Watch as your classes buy into a rich lesson full of information. A video opener challenges individuals to determine the number of pennies that fit in a circle with a 22-inch diameter. Using lesson materials, scholars collect data and...

What would a meal be without the taters? The question is, how long does it take to peel those potatoes? Given the rate of peeling one potato, scholars predict the time it takes to peel the bag. The twist is that the first potato was...

Will the time come when women outperform men at the Olympic Games?Scholars investigate gender differences in Olympic Games performances. They study the historical participation of women and then analyze data to determine if women will...

You won't find yourself racing the clock on such a great task. Scholars use video information to predict the time left on a crosswalk signal after a pedestrian crosses. The video shows the time left on the counter, and individuals must...

Give plants the best place to grow. Given constraints on plant spacing, pupils design a raised bed garden using graph paper, then calculate the perimeter, surface area, and volume. They use the provided costs of lumber and soil to...

Make sure there is enough ice cream on hand. Learners try to find out how much ice cream to buy for a sports event. Scholars use a pie chart showing the percent of a sample of people who like different flavors of ice cream. Using the...

Determine the cheapest way to the airport. Pupils read a scenario about trying to get 75 people to the airport using two different sizes of taxis. Learners calculate the number of smaller taxis needed given a number of large taxis and...

Fifth graders discuss the relationship between equivalent fractions, ratios, and proportions. In this fraction lesson, 5th graders answer questions about a punch mixture in order to find the ratio of ingredients.

Fifth graders explore ratios. Using models and real-world scenarios, they complete tables and generate comparisons. Pupils demonstrate multiple ways of writing ratios and describe the differences between ratios.

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.

Ninth graders explore the concept of ratios. In this ratio lesson, 9th graders construct a to scale time line that starts at the beginning of time. Students determine the correct placement of big events in time such as when the dinosaurs...

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.

Tenth graders identidy and define various geometry terms, Students create exact replicas of a shape that is either smaller or larger than the original shape. Students prove that their entire shapes are larger or smaller in the same...

Middle schoolers explore the concept of the golden ratio. In this golden ratio lesson, students measure objects to determine if their measurements fit the golden ratio. Middle schoolers calculate the average measurements of the class.

Students practice using ratios to solve real-world problems.

Young scholars explore the concept of percentages. In this percentages lesson, students find the percentages of various colored m&m's in their bags. Young scholars find the cost of items before and after a discount. Students use...

Sixth graders practice using negative numbers by completing number equations.  In this math problem solving lesson, 6th graders discuss the different ways negative numbers can be used in a math problem and practice completing...

Students construct ratios using the hand as data. They use examples of cortical and trabecular bone found in the long bones to measure circumference, diameter, length, and weight of long bones. They perform computations using growth...

In this word based proportions worksheet, 6th graders solve and complete 10 different problems that include determining various word based proportions. They determine the number of miles a person can travel in particular number of hours....

The learner must use the given constant speed to find the unit rate. A table is made in order to relate the speed to the time and the distance. From the table, learners are able to see the unit rate in miles per minute and miles per...

In this similarity instructional activity, students use similar rectangles to find the length of a diagonal. They use symbols and write paragraphs to explain the problem. This one-page instructional activity contains one similar problem...

Students explore the exchange rates for five countries. They identify the units of currency of a number of countries. Students convert money amounts accurately from New Zealand dollars to another currency. They graph currency...

Students identify and use properties of similar figures. For this geometry lesson, students use proportions of the sides of triangles to solve triangular relationships. They use soda can as their visuals.

Seventh graders use educational software in order to practice lesson objectives. They define rate and ratio. Students solve distance problems given two variables. They also use a problem solving strategy that can be defended in its usage.
