To Be Linear or Not to be Linear, That is the Question

Nothing fancy here ... just your run-of-the-mill Algebra party! Learners explore the patterns of linear functions while designing seating arrangements for a dinner party. Comparing the number of tables to the perimeter of the combined...

Did I cause that? The lesson provides definitions of correlation and causation along with types of causation. Within the presentation, pupils analyze erroneous conclusions based upon correlation. Groups then develop a newscast based upon...

Build a square physically, with representations, and, finally, algebraically. The lesson plan takes the class through the concept of completing the square first concretely, secondly by using representations, and finally via abstract...

What does it mean for two vectors to be linearly independent? The resource presents the basics of basis vectors and linear combinations. The third video in the 15-part series provides a definition of linear independence in terms of the...

Your graphing calculator can do lots of amazing things, even solve equations graphically. Young mathematicians learn to solve linear equations by using a graphing calculator. The informative YouTube video shows them how to apply the Zero...

Connect a linear system to a linear model and watch how the system is solved step-by-step. The equation and visual representations are solved next to each other to see how each step relates to the equation and model. This is a great way...

Just let the technology do it. Pupils develop a spreadsheet to graph linear equations. By creating an input/output table, learners are able to create a scatter plot and connect the points to graph a line. Scholars use textbook equations...

To complete homework or not to complete homework ... that is the question. Decide whether it makes a difference on finals by doing homework. Individuals create a scatter plot and find a line of best fit for data on the percent of...

Step up to the challenge of finding the slope of stairs. Groups measure the rise and run of a set of stairs. They share their data with the rest of the class to determine a class average for the slope of the stairs.

Ah, the dreaded systems of equations word problem. Probably one of the best ways to connect algebra to the real-world, here is a video that goes through the steps on how to detect key words and create two equations that model the scenario.
