 This is a ____________ drawing.

 At the park, there are 24 children playing and 20 of them are wearing blue jeans. The remaining children playing are not wearing blue jeans.  If I say “For every five children that are wearing blue jeans, there is one not wearing blue jeans.”  This statement shows an additive/multiplicative relationship.

 At the park, there are 24 children playing and 20 of them are wearing blue jeans. The remaining children playing are not wearing blue jeans.  If I say, “There are 16 more children wearing blue jeans than children not wearing blue jeans.”  This statement shows an additive/multiplicative relationship.

I am a good way to organize information and I show how two variable quantities are related. What am I?

 The ratio of green marbles in the bag to the total number of marbles in the bag.  This is what type of ratio?

A proportion is…

A ratio is…

A rate is…

 This is developed through activities involving comparing and determining the equivalence of ratios and solving proportions in a wide variety of problem-based contexts and situations without recourse to rules or formulas…

 Instead of first introducing algorithms, teachers should encourage these…

 A ratio of two measures in the same setting is a _____________ ratio.

 A ______________ ratio is a ratio of two corresponding measures in different situations.

 The ratio of the number of yellow marbles to the number of orange marbles in the bag.  What type of ratio is this?

 36:4  27:3  These are ______________ _________.
