A Matter of Proportion

Height is dependent on weight—or is it the other way around? Given data from a physicians handbook, individuals compare the height and weight of males and females at different areas. They calculate differences and ratios to assist with...

Learners determine whether there is a constant multiple within the table through an instructional activity that presents a method for determining whether two quantities are proportional. Pupils analyze tables to determine if they...

Having problems with proportions? Then solve these proportion problems with an exercise that asks learners to first individually solve a set of problems involving ratios and proportional reasoning. Groups then discuss provided...

How can kids use math to learn about marine life? Combine math skills with science lessons in a resource featuring activities about life in the sea. Kids graph and calculate data, solve complex word problems, measure geometric shapes,...

Proportions are ratios found using multiplication or division. Middle schoolers solve measurement problems, find a figure's missing dimension, and find the distance between two points. Resource features four lesson plans with detailed...

Why does Nia's water taste saltier than Trey's if she put more into her cup than he did? Math masters set up proportions in order to compare the mixtures. This task effectively has learners apply the concepts of ratio and proportion to a...

Compare two different proportional relationships on a graph. It is up to your mathematicians to determine which of two moving objects have greater speed. A good example of a Common Core multiple choice question. 

Here you will find an excellent presentation for introducing or reviewing ratio and proportion. Pupils are introduced to some terms associated with ratios and proportions. Next, they are given examples to work with in order to gain solid...

How can you tell if number relationships are proportional? Mathematicians investigate proportional relationships. They compare and contrast functions and graphs to determine the characteristics of proportional relationships, as well as...

Take an indirect view of proportionality. Using a similar approach of direct variation, the resource shows how to solve inverse proportions. The video steps through finding the constant of proportionality to write the formula for the...
