Learners solve problems with ratios and proportions. In this algebra instructional activity,students apply the concept of ratios and proportions to the real world.

Reduce variability for more accurate statistics. Through simulation, learners examine sample data and calculate a sample mean. They understand that increasing the number of samples creates results that are more representative of the...

Learners solve problems with slopes. For this algebra lesson, students identify the slope of a line and relate it to the rate of change.  They graph their lines on the TI and observe changes in the lines.

Students calculate ratio and proportion. In this unit rates lesson, students estimate using proportions and find their errors in doing so. They calculate unit rates and define the concept of unit rates.

Ninth graders apply proportional reasoning to a real-life situation.  In this Algebra I lesson, 9th graders explore a series of equations that relate to a display sign that compares the owner’s bagels to competitors bagels. ...

Young scholars calculate distance and proportion of objects. In this algebra instructional activity, students define proportion and how it is used in math. They solve the problem through guided instruction.

Pupils solve algebraic proportions. In this algebra instructional activity, students convert between fractions, percents and decimals. They solve problems using the distributive property.

Students solve problems using ratios and proportions. In this algebra lesson, students verify proportions, solve for the unknown and use real life scenario to model proportion.

Don't leave your classes vulnerable in their calculations! Help them understand the importance of calculating a margin of error to represent the variability in their sample mean. 

Learn to use mathematics to your advantage! Using linear modeling, scholars predict the date and time the Apple App Store reaches 25 billion downloads. Considering the prize for the 25 billionth download was a $10,000 gift card, modeling...

Pupils take photos from a given distance and determine the height of the person using a scale factor. Pupils calculate the ratio of student actual height to student photo height. They take pictures from 3 different distances to see if...

Elementary or middle schoolers use ratios to discover some nearly constant relationships between measurements of parts of the human body. They find and record pairs of measurements and determine the relationship between the pairs. Pupils...

Students investigate the currency exchange rate.  In this middle school mathematics lesson, student use proportions to exchange between the U.S. dollar and the euro.  Students come up with a product they would like to buy and...

Students 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, students calculate the percent increase on salaries and convert between decimals and percents to calculate. They rate job positions from 1936...

Students measure the activity and parts of a robot. In this algebra lesson, students explore ratio and proportion using their classroom. They apply properties of fractions as they cross multiply to solve problems.

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