Amaze your classes with the ability to find side lengths of triangles immediately — they'll all want to know your trick! Learners use the Pythagorean Theorem and special right triangle relationships to find missing side lengths.

Pupils figure out how to be resourceful when tasked with finding the area of a triangle knowing nothing but its endpoints. Beginning by exploring and decomposing a triangle, learners find the perimeter and area of a triangle. They...

Forget your ID number? Your pupils learn to use logarithms to determine the number of digits or characters necessary to create individual ID numbers for all members of a group. 

Triangle centers and the segments that create them easily become an exercise in memorization, without the help of engaging applications like this lesson. Here the class investigates the measure of center that is equidistant to the three...

Can you graph your story? Keep your classes interested by challenging them to graph a scenario and interpret the meaning of an intersection. Be sure they paty attention to the detail of a graph, including intercepts, slope,...

Everybody loves video day! Grab your class's attention with this well-designed and engaging resource about graphing. The video introduces a scenario that will be graphed with a piecewise function, then makes a connection to domain...

Computers are useful for more than just surfing the Internet. Pupils first investigate scatter plots and estimate correlation coefficients. Next, they use Microsoft Excel to create scatter plots and determine correlation...

Learn about polymers while playing with shrinky dinks. Young scholars create a shrinky dink design, bake it, and then record the area, volume, and thickness over time. They model the data using a graph and highlight the key features of...

Research various types of bridge designs. Your class will be asked to consider what it would be like without bridges while learning about how they work. They will construct a model bridge based on given parameters. They then calculate...

Jump at the chance to use this resource. A kinesthetic activity has classmates jumping in several different ways (standing, single-step, and multiple-step jumps) to create handprints on poster paper taped to the wall. They measure the...

Ninth graders study the sun and its distance from Earth.  In this Sun's diameter lesson students examine how measurement data permits accurate measurement of the sun's diameter. 

Students brainstorm healthy food choices. In this health science lesson, students calculate how much of each food group they need daily. They plan a menu based on the "MyPyramid for Kids" food guide.

Students examine inflation over the years and learn to calculate how it changes over time. For this money management lesson, students learn how price changes affect their purchasing power, how to come up with strategies for dealing with...

Third graders engage in a lesson that is concerned with the estimate and approximation of different masses. They weigh different objects and compare the different measurements and then use a balance to compare them. Students define the...

Third graders investigate liquid measurements by estimating how many cups it takes to fill containers. The students predict the liquid measurements and then find the actual amount using the water in a bucket. Students then compare...

Students explore measurements by completing worksheets in class. In this geometry lesson, students identify the basic measurement units in both the English and metric systems. Students analyze 2 and 3 dimensional objects and identify...

Students engage in a lesson to measure body parts. They use the measuring tape to record the data of body measurements. Students must choose the appropriate unit of measurement and compare the data for the different parts of the human body.

Second graders observe and demonstrate how to measure different objects. They listen to the book "Corduroy," and measure different aspects of a teddy bear, discuss how to measure using a variety of units of measurement, and complete a...

Students explore nutrition by completing math problems in class. In this food conversions lesson, students identify what the kumara plant is and how it can contribute to human health by regularly consuming an appropriate amount. Students...

Students determine just how large the sun is. In this solar system lesson, students follow the prescribed steps to draw a box that represents the size of the sun and its mass compared to the entire solar system.

Fourth graders practice multiplication and division with cooking recipes. In this math lesson, 4th graders look at a recipe and change it so that it works for twice as many people or half as many people. 

Students use chips to represent units to show examples and non examples of fractions. In this fraction lesson plan, students show what chips can be used for different fraction scenarios.

Learners participate in a Mini-Olympics with measurements. In this measurement activity, students throw items and predict how far they will go. They measure the actual distance and find the difference between that and their estimate. 

Sixth graders study measurement problems. In this geometry lesson, 6th graders discuss the different types of measurement used in sports and answer questions regarding measurement problems in sports.
