In this ratios worksheet, students solve 20 problems that pertain to equivalent ratios and writing ratios in the simplest form.

Students study the Golden Ratio and its relationship to Renaissance artists. After exploring proportions and ratios used by Renaissance artists, students create a mix of ten variations of color paint, and record the ratios of primary...

Students examine proportionality in Wind in the Willows by comparing Mr. Toad, objects proportional to him and objects proportional to humans. They then measure a stuffed Mr. Toad and make common objects proportional to Mr. Toad???s...

Students create their own pizza, "order" it from the Internet, and see digitized versions. They calculate the area of various size pizzas in order to do cost analysis to determine best buys.

In this ratios worksheet, students find the missing number in the second ratio in the problem. Students complete 9 ratio/proportion problems.

Sixth graders investigate estimating. In this estimating lesson, 6th graders estimate how much rice is eaten around the world. Students estimate the percentages of rice eaten by other countries. Students compare rice production to...

Fifth graders find the percentages of rough rice that can be eaten. In this percentage lesson, 5th graders look at 100 lbs. of rough rice and see the steps needed before it can become the white rice sold in stores. They find the...

Seventh graders explore the concept of proportions. In this proportion lesson plan, 7th graders play a review game involving whiteboards. Students work in groups to solve a given proportion the fastest. Students also work in pairs to...

In this percent/proportions worksheet, students solve a set of 6 short word problems; all problems involve percent and/or proportions.

In this geometric proof learning exercise, learners use geometric theorems and rules to prove given statements. They prove that given lines and angles are similar. This five-page learning exercise contains ten problems.

In this proportions worksheet, 8th graders solve and complete 10 different problems that include difficult word based proportions. First, they solve each proportion as described. Then, students write their answer on the line provided for...

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.

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

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.
