In this dimension activity, students determine the amount of material needed to construct three-dimensional figures. They find the dimensions of areas inscribed in given diagrams, determine the amount of profit, and the maximum flow of...

Students explore the surface area to volume ratio in cellular respiration. While participating in an interactive lab experiment, they examine proportional surface area and discuss nanotechnology. Students observe the effectiveness of...

Students examine the mathematical concept of proportions in an attempt to apply them in various types of problems. The real application of proportions is often found in word problems which requires a them to also practice a systematic...

Eighth graders solve problems using proportions with scaled drawings. They work with maps and blue-prints discussing scales and plans and examine different polygons and figure out the scale factors or proportions they have been changed by.

Middle schoolers discover scales for both the solar bodies' relative sizes and their distances from the sun. They find equatorial circumference and volumes of their solar bodies. Students apply estimation strategies and proportioanl...

Pupils explore proportions which are typical of the human body. Given a list of classic proportions from earlier centuries, students work in pairs to test the validity of the proportions. Pupils share their personal measurements. They...

Students work in cooperative groups to find the actual measurements of an historical building/landmark. Then they use ratio and proportion to figure the measurements that might be used to create a scale model of the structure.

Students collect real data through listening, counting and timing jazz pieces.They use ratios, rates, and proportions to report collected data and demonstrate an understanding of the concepts of rhythm and tempo in music.

Students apply ideas of proportionality from "Jack and the Beanstalk." They compare objects that are proportional to Jack with those that are in proportion to the Giant. They measure their hands and use those measurements to determine...

Students scrutinize the early twentieth-century artists who dealt with expressionism and abstraction, especially Marc Chagall. This four lesson unit examines the life and work of Chagall and supports the student creation of works similar...

Students investigate the use of multiplication and division of whole numbers to solve problems including equivalent ratios and rates.

Sixth graders explore a relevant application of ratios and proportions. They apply this concept through guided practice and interactive feedback.

In this Geometry instructional (work)sheet, students are instructed on how to find the geometric mean.  Students are then shown how the geometric mean is applied to proving similar triangles.

Seventh graders create a bathroom floor plan using measurement math. In this measurement lesson plan, 7th graders use measurement, proportionality, estimation, and area to design a floor plan. Students design floor tiles using centimeter...

Seventh graders explore the concept of percent problems. In this percent problem lesson, 7th graders use proportion equations to solve percent problems. Students find percentages of numbers and use proportions to determine percents in...

In this similar figures worksheet, students solve and complete 4 different problems. First, they write a proportion and substitute. Then, students find the cross products and simplify. Finally, they divide each side to find the value in...

In this proportions worksheet, students solve the world problems by writing and solving proportions for the given fractions in the six problems.

In this proportions and similar polygons activity, students solve the problems that use proportions, rations, fractions, and similar polygons.

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...

Ninth graders investigate the concepts of ratio and proportion.They solve examples with the teacher for ratios and proportions. A basic fraction review is used for a warm up in this lesson. The primary focus of the lesson appears to be...

Fourth graders use colored beads in two problems and explore the use of proportional reasoning as a problem solving method. Working Students, in groups, explain their reasoning strategies orally, and through drawings.

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.

The mathematics resource consists of an assessment with hints and solutions. Students answer questions that review ratios and proportions.

Learners assess their mathematics skills by answering these randomly generated multiple choice questions. Topics included are proportion applications and solving proportions.
