High schoolers define exponential functions and graph the equation. In this algebra lesson plan, students discuss exponential growth and decay as they graph their functions. They differentiate between the base of growth and decay.

Students graph linear and exponential equations. In this algebra lesson, students differentiate between linear and exponential equations. They relate it to the real world.

Teach your class how to solve problems using the triangle sum theorem. In this geometry lesson, high schoolers identify the missing angles in a triangle using the sum theorem. They graph triangles on the TI and moves the sides around to...

Students identify important properties of triangles. In this geometry lesson plan, students differentiate between medians, bisectors and altitudes in a triangle. They identify the properties of these important segments.

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

Using a TI Navigator to drag quadrilaterals around to create different shapes, students learn how to draw midpoints in their quadrilaterals. In this geometry lesson, students solve problems using the properties of quadrilaterals. 

Using TI-Nspire, scholars rewrite quadratic expressions by completing the square. They change the equation into vertex form.  By the end of this instructional activity, they should be able to change any quadratic equation into...

Students solve systems of inequalities. In this lesson plan, they identify the solution of the two lines and shade the solution. They identify the boundary line and the region representing the solution.

High schoolers solve problems with matrices. In this algebra lesson, students find the inverse of a matrix. They calculate the determinant and solve for the identity.

Students solve systems of equations. In this algebra lesson, students use matrices to solve linear equations. They use reduced row echelon-form and scalar multiplier to simplify the matrices completely.

Young mathematicians calculate the area of polygons in this algebra lesson. They find the determinant as they calculate the areas for triangles and quadrilaterals. They also use scalar multiplication to find the determinant.

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

Statisticians analyze different samples to find independent and dependent events. In this probability lesson, pupils predict the outcome and then calculate the real outcome. They create a tree diagram to help predict the probability of...

Students research and discuss the societal changes during the Civil War as it relates to various parts of southern society. In this southern society during the civil war lesson, students examine what life was like for slaves during the...

Students compare their travel needs to homesteaders from the late 1800's in this multi-lesson unit. Students analyze a historic document, explain modes of transportation of the homesteaders, and articulate the personal and economic...

Students are introduced to the proper ways to deal with conflict at home. In groups, they define family based on what it means to them and identify factors that lead to a breakdown in communications. They participate in role-playing...

Students describe a pretend animal. They read "The After School Monster." Students read other books and discuss whether or not the characters are real. Students make a drawing of a pretend animal and of a real animal. They make up a...

Students collect weed seeds from three varieties of weeds (knapweed, thistle, or toadflax, for example they may choose others in addition to the spotted knapweed.) They sterilize soil for thirty containers, plant seeds in sterile soil,...

Learners study weather using a graphing calculator in this lesson plan. They collect data for temperature and relative humidity for every hour over a day from the newspaper, then place the data in their handheld calculator and examine it...

Learners study the concept of central tendency in this data collection for bar graph activity. They collect data outside as instructed and organize it into a bar graphs, then they list in specific groups the labels that appear on the...

Learners analyze data using bar graphs and the TI in this statistics lesson. They investigate quick polls and graph the data using different properties of statistics. This assignment requires a TI Navigator.

High schoolers explore algebraic expressions in this Algebra I lesson plan. They evaluate expressions using paper and pencil and then use the TI-83 to provide immediate reinforcements.

Learners explore scatter plots in this algebra lesson. They create a scatter plot from their guesses regarding a famous person’s birth date and the actual birth date then they examine and interpret the results of their graph.

In this Algebra II activity, students explore the connection between the factored form of a quadratics and the zero of a function. Students use a graphing calculator to verify factoring numerically and graphically.
