Table the decision to land. Pupils form flight crews by matching up different representations of linear equations. Given a set of coordinates for an airstrip, the crews determine the equation of the line that will position their planes...

A neat and organized formula handout makes the circle go round, doesn't it? Full of higher algebra topics, formulas and rules, graphs and definitions—there is a way to support everyone in Algebra II or Pre-Calculus. 

This resource should be called "All About Lines, and Then Some!". Packed full of all the key components of linear functions, learners review how to set up different equations, find intercepts, and graph. All the main topics are included...

Need a helping hand in Algebra I? How about a giant, super-sized worksheet packet? Here is a resource that has worksheets for virtually every concept with some accompanying examples. 

Carryout the lesson to determine the cost of pizza toppings from a Domino's Pizza® website while creating a linear model. Learners look through real data—and even create their own pizza—to determine the cost of each topping. They explore...

In this video, we create an equation and graph to show a linear relationship based on the word problem. This is good example for algebra and pre-algebra learners to help gain an understanding of creating equations, and graphing...

This video explores a basic linear cost equation. Given a rate-per-photo and a fixed-one time cost, write a function that represents the amount a customer would pay for x number of photos.

Viewers play a game with Sal, in which he presents three different data sets that come from either linear, quadratic, or exponential functions. In solving this puzzle, Sal manages to not only provide a strong definition of each function,...

Pushing through to problems 11-12 on page 398 of The Official SAT Study Guide, Sal goes into comprehensive detail on each problem. Problem 11 involves geometry, including the function of pi, and problem 12 involves non-constant slopes....

Sal finishes problem 10 in this video, as well as problems 11-13 on page 735. Students can practice skills such as linear functions, slopes, and calculating permutations. Problem 12 allows viewers to see the process of elimination in...

Graphs tell a story, and in this activity learners explore different graphs.They analyze slope and rate of change from the graphs and answer questions about the information they represent. This lesson even contains extensions for more...

High schoolers determine the linear equations of the density of water and oil by collecting data on the mass of various volumes of each liquid. They construct scatter plots from the data and use these to write the linear equations for...
