This is how long we mow the lawn together. The assessment requires the class to work with combining ratios and proportional reasoning. Pupils determine the unit rate of mowers and calculate the time required to mow a lawn if they work...

How much land does a parcel hold? How much fertilizer does it take for a field of corn? Pupils answer these questions and more as they apply ratio reasoning and unit analysis. 

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

Sixth graders practice converting a fraction into a decimal and a percent. They explain relationships among rational numbers. They order and compare whole numbers, fractions (including mixed numbers), and decimals using a variety of...

Middle schoolers identify and interpret various ways of expressing probability as a decimal, fraction, percent, or ratio. They solve problems based on probability as they apply to real world applications.

Fifty-eight flashcards make up a set designed to reinforce math vocabulary. Within the set, you'll find bold-faced word cards as well as definition cards that offer a labeled example. Terms include base, percent, theoretical...

Using the concept of a candy vending machine, young mathematicians explore the sugar ratios found in different types of candy. Using the provided information, class members calculate and compare different ratios in...

Sixth graders practice the conversion of percents and fractions. They focus on the fact of both fractions and percents are part of a whole. In the independent practice the students also work with solving proportions.

Taxi! Have your travelers figure out how far they can go in a taxi for $10.00. They must account for the mileage rate and tip in their calculation. They can set up a table or make an equation to solve for the exact mileage they can...

Far out — plan a trip to space! Aspiring mathematicians steer a space vehicle through an asteroid field, calculate currency exchanges to buy provisions, and determine placement of charges to blow up asteroids. Along the way, they learn...

Make sure there is enough ice cream on hand. Learners try to find out how much ice cream to buy for a sports event. Scholars use a pie chart showing the percent of a sample of people who like different flavors of ice cream. Using the...

Students figure out the mileage from one state to another using a map. In this map lesson plan, students look at the scale factor and turn it into a fraction. They measure the distance between two cities and use the proportion to find...

Can you tell how tall someone is just by looking at their feet? In this activity, young mathematicians measure their height, arm span, and foot size, graph their findings, and answer questions about how these measurements are related....

Students investigate ratio and proportion as they solve problems. In this algebra lesson plan, students calculate the percent increase on salaries and convert between decimals and percents to calculate. They rate job positions from...

Students practice using ratios to solve real-world problems.

Students explore percent increases and decreases. They calculate the percent increase and decrease. Students use math to solve problems and communicate. They apply the given formula for percent increase/decrease.

Candy is a big business! Calculate the amount of money consumers spent on major holidays—Easter, Halloween, Christmas, Hanukkah, and Valentine's Day—based on the total amount of candy sales from 2011 and the percentage of each holiday's...

Finding out how to calculate tax and tip is a valuable skill that all young adults should be able to do without a calculator. Learners are given a bill and asked to calculate the tax, tip, and total amount. Calculations can be exact or...

Students determine the most equitable way to share space and cost between three schools for a fictional science fair. Given a diagram, a word problem, and a data set, students analyze and explain the best way for all schools to share...

Students create scale drawings, and ultimately scale models, of real-world objects in this Math lesson about ratios, proportion, scaling factors, and cross products. The lesson includes ideas for cross-curricular extensions and is...

Students examine how driving a hybrid car can save money and cut down on pollution.  In this hybrid vehicles lesson students complete an exercise that shows them how to work with proportions, percents, dimensional analysis and...

Young scholars use the terms: ratio, proportion, and measurement in their description of the life of a person one inch tall.

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