Examine how nutrition plays an important role in our lives by conducting online research and developing lunch menus that satisfy nutritional requirements set up by the United States Department of Agriculture. Students download recipes,...

The speed of a dragonfly brings math into the real world as your learners collaboratively see the value in calculating unit rates in direct proportion problems. This six-phase lesson encourages you, as the teacher, to only ask questions...

Students investigate the concepts of differing gas prices and how they are set in different geographical areas. They conduct research about the economic concepts of supply and demand and predict the outcomes upon the prices of gasoline.

Students simulate going to a pizza restaurant, ordering a pizza, and determining whether a small, medium, large, or family size pizza is a "better-buy." Students calculate the price/per/topping and determine whether this price is "fair"

Use ratios to solve problems that are not proportions. The instructional activity has pupils solve multi-step ratio problems that involve fractional increases and decreases. The problems involve mark-ups, discounts, commissions, and...

Eighth graders use the unit price to compare which local grocery store has the best prices. Assign students to work with a partner and a role. One person is the recorder and the other is the mathematician.

Eighth graders follow a recipe, focusing on the concepts of ratio and proportion, to mix a batch of icing. They decorate cupcakes in the form of a pumpkin.

Eighth graders identify that a ratio is a comparison of two numbers and that a proportion is an equation that equates two ratios. They identify the extremes and means of proportions, as well as the product of the extremes equals the...

Students spend one month keeping track of the mileage and gasoline amounts they or their family has used. Information is entered into a spreadsheet to help calculate the average gas prices over time.

Middle schoolers work in groups to show understanding of the relationship between fractions, decimals, percentages, and the application of ratios and proportions. In this decimals, fractions, and percents lesson, students use real life...

Sixth graders explore economics by solving business math problems. In this ratio and proportion lesson, 6th graders examine different meals to be purchased at a coffee shop and compare which prices make which meals a better purchase....

Students identify he proportion of a cereal box. In this algebra lesson, students define the relationship between patterns, functions and relations. They model their understanding using the cereal box.

Students work independently to complete a problem solving activity that involves percent. This lesson is designed to be used as an assessment following a unit on percents. Students are presented with a problem involving a store that is...

Designers measure their own rooms and produce a scale drawing. They use the Internet to visit sites to find the costs of purchasing new carpet, paint, or anything else they would like to add to their room. Using a $1500 budget, they will...

Middle schoolers find the cost of an outfit. In this percentages activity, students look at ads, pick out an outfit, and find the sale price. They create a commercial and complete 4 included worksheets. 

Learners develop the key concepts of total, variable, fixed, average and marginal costs. The theory of using different business scenarios is applied to different situations for an extension to real life application.

This site contains a lesson about ratios and unit rates as well as guided and independent practice for students to review the skills.
