Don't lose your marbles. Scholars use an interactive to create a triangle that closes off a portion of a sidewalk with loose marbles. The Law of Sines helps them find the side measures of such a triangle.

Kindergarteners explore various representations and uses of numbers to develop number sense. They participate in an activity and arrange patterns into groups. Students compare the sets and describe the objects in each set.

Your class has gathered their data, so what's the next step? They need to display and analyze their data, and a bar chart is a perfect tool for the job. This resource provides the step-by-step instructions those kids need to construct a...

Young scholars use a variety of technology-assisted weather observation tools to observe and record local weather. They identify, measure and record weather conditions, summarize types of clouds and make graphs of their observations....

How are arc lengths and radians related? An interactive resource demonstrates the relationship as pupils create arc lengths in a unit circle and compare them to the angle measurements. Questions ask individuals to build upon this...

Why is calcium good for the body? Where is it stored? Young chefs discover the importance of calcium and review a list of foods that are rich in the material. They then make delicious smoothies high in calcium! Teaching kids how to...

Students participate in an experiment about evaporation. In this water cycle lesson, students use water, thermometers, and measuring tools to make a puddle and measure the size four times throughout the day. Students discuss their data...

Venn diagrams are helpful in understanding the idea of a set and using attributes to sort items. This basic plan is an introduction with an added bonus of an applet that can be used to demonstrate the activity. If a classroom of...

Learners explore the concept of univariate and bivariate data. In this univaritate and bivariate data lesson, pupils discuss the differences between univariate and bivariate data. They work sample problems where they must construct box...

Split it down the middle. Using the tools of geometric construction, the video shows two different methods of constructing a 30-degree angle. The first method bisects an angle of an equilateral triangle. The second uses the diagonal of a...

Rescue animals in the zoo by applying math concepts. Groups of learners solve three missions involving oxygen, food, and climate control. Each group selects an animal from one of four bio-domes.

Where did the pH scale come from? Take a deeper look at a most important measure of ion concentration using a simulated physical determination. Young chemists prepare a series of dilutions after determining a dilution factor for the...

Three main factors determine the wave height experienced in the ocean. Scholars use a virtual simulator to alter wind speed, fetch, and duration. Each combination creates a unique wave measured in significant height.

Students work in cooperative groups to create a working weather station. Tkey use the weather station to collect weather data over a one-week period. Students compare the data from their weather station to actual weather information...

Students examine the differences between air temperature and ground temperature.  In this investigative lesson plan students find NASA data on the Internet and use it to create a graph. 

Learners build confidence working with geometric tools and develop their construction techniques in the sixth lesson plan of the 29-part series. Given a geometric description, they use a compass, protractor, or ruler to create it....

Talk about a cool tool! Convert between units with the click of a mouse using a handy online resource. Enter the starting measurement and units for quantities such as torque, speed, and inertia, then sit back and relax while the computer...

Different colors of the spectrum travel at different speeds through media, causing them to refract at different angles—which allows humans to see their colors. Through a simulation, pupils see how air, water, and other media bend light....

People can make a difference in the world without leaving their homes. Using an eye-opening resource, scholars complete a handout as they consider the strengths and weaknesses of the Internet as a tool for social activism. Finally,...

In this counting to ten worksheet, students solve four problems in which objects in a set are counted. Kids then draw more objects to make ten in all. Students then write the number 10.

In this fraction worksheet, learners use twizzlers to demonstrate various equivalent fractions. Students complete ten greater than, equal to, and less than questions.
