An efficient and straightforward decimals learning exercise! Young learners round amounts of money and measurements to the nearest dollar or meter. Each section contains 20 problems, making it easy to divide up this asignment into...

Not only is Wassily Kandinsky fun to say, his art contains tons of angles. Learners discuss Kandinsky's music-inspired abstract art and four types of angles. They search one of his paintings for obtuse, right, straight, and acute angles,...

It's time to roll up those sleeves and get a little dirty in the second lesson plan of this series on the science of food. Investigate where plants and animals get the minerals they need to live in this two-part exploration of soil....

Young meteorologists examine the four main types of weather fronts and how they appear on a weather map. Participants learn about the difference between the types of weather fronts along with their distinguishing features. A...

A bouncing ball serves as more than entertainment when learning to apply quadratic functions to real-world events. This is the second of a two-part lesson, which can also be accessed from the website. The instructions say to measure the...

High schoolers explore displacement. In this displacement and density lesson plan, pupils find the volume of irregular shaped objects. Afterward, they determine the volume of containers. They compute the amount of water displacement.

Here is a simple, yet clever lesson on how to teach the important concepts of greater than, less than, and equal to. Pupils write their names down on grid paper - one letter per box. They compare their names and find a name that is...

How high can your pupils jump? Learners design an experiment to answer this question. After collecting the data, they create box plots and scatter plots to analyze the data. To finish the lesson, they use the data to draw conclusions.

Sew up pupil interest with an engaging, hands-on instructional activity. Learners first design a sports bag given constraints on the dimensions of fabric. They then evaluate provided sample responses to identify strengths and weaknesses...

Students explore parabolas.  In this algebra and technology lesson, students construct the equation of a specific parabola, then take digital photos of real-life representations of these parabolas.  Students create a podcast...

Use coordinate grid paper to plot points and identify shapes that are already plotted on the paper by saying their coordinates. Pupils also measure the distance between points and play the game Battleship. There are several web links and...

Here is an exciting exploration of a fascinating topic for your emerging ecologists: bird migration! They begin by visiting the US Fish & Wildlife Service website to discover which Arctic birds come to their areas. They are assigned...

Students construct a rocket from a balloon propelled along a guide string. They use this model to learn about Newton's three laws of motion, examining the effect of different forces on the motion of the rocket. They measure the distance...

Learners discover a method for determining the slope of a line by creating and comparing similar triangles. They fold coordinate grids to make three similar triangles then measure the sides to compare the relationships between the...

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...
