A complete instructional activity on dividing whole numbers by other whole numbers and getting a fraction result. Groups of learners use fractions bars, and strips of paper that are cut to specific lengths. The hands-on activities in the...

Geometry gets an engineering treatment in an exercise involving a belt wrapped around two wheels of different dimensions. Along with the wheels, this belt problem connects concepts of right triangles, tangent lines, arc length, and...

How many trees should we plant? Using an interactive as a manipulative, individuals find the mean, median, and mode for sets of data. They determine the number of trees to plant in each plot of land to reach a statistical goal.

Build upon and stack up data to get the complete picture. Using the applet, pupils build bar graphs. As the bar graph builds, the interactive graphically displays the mean, median, and mode. Learners finish by exploring the changes in...

Students become aware of the effects of tides on the Earth's rotation. In this tides lesson, students calculate the number of seconds lost over various periods of time.

Introduce the concept of exponential functions with an activity that extends the definition of exponents to include rational values. Start with a doubling function at integer values of time, then expand table to include frational time...

Here is a very interesting way of studying triangles and polygons. Pupils work together and use pieces of string to create a variety of shapes. Depending on how many kids are manipulating the string at any one time, the number of...

An AP calculus lesson begins with an activity to determine the volume of a solid using a cross-section. Next, learners review the ways to find the area between two curves , as well how to find the volume of a solid created...

Scholars can use area formulas, but can they apply what they know about area? The lesson challenges learners to think logically while practicing finding area of shapes such as rectangles, circles, parallelograms, triangles, and other...

Teach budding mathematicians how to square a triangle with an interactive that shows a graphical proof of the Pythagorean Theorem. Pupils alter the lengths of the legs using sliders. Using the inputted lengths, the applet displays the...

Boat ramps move with waves and changes in water level. Scholars decide on the proper length for a ramp so the angle connecting both sides is appropriate. They visualize the situation and use a simulation to view the results with their...

Who's on second? Young mathematicians use a diagram of a baseball field to find the distance a catcher must throw to reach second base. A brief video of such a play during a baseball game sets the stage for the assignment.

Paste this resource into your lesson plans like you'd paste a tile onto a mural. Given a diagram of a tile mural with rectilinear figures, future artists determine the perimeters and areas of the figures. They must then develop their own...

Storm into a better understanding of geometry. Using a tornado as a backdrop, scholars practice their skills finding perimeters and areas of rectangles. Learners apply their knowledge of the Pythagorean Theorem to find missing sides of...

Science can be quite tasty. A delectable unit from NASA shows learners why it's important to consider food, nutrition, and health in space. Four lessons explore the idea in great depth, including testing cookie recipes. Along the way,...

A comprehensive resource gets fourth grade physical scientists making observations about the period of a pendulum and then applying knowledge to a playground swing. Through seven different stations, they will record observations and...

Young scientists transform themselves into rivers, oceans, clouds, and drops of water in order to explore the water cycle. After assigning and explaining to students their different roles in the activity, the teacher reads aloud a...

With a partner, youngsters measure their pulse and breathing rates, both at rest and after running in place for a minute. While this activity is not novel, the lesson plan includes a large-scale classroom graphing activity and other...

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

Second graders determine the correct unit of measure to use for different situations. In this measuring lesson, 2nd graders are introduced to different unit of measure. Students study the origin of measurement and practice measuring....

Students identify units of measurement. In this measurement instructional activity, students predict the length and width of their hands and feet. Students discuss their findings and if their predictions were correct.

Students investigate shapes and sizes by creating a riddle.  In this geometry lesson, students read one of two books and investigate facts about an object's size.  Students write a riddle using the facts they have read and cut...

Students convert metric units of length, specifically meters, centimeters, and millimeters. In this lesson of converting measurements, students participate in various games which require them to put the measurements in order or convert...

Fifth graders examine patterns and relate to equations to solve math problems.  For this patterns lesson, 5th graders diagram, graph, use models and use tables to solve equations for real world problems.
