle. Use a ratio of corresponding sides to find the scale factor. Actually, there are two scale factor values. The instructor will explain how to get both...

A model car, a life size car, now compare their sizes. Hmmm. Ok, set up a proportion and then figure out a ratio, and now you can express the relationship in terms of scale. Watch this video and the teacher will demonstrate just how to...

Scale drawings are used to represent many things. Scales are used all the time on maps, and in architectural drawings. Watch this video as the instructor illustrates a simple drawing of a blueprint to represent the footage of an actual...

Ratios are a comparison of numbers. So given a ratio, how can an equivalent ratio be written? Just multiply or divide, both the numerator and the denominator, by the same value. The result will be different numbers, but equal values that...

Fractions are ratios. What? Yes! A ratio is a comparison of numbers, and a fraction is a way to write a ratio. There are a couple of other ways to write a ratio. Do any come to mind? Can ratios be found in the real world? Yes!...
