In this geometry activity, learners differentiate between similarity and proportion. They use scale factor as they solve for the different proportions. There are 15 questions.

What do you need to prove triangles are similar? Learners answer this question through a construction exploration. Once they establish the criteria, they use the congruence and proportionality properties of similar objects to find...

Fractions, ratios, and proportions: what do they have to do with segments? Scholars discover the midpoint formula through coordinate geometry. Next, they expand on the formula to apply it to dividing the segment into different...

Who knew running a greenhouse required so much math? Amaze future mathematicians and farmers with the amount of unit conversions, ratio and proportional reasoning, and geometric applications involved by having them complete the...

Asses the class to determine their knowledge of proportional relationships involving percents. Class members work through the nine-question assessment with a variety of percent problems. The multi-step problems involve simple interest,...

In this proportional rates learning exercise, students read story problems, determine the necessary information, and identify a sequence of numbers at a specified time. This three-page learning exercise contains three problems. The...

In this proportion worksheet, students compare two proportionate shapes and find the length of the "x" side. There are four pairs of shapes. Shapes include triangle, rectangle, parallelogram and a trapezoid.

What an impressive task it is to make dental impressions! Pupils learn how dentists use proportional reasoning, unit conversions, and systems of equations to estimate the materials needed to make stone models of dental impressions....

You don't want to be short bananas when making bread. Scholars use their math skills to make sure there are enough bananas to go around. Using measurements given in a recipe, they must determine how many bananas they need to increase the...

When will the gender wage gap disappear? Scholars use a provided infographic to see trends in wage gap over time. They use ratios of women's wages to men's wages to determine which decades had the greatest change in the wage gap. The...

Young learners explore nutrition and the food groups in these two mini-lesson plan ideas. First, kindergarteners have a discussion about their health and how different foods contribute to it before making their own personal food pyramid....

Students investigate proportion and ratio. In this geometry lesson, students set up the ratios of proportions correctly and solve for the unknown. They relate it to word problems.

Students apply estimation strategies and proportional reasoning to determine a scale comparing the planetary bodies to Earth. They convert measurements of time and distance using scientific notation. Both the metric and customary units...

In this proportion learning exercise, students find the missing side of 4 shapes that are similar to their mate. Shapes include triangles and quadrilaterals,. In the second part of the learning exercise, students use the scale...

In this algebra worksheet, students answer the question to what percent of a given number is a given number by setting up a percent proportion. There are 10 questions.

In this math activity, students are given a proportion statement. They use this ratio to solve related questions. Students compute the amount of food needed for one person and then for 500 people. Students convert between Euros, Pounds,...

In this similar triangles worksheet, students find the scale factor of 6 sets of similar triangles. Students find the scale factor of two similar triangles given a sketch with measurements. Students use proportions to find a missing side...
