Learning about tangents doesn't have to be a slippery slope. Pupils drag a point around a unit circle to see how angle affects the slope of a line. They individually answer a set of challenge questions to come to the conclusion that...

Students identify the different types of bridges. Using the internet, they research information on how they are built by completing a scavenger hunt. Locating a specific area, they determine which type of bridge would be appropriate and...

Students explore the concept of modular arithmetic and cryptography. For this modular arithmetic and cryptography lesson, students use applets to explore modular arithmetic using a clock and Caesar Ciphers. Students exchange their...

Students explore the concept of the corner problem. In this corner problem lesson, students use the TI-NSpire to determine the maximum length a rod can be and still pass horizontally around a corner. Students use similar triangles to...

Learners explore the concept of fractals. In this fractals lesson, students play the "Chaos Game" via an applet. Learners place dots on the screen to recognize that they have created Sierpinski's Triangle.

In this math literacy worksheet, 4th graders solve the five problems to review basic skills for the fourth grade focusing on the concepts of basic geometry and number sense.

Ninth graders participate in a lesson focused on the concept of basic statistics. They find the mean, median, and mode of different data sets. More advanced students could practice creating a bell curve from the data.

Ninth graders access a star worksheet and determine properties of polygons.  In this investigative lesson plan students complete a worksheet and discuss myths. 

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...

Ten questions make up an interactive all about integers. Scholars answer multiple choice, short answer, and discussion questions using a 4x4 chessboard and dominoes.

Watch the exponent expression do the negative exponent dance! An interactive lesson uses an animation to show how negative exponents become positive. Learners manipulate the expression and then respond to conceptual questions.

Classify this resource into the "Use" pile. Scholars use an interactive coordinate plane to plot polygons given coordinates for the vertices. They use properties to classify each polygon and answer a few challenge questions regarding the...

What's the rule that makes it true?  A virtual function machine generates output values as learners submit the input values. Their job is to analyze the inputs and outputs for a pattern and write a function rule.

Watch as a function machine converts an input to an output. Learners determine the work applied by the function machine to write a function rule. Questions accompany the function machine animation to guide individuals to conclusions.

Make the abstract a bit more concrete with an interactive that asks learners to slide an input value through a function to determine the output. Changing the slope and y-intercept allows them to see the how the output values change.

A five-question interactive boosts proficiency in working with binary numbers. Multiple-choice, short answer, and discussion questions challenge mathematicians to write numbers 25 through 31in exponential and binary form. An adjustable...

Learners use materials to build, investigate, and draw two-dimensional shapes (polygons). They combine the shapes they have built and draw from the pile to begin a round-robin activity to name and determine the attributes of a selection...

Compare and classify 2-D shapes! Kindergarteners inspect the attributes of plane shapes and examine shapes in everyday life. They label the circles, squares, rectangles, and triangles they find. This is the website where you can find the...

Time to learn about sundials. Scholars see how to build sundials after learning about Earth's rotation and its relation to time. The unit describes several different types of possible sundials, so choose the one that fits your needs — or...

Five questions make up an interactive all about whole-number exponents. Movable building blocks create a visual tool to aide mathematicians in answering multiple-choice and true or false problems. The interactive ends with a discussion...

Emerging engineers perform pre-lab calculations in this first of a three-part lesson on model building. They determine the forces of tension and compression in a truss. After completion of the worksheet, pupils will draw a draft of their...

Find the math in recipes. Young chefs will follow a recipe and investigate the total cost for materials. They measure amounts of food necessary for the recipe and compute the per person cost.

Young mathematicians draw, create, and describe different shapes using triangles. They discuss attributes of the original and created shapes. Pupils classify the created shapes and draw and write in mathematics journals to communicate...

Physics is phun in this lesson. Young physicists use a lightbox to test how and where light is refracted and reflected as it travels through transparent materials. Angles of incidence and refraction, sine of both angles, and the...
