The original drawing is eight units — how big is the scale drawing? Classmates determine the scale percent between a scale drawing and an object to calculate the length of a portion of the object. They use the percent equation to find...

Display data over a larger interval. The fourth segment in a 22-part unit introduces histograms and plotting data within intervals to the class. Pupils create frequency tables with predefined intervals to build histograms. They describe...

Lead your class on an exciting journey through the world of math as they review geometry facts and solve for unknown angles. They learn how to use auxiliary lines and congruent angles to correctly complete each practice problem...

Determine whether two triangles are similar. The lesson presents opportunities for pupils to find the criterion needed to show that two triangles are similar. Scholars use the definition of similarity to find any missing side...

Data encryption is an important security measure for sensitive data stored on computers. Pupils learn how to utilize matrices for creating code. They also get a great review of matrix multiplication, inverse matrices, and the identity...

Lead your class on a search for precious bones. Using a presentation, the class investigates the golden ratio in art and nature. Groups of pupils measure specific bones and find the average ratio for the class. To further cement the...

Keep your mind and body fit with a fun activity about the five food groups. After going over the functions of fruit, vegetables, grains, meats and beans, and dairy, as well as oils and fats, learners participate in a bean bag toss...

Ever wonder why Pluto isn't considered a planet? Or how large the Earth is compared to the other inner planets? Explore the universe with a series of projects that simulate different aspects of our solar system. The activities require...

Wrap up an engineering lesson plan with a worthwhile project. An engineering design task challenges groups to develop a package for a pharmaceutical company given constraints on the volume. Learners then create a presentation to...

Both The Ugly Duckling and The Tortoise and the Hare are great additions to an elementary language arts lesson. Young readers focus on the literary elements of each story, including characters and plot development, and apply...

Junior geometers use hands-on manipulatives to explore and describe the properties and attributes of a fundamental polygon, the triangle. They learn different kinds of angles and their measurements. This well-written lesson plan provides...

Using spectroscopes, high school astronomy, physics, or chemistry learners observe emission spectra from several different sources. This stellar NASA-produced lesson plan provides terrific teacher's notes and a student handout. Make sure...

Middle and high schoolers use a spreadsheet to graph data. In this graphing lesson, learners determine how two parameters are correlated. They create a scatter plot graph using a computer spreadsheet.

Sixth graders engage in problem solving, communicating, reasoning, and connecting to represent and solve problems, using geometric models.

Students discover the metric system through video clips and Internet activities. In this measurements lesson, students practice using the units of measure for the metric system and compare them to the less popular English system....

Students brainstorm how math is used in daily life. They develop a class list of different topic areas in which math is used and work in small groups to think of specific examples of how math is an important part of their lives.

Sixth graders work in teams to design the perfect bedroom. The teams must create a room that is functional, original, and stays within a budget of $650.

 In this geometry instructional activity, learners read The Greedy Triangle and use geoboards to construct geometric shapes. They identify the number of sides and angles each shape has.

Review and use standard units of measure with your math class. They move from station to station estimating and measuring length, volume, weight, and area. At each station they estimate and measure, and then compute the difference...

Fourth and fifth graders make a protractor and identify various angle types. In this protractor and angle lesson, learners make their own protractor and use it to measure a variety of angles. They complete worksheets while identifying...

Here is an excellent lesson for young learners who are just beginning to explore the concept of using units to measure length. They rotate through four classroom centers in order to gain practice in utilizing this important skill.

Upper graders identify the surface area and attributes of figures that are measurable. They estimate, measure, and record perimeter, area, temperature change, and elapsed time, using a variety of strategies. They also determine the...

Learners divide a poster board so everyone gets the same amount of area to decorate. Youngsters talk about the different ways to divide a rectangle. They measure their lines to make sure that each piece is equal and then decorate their...
