Young scholars explore the concept of percentages. In this percentages lesson, students find the percentages of various colored m&m's in their bags. Young scholars find the cost of items before and after a discount. Students use...

In this percent application activity, students solve word problems containing concepts such as percent, proportions, sale price, discounts, interest, commission, tax, and more. Students complete 11 problems.

Learners compare two lengths using the area of a square. In this geometry lesson, students solve problems using ratio and proportion of the two shapes. They solve equations by taking the square root of both sides.

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...

Creating a solar system map is a snap thanks to a hands-on activity! Science scholars explore the solar system by building it wherever they choose during an interactive from PBS's Space series. Users pick both the location and scale for...

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....

Your class can become linear equations masters, as they calculate the rate of change of a function. They observe different types of coordinates as they relate to a graph, then use the Ti-navigator to move the line around and draw...

Students explore the distance formula using real world data from nonviolent marches for social change.  In this secondary mathematics lesson, students investigate the marches of Gandhi and King using maps overlaid with a coordinate...

Compare information from a US population cartogram and a standard US map. Learners draw conclusions about population density by analyzing census data a population distribution. They discover that census data is used to apportion seats in...

Math apprentices are introduced to the components of a linear relationship. In groups, they write story problems that incorporate this relationship and relates to the real world. They give their problem to the class for them to solve.

Analyze data on a graph to answer three questions after a robot race. Learners practice comparing ratios and reading points on a graph. Answers may vary on the last question based on accuracy of graphing. Use the lesson along with...

Feel like a detective yet? Pupils first watch a brief clip from the movie The Bone Collector. Using a photo of the suspect's footprint next to a dollar bill, they then use proportions to determine the size of the suspect's shoe.

Students solve problems dealing with ratios and proportions. In this algebra lesson, students rewrite word problems using equations and symbols. They correctly convert between percents and decimals.

Learners use cross-multiplication to find the unknown respiration rate of an astronaut. In this multiplication lesson plan, students also use the same process to find missing values in proportions.

Learners create different methods to analyze their data. In this algebra instructional activity, students differentiate between proportion and non-proportional graph. They use the TI-Navigator to create the graphs and move them around to...

Students meet NASA researchers who describe the relationship between force, energy and motion. They discuss how NASA's experimental X-plane is being tested to make space travel more reliable and show how proportionality and ratios are...

In this mean proportional worksheet, students work in pairs to solve right triangle problems. They use ratios and proportions of similar triangles to determine a missing length. This two-page worksheet contains 16 problems.

Fifth graders measure different heights and spans on a classmate's body such as full height, head width, leg length, and arm length. They place the data in a spreadsheet, determine the proportions, and draw a portrait using the proper...

Students identify how to create a flattering figure and demonstrate their knowledge through a portfolio page. They create a professional fashion presentation incorporating the principles and elements of design, explain each in writing,...

In this right triangles activity, 10th graders solve 10 different problems that include determining the means proportionally in each right triangle. First, they use the given information to determine the measure of each line segment....

Fourth graders conduct an experiment involving size and relative ability in smaller species using Madagascar cockroaches. They make predictions about how many pennies the roaches can pull, compare the results to human strength, and...

In this math worksheet, student compare the recipes for three different salads. Using the concepts of percents and proportions the amount of beans is calculated.
