Pairs simulate the energy usage of different countries by drawing beads from a bag, which contain different beginning ratios of non-renewable and renewable energy resources. The activity concludes with a series of questions to tie...

Want my name and number? It's 6.0221415 times 10 to the 23rd, and my name is Avogadro. Providing nine different activities, experiments, and labs, this lesson keeps Avogadro relevant to your class all year long. 

The test may say you have cancer, but sometimes the test is wrong. The provided task asks learners to analyze cancer statistics for a fictitious town. Given the rate of false positives, they interpret the meaning of this value in the...

At some point, everyone has been under pressure—even Dalton! Explore Dalton's law of partial pressures with young chemists as they measure the volume of air extracted from a sample compared to its original volume. Class...

Future environmental scientists compare data from two different conservation strategies. Alone this lesson is sufficient, but as part of the Exploring Biomes unit produced by the Arizona Fish and Game Department, it becomes top-notch. 

Use ratio and proportions to adjust recipe size. Middle schoolers investigate Australian food and adjust the recipe size for said foods according to the given situation. They then prepare Australian foods.

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...

Learners solve problems using equations and properties of integers. In this algebra lesson, students solve problems using ratio and proportion and graph their answers on a coordinate plane. They solve word problems using geometry.

Ninth graders gain an application level understanding of probability, symmetry, and ratios and rates that exists in one's everyday environment relative to human genetics.

Students investigate the currency exchange rate.  In this middle school mathematics lesson, student use proportions to exchange between the U.S. dollar and the euro.  Students come up with a product they would like to buy 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.

Students figure out the mileage from one state to another using a map. In this map lesson, students look at the scale factor and turn it into a fraction. They measure the distance between two cities and use the proportion to find the...

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.

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.

Learners are involved in a cooperative learning environment that analyzes fractions, ratios to time and distance, equivalent fractions and numerical relationships and expressions in quantitative problems. They take notes, relate...

This lesson focuses on unit conversion, proportions, ratios, exponents, and the metric system. Discuss measurement with your math class and demonstrate how to solve several health-science word problems. Give learners a chance to visit an...

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...

Your task today: count all the trees on a tree farm. To complete the assignment, learners first estimate the number of trees on a tree farm using random sampling. To improve their own response they then evaluate provided...

Combine creativity and coding in an activity where you are free to create your own animal. Try for something recognizable or not, the design is up to your unique students. The challenge is to use variables and variable expressions so...

In this similar triangles worksheet, 10th graders solve and complete 10 different problems related to determining the sides of similar triangles. First, they write three equal ratios to show the corresponding sides that are proportional....

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

Students explore numbers, computation, ratios, proportions, probabilities, statistics, and money in this six lessons unit. Practical applications in the real world are emphasized through an interactive approach to math in these lessons.

Young scholars 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.

Learners experiment with velocity, ratios, and rates. In this data management lesson, students throw a dart with and without using an atlatl and collect and record various data. Learners construct ratios based on the data and determine...
