Students determine the validity of Charles' Law. In this Charles' Law lesson plan, students measure the volumes of a gas at two different temperatures. They determine the volume at a high temperature and predict using Charles' Law what...

Eighth graders understand that proportional enlargement of shapes doesn't change the angles of those shapes. In this similarity lesson, 8th graders complete exercises to create enlargements of shapes and understand similar shapes.

Students gain appreciation for the drawings by Leonardo da Vinci. They show human emotion by drawing facial features in correct proportion - studying ratio of eye width to the rest of the facial features. They create values by varying...

Young scholars use hypsometers to measure tall objects.

High schoolers measure various dimensions of a male and a female dolls body and scale them proportionally to average human measurements. They calculate the appropriate scale factor (magnitude) to enlarge their doll and apply that scale...

Student identify the solution using geometric mean. In this geometry lesson, students create right triangles where the altitude of the triangle is the side containing the right angle. They modify shapes using Cabri software and observe...

The introduction to the lesson mentions a sailor's limited capacity to store drinking water on his ship. Pupils then set up an overnight experiment to remove freshwater from salt water by distillation. There is a math and map activity to...

Young scholarsare introduced to the Pythagorean Theorem by exploring right triangles and the squares built on each side. They apply the Pythagorean Theorem to real-world problems. Students u se informal and nonformal arguments of proof...

Students discover the relationships of the lengths of the sides of right triangles and right triangles using a series of drawings on dot paper. They investigate and solve problems of standard (customary and metric units) and non-standard...

Examine food choices and the nutritional properties of food groups with this visually appealing whole-class lesson plan. This will take a bit of preparation, but once you do it, you can use the materials for years. Using a food groups...

Using food as a manipulative is one of the best ways to incorporate hands-on learning in the classroom. This hands-on approach allows young mathematicians to compare, order, and identify fractions with the use of Twizzlers® and...

Students practice saying their numbers and identifying the words. They use whole numbers and decimals to practice grouping numbers into different categories. They write the word of the number they are shown.

Sixth graders examine how to select samples and apply them to an experiment. In this sampling lesson, 6th graders use a bag of yellow and blue cubes to take a sample. They predict how many of each color there are the bag. They set up and...

Designers measure their own rooms and produce a scale drawing. They use the Internet to visit sites to find the costs of purchasing new carpet, paint, or anything else they would like to add to their room. Using a $1500 budget, they will...

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...

Students test their knowledge of the Wright Brothers and their aircraft, and compute ratio of two numbers to determine the ratio between wing span and length of aircraft.

Students solve and verify the solution for unknown measures. In this geometry lesson plan, students identify the properties of circles. They use the arc, angle and segment relationship to find the missing measures.

Middle schoolers examine and compare traits of humans and crocodiles.  In this crocodile instructional activity students use a ratio to estimate the height of a person and compare that to a crocodile. 

Eighth graders discover the relationship between speed, distance, and time. They calculate speed and represent their data graphically. They, in groups, design a ramp for their matchbox car. The goal is to see who's ramp produces the...

Sixth graders apply the division and multiplication of decimals to convert dollars to various international currencies. In a travel simulation activity, they convert money, distance, and temperatures. During their "trip," students...

Sixth graders examine the causes of the stock market crash of 1929.  In this integrated math/history unit on the stock market, 6th graders study, research, and read stocks, visit a local bank, and create a PowerPoint to show the...

Sixth graders practice the conversion of percents and fractions. They focus on the fact of both fractions and percents are part of a whole. In the independent practice the students also work with solving proportions.

In this earth and beyond worksheet, students answer short answer questions about the atmosphere, the chemical compounds in Earth's atmosphere. Students visit different websites to conduct research of the discoveries of the scientist who...

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.
