Eighth graders measure height and shadow length of other students on a sunny day and develop a ratio. They apply the ratio to other students and objects using shadows to determine height.

Students research items that can damage hearing. They explore statistics about the decibels of certain objects. From the information collected, students create a bar graph. They formulate ratios to determine what sounds are harmful to...

Pupils explore the relationship between two variables. Students measure their arm span and height. They gather this class data to design a scatter plot. Pupils interpret the meaning of individual coordinates and the overall graph. ...

In this ratios activity, students solve 4 short answer problems. Students determine the number of girls/boys and oranges/water given a ratio.

Eighth graders explore ratios and proportions and how they are used in day to day life. As an activity, they find their own heart rate and then take a survey of other heart rates in the room. After organizing the data, 8th graders use...

Learners investigate the side splitter theorem. In this geometry lesson, students estimate and solve problems dealing with ratios and proportions. They identify angles created by lines that are parallel.

Students identify ratios to compare quantities and understand proportions. In this math lesson plan, students work in groups and use facts from the Holocaust to calculate ratios and percentages.

Middle schoolers examine various triangles and discuss how similar triangles have sides that are proportional. They utilize an ancient Egyptian method to determine the height of a flagpole.

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 experiment with proportions and drawing in this excellent Art lesson for grade 5-8. The lesson includes a PowerPoint slide show and requires the use of the educational software entitled "MatchWho". Students are required to use...

Students investigate the concept of using proportions to compare quantities while also practicing calculations for foreign exchange rates. They develop the skill of solving for unknown quantities of money while using an algebraic equation.

Students gain appreciation for the drawings by Leonardo da Vinci. They show human emotion by drawing facial features in correct proportion - studying ratio of eye width to the rest of the facial features. They create values by varying...

Seventh graders watch a video and enlarge and shrink scale by applying proportional thinking. They practice measuring, using percentages, computing area, and problem solving.

Ninth graders find the height of every day objects using techniques learned through postulates that allow triangles in a problem to be similar. They calculate the length of a missing side and solve proportions.

Learners are introduced to the concept of ratios. In groups, they convert sets of numbers into a ratio. After practicing, they use the ratios and proportions to solve story problems. They also calculate map distances and discover map...

Young scholars differentiate between similar and congruent triangles. In this geometry lesson plan, students identify the missing side and angle of a triangle. They identify the different ratio and proportion of the sides of a triangle.

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

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

Students give examples of each of Newton's three laws as they occur in everyday experiences. They visually represent and differentiate the difference between a direct proportion and an inverse proportion. Students explain how the...

Fifth graders explore the inverse proportional relationship and direct proportional relationship. They complete division chart showing the inverse relationship and direct relationship. Students are shown that division problems can be...

In this math activity, students will take home a letter to their parents explaining that they are studying Chapter 10: Ratio, Proportion and Percent. Then students will complete a homework activity in which they ask family and friends...

Young scholars build and apply concepts of geometry. In this geometry lesson, students create a building using proportions and scale drawings. They use Cabri technology to create a virtual drawing first.

Pupils incorporate their conceptual understanding of proportions to write a creative piece similar to the example poem.

Middle schoolers consider an individual habit and its cost. They study ratios and proportions, and use that knowledge to calculate the cost of a habit over extended periods of time. write a detailed comparison of the costs.
