Using elimination to find the point of intersection of two lines, students learn to solve systems of equation. They graph their solutions and use the TI to verify the solution.

Learners define and graph properties of linear equations. In this algebra lesson, students write systems of equations to represent functions. They relate linear equations to the real world.

Pupils solve polynomial functions by graphing. They factor rational expressions to find the roots of the equation and apply the rational zero theorem to find the zeros of a polynomial.

Students name the area formula and describe how it works. They use area formula to calculate the surface area of various objects. They use the area formula to design a floor plan of an apartment.

Students assess their own energy use to help develop an awareness of the different types of natural resources affected by consumers. Their calculations show them how much they are personally impacting the Earth. Very meaningful and...

Young scholars engage in a lesson which shows them that celestial navigation is the art and science of finding one's geographic position by means of astronomical observations, particularly by measuring altitudes of celestial objects -...

Students solve theoretical probability problems. In this algebra instructional activity, students apply the concept of probabilities to solving real life scenarios. They collect data and graph it using experimental probability.

Learners slice cones and identify the different conics formed. They then derive the formula to solve problems involving cones. Pull out the TI calculators to visualize the slicing and the different parts and properties created.

Third graders review formulas for area and perimeter in quadrilaterals. They arrange pre-cut twine on a centimeter graph paper to create non-congruent quadrilaterals. They calculate the perimeter and area of each form.

Pupils explore the concept of derivatives. They use implicit differentiation to determine points on a graph where a tangent line is horizontal, vertical, or oblique. Finally, learners find the derivative of a polynomial by...

Young scholars graph an equation and analyze the data. In this algebra lesson, students graph scatter plots and identify the line of best fit using positive correlation, negative correlation an d no correlation. They apply their data...

High schoolers analyze the numbers of male vs female administrators and teachers from their school. In this gender equality lesson plan, students use school yearbooks from the 1950's threw present to count how many male vs. female...

Students practice graphing and other math skills to track number of honeybee colonies present in United States since 1978, discuss major crops that are dependent on insect pollinators, and examine reasons for decline of United States...

Students study a variety of math concepts in the context of cooking up a meal. For this math lesson, students calculate surface area and volume. They draw and interpret different types of graphs.
