Using Technology to Represent Mathematical Identities

It's obvious that different types of trees have different heights, right? Pupils quantify differences in the heights of two tree types given box-and-whisker plots. They use measures of variability, such as the interquartile range, to...

You can learn to graph as well as a calculator using calculus. The lesson introduces using derivatives to find critical points needed to graph polynomials. Pupils learn to find local maximums and minimums and intervals of increase and...

Equations can tell us a lot about graphs. Pupils begin by graphing exponential equations using technology. Based on the results, they see how different parts of the equation correspond to the graph.

There's zero reason not to use a helpful resource. Individuals use zeros to graph a cubic function on a coordinate plane. First, though, they must find the zeros from the factored form of the equation.

How do vectors help make problem solving more efficient? Math scholars use vectors to represent different phenomenon and calculate resultant vectors to answer questions. Problems vary from modeling airplane motion to the path of a robot. 

Create a constructionist approach to constructions. The lesson plan introduces the concept and tools of constructions. Pupils use worksheets to find a method that will perform the given constructions. The teacher guides the groups and...

What is the net effect when two waves interfere with each other? The lesson plan answers this question by helping the class visualize waves through graphing. Pupils graph individual waves and determine the effect of the interference...

Special right triangles give special information. Individuals learn how to find trigonometric ratios in all quadrants. This involves using special right triangles and the Pythagorean Theorem.

The future lies in mathematics. Given a linear equation that models a context, scholars use the model to predict future values. They must perform substitution to determine the required output value.

This video introduces the basics of trigonometry. It starts by defining a right triangle and showing two different examples of finding the ratios of sine, cosine, and tangent using the SOH-CAH-TOA mnemonic. This resource could be used as...
