Curveball vs. Fastball

Challenge the class to utilize their knowledge of linear and quadratic functions to determine the intersection of the parent quadratic graph and linear proportional graphs. Using the pattern for the solutions, individuals develop a...

Show your pupils that perimeter is linear and area is quadratic in nature with a short assessment task that requests learners to connect the graph and equation to a description about perimeter or area. Scholars then provide a...

Learners solve and complete 22 various types of problems. First, they find the gradients of the lines and plot the given points. Then, they complete the table of values for each equation and use the table to draw the graph. 

Though Sal expects that viewers are "reasonably familiar" with square roots, he takes this opportunity to explain some of the notation, and how to graph square root functions. He uses a graphing calculator from my.hrw.com/math06 to...

There may be a right answer, but there isn't one right way to solve the problem. This video goes through a word problem and solves it in three ways: algebraically, numerically, and graphically. Go step by step as the narrator explains...

After defining intercept, Sal solves a simple equation to identify each intercept and then plots the line on a graph. This video would quite nicely complement an introductory lesson on graphing.

Take your kids on a tour of graphing rational functions. Using this TI instructional activity, high schoolers identify the end behavior of their functions. They find the domain and range, describe end behavior, and look at asymptotes and...

Making conclusions from graphs doesn't need to seem like magic. Learners explore an interactive lesson on reading graphs to strengthen their skills. The content discusses how to read the axes of a graph and draw conclusions based on the...

Middle schoolers explore the concept of slope in numerous ways and start to look at simple linear equations. They describe the slope in a variety of ways such as the steepness of a line, developing a ratio, using graphs, using similar...

Here's a very detailed, step-by-step activity for students to do to learn about the relationship between the factored form of a polynomial function and its graph. Calculator instructions for the TI-83 are given, right down to the screen...
