Pupils investigate the connection between factors, zeros, and graphs of quadratic functions.  The instructional activity requires the TI-nspire handheld.

Students investigate the Pythagorean Theorem.  For this seventh through twelfth grade geometery lesson, students explore the Pythagorean Theorem and its converse and use it to find the length of the missing side of a right...

High Schoolers engage in a study of quadratic functions and focus upon the finding of equivalence and its connection between functions. They also practice factoring using the FOIL method while manipulating the equation. The lesson also...

Mathematicians measure intersecting lines-and circles, and create chords. In this geometry lesson, students explore interrior and exterior chords created by tangent and secant lines. These segments can be inside the circleor outside the...

Young scholars study chemistry.  In this laboratory lesson students watch the CSI episodes and investigate their laboratory techniques and discuss what they saw.

Students define vocabulary words. In this geometry instructional activity, students identify the graph as a line, ray or segments. They understand the properties of each and calculate the distance on a number line. 

Young scholars read an article to explain the reasoning behind theorems. In this calculus lesson, students understand the underlying principles of theorems and how it helps them make sense of the problems. They know why they do what they...

Create a human fraction to learn about division of exponents. Scholars develop the rule for division of exponents by being part of a human fraction to explore and justify the rule. They also consider zero exponents and negative exponents.

Learners take the abstract concept of binary representation and create a more tactile and concrete approach. Using egg cartons, they create a physical representation of binary numbers. The egg cartons become a tool to assist students in...

Students examine the built environment and infrastructures of their community by constructing contour equipment, using the equipment, and comparing their results to current topographical maps of the same area

Fit functions to data by using an interactive app. Individuals plot a scatter plot and then fit lines of best fit and regression curves to the data. The use of an app gives learners the opportunity to try out different functions to see...

Graphing conics made easy. Individuals use an interactive to graph conic sections. The app can handle circles, vertical and horizontal parabolas, ellipses, and vertical and horizontal hyperbolas.

Scholars see cross sections come to life using an app to investigate cross sections of three-dimensional solids. They look at prisms, pyramids, cylinders, cones, and double cones.

Students experiment with several chaotic simulation, they build a working definition of chaos. Students reinforce their knowledge of basic probability and percents. They are reminded of previous knowledge that is pertinent to this...

Students explore the concept of irregular fractals. In this irregular fractals lesson, students discuss how to find fractal dimensions through teacher led discussion. Students calculate fractal dimensions of various fractals.

Learners are introduced to the elimination method in Algebra. As a class, they solve two linear equations with two unknowns using this new method. They discuss the positive and negative aspects of using this method to solve problems. ...

Students examine graphs of three statistics and use basic math to compute their own. They evaluate the implications of manipulating data and whether statistics are appropriate for creating policy.

Study geometry through the concept of quilt design. High schoolers examine the geometric shapes in various quilts and then create their own quilts using geometric shapes that fit together. In the end, they write a paragraph to...

Students identify diagrams of quadrilaterals and circles by different names and classify the figures. They name the areas for each diagram and practice solving the formulas for each.

Students identify classes in their schedules and associate the class with the time of day it is held. They then name classes in sequential order according to the period during which it occurs.

Learners input data about the colors of their serving of M&M candies onto a spreadsheet. They create charts and graphs based on this information.

Students explore the concept of transformations.  For this transformation lesson, students use an applet that is an interactive absolute value graph applet.  Students manipulate the applet to examine the change in the function...

Students explore the coordinate plane. In this secondary mathematics lesson, students follow a set of directions to plot points in the coordinate plane.

Students locate objects using a Global Positioning System. In this global geography lesson plan, students explore latitude and longitude using a GPS in order to locate objects.
