Comparing Exponential and Power Functions
High schoolers compare and contrast exponential and power functions. In this precalculus lesson, students identify the value of x, using the graph as a visual. They compare functions with base of greater than one, to base of less than one.

Rose Curve
Arcsine will be better understood and applied through prediction the number of petals on a rose curve using polar equations. Students relate rose curve to siusoidal functions using the Ti navigator.
Curated OER
Trains in Motion
Students compare two object as they find the distance between them. In this geometry lesson, students create an equation describing the distance of time as a function. They use the navigator to observe the distance.

Exploring Areas of Irregular Polygons
Young scholars solve for the area of different polygons. In this geometry lesson, students identify and differentiate between regular and irregular polygons. They use properties of irregular polygons to solve problems.
Curated OER
Computing with Mathematical Formulas
Students solve problems using formulas. In this algebra lesson plan, students evaluate numbers using substitution. They graph their answers using a TI and discuss the outcome.
Curated OER
Solving Systems by the Elimination Method
Pupils solve equations by elimination and use the TI to graph the lines and find the point of intersection.

Managing Nutrients in Livestock Manure
Livestock managers reinforce math and science skills while learning about the nutrients found in manure. They predict which animal produces the largest amount and which animal's manure contains the most nitrogen. Finally, they compare...
Curated OER
Linear Approximation
Pupils practice examining the tangent to a function to estimate the value of the function near the point of tangency. They view errors associated with those approximations, determine overestimates and find intervals that guarantee a...
