Students graph systems of equation. In this calculus lesson, students graph their lines on a TI calculator. They identify the point of intersection and the type of solution.

Mathematicians use a symmetric secant line to prove the derivative at a point. In this trigonometry lesson, students create secant lines on the navigator to analyze the derivative. They move the lines around and make observations.

Students identify triangles as similar or congruent. In this geometry lesson, students drag triangles around on the navigator to see the effect of different angles on the shape of the triangle. They discuss angle similarity and angle...

Learn how to calculate the length and midsegments of triangles. Students differentiate between similar and congruent triangles. They create a spreadsheet with their findings.

Mathematicians compare triangles at different scales. For this geometry lesson, students calculate the area and perimeter of triangles. They use the Ti to make observation of the change that takes place as the triangles are dilated.

Your class will investigate the relationship among different triangles. This geometry instructional activity, demonstrates how to make a connection between triangles and the Pythagorean Theorem. They identify the missing side or angle of...

Have fun calculating angles for different polygons. The class differentiate the relationship between the interior and exterior angles of polygons. They discuss linear pair as it related the polygons and their angles. This is done as they...

Students perform transformations and translations using polygons. In this geometry lesson, students perform transformations on a coordinate plane. They identify the image and pre-image of each figure.

Students perform transformations on their graphs. In this algebra lesson, students identify the pre-image and image. They find and identify congruent shapes and isometry.

How do you identify the domain and range of the function? As learners find out it's as easy as creating a graph. They'll identify the domain and range of a relation from its graph, write symbolic expressions describing the relationship...

High schoolers factor quadratic equations. In this algebra lesson plan, students identify the factors and use them to graph the parabola. They find the parameters and vertex of each graph.

Students solve quadratic equations. For this algebra lesson, students factor and graph quadratic functions. they use the properties of quadratics to calculate the distance.

Students find the roots of quadratic equations. In this algebra lesson, students solve radical equations and identify the positive and negative roots. They graph and analyze their functions.

Young scholars investigate the Napoleon triangle theory. In this polygon lesson, students  differentiate between the boundary points, interior and lattice point of a polygon. They apply concepts of equilateral triangles to...

Students calculate gas prices. In this transportation instructional activity, students tally the mileage and gas costs of their car for one months. They figure out how much was spent on gas and create a graph showing average gas prices...

Students explore the coral reef. For this food chain lesson, students study the plants and animals of the coral reef and how they each play a role in that ecosystem. They participate in a class play to demonstrate the types of animals in...

Students explore food chains. In this ecosystem lesson plan, students discover how plants and animals rely on each other for survival. Students research the rocky shore ecosystem and create a skit representing the ecosystem.

Students explore Native American tribes in Maryland. In this Maryland history lesson, students investigate Native American tribes in a webquest. After completing the webquest students create a triarama.

Young scholars explain the reason for the changes in season. In this lesson examining the relationship between the Earth and the Sun, students use an applet to discover how the alignment of the Earth and the Sun cause the change in...

Students walk marked paths as they simulate the orbit of the planets.  In this solar system lesson, students recognize the relationship between the sun and the planets.  Students visualize how the phases of the moon are seen.

Students design and build their own car. In this physics lesson, students collect data to determine the speed of the car. They plot the data on the graph analyze the relationship between variables.

Students compute the length of time it will take to save enough money to purchase a yo-yo. In this math lesson, students create a design with pennies and write the associated linear equation. In this linear equations lesson, students use...

Students calculate the volume of different polygons. For this geometry lesson, students identify the relationship between base and height. They calculate the area of each prism and cylinder.

Students read about potential violent relationships and beliefs about dating.  In this relationship lesson students use graphs to examine data about healthy realtionshipsand draw conclusions on their results.
