New ReviewTake a step back to Algebra II. The first lesson in a series of 23 asks scholars to remember working with quadratic equations with complex solutions. Pupils apply polynomial identities to complex numbers and work examples that show how...

How high will it fly? Pairs build straw rockets and launch them at different angles and determine the height and horizontal distance of the flight path. Teams make conjectures about how the angle affects the measured distances and use...

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. 

What makes this resource special? The amazing answer key that comes with worked out solutions and notes for each problem. Practice problems include all topics ranging from linear systems to simplifying exponential expressions. The packet...

While there are many types of equations to solve, the main focus here is on quadratics. Starting with a quick review of the different methods, learners are guided through the solving process and are challenged to solve higher level of...

Summer projects are key to helping leaners stay proficient in math skills. Here is a project that reinforces Algebra II skills. Including five parts, the project explores graphing functions and quadratic equations such as the standard...

Make math enjoyable while playing a favorite game! Learners fly their way through quadratic equations as they predict the flight path of an Angry Birds character. The lesson plan incorporates some play time of the game, followed by an...

This resource has everything you need to know about solving quadratic equations. Factoring, completing the square, the quadratic formula, and using the discriminant are all there with with worked out examples and a 25 problem worksheet...

In need of a practice worksheet solving quadratic equations using the formula? Have no fear, we have one for you! This worksheet provides the formula at the top with 14 questions following using a variety of leading coefficients. 

Through a variety of physical and theoretical situations, learners are led through the development of some of the deepest concepts in high school mathematics. Complex numbers, the fundamental theorem of algebra and rational exponents...

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,...

This problem is sure to get your young mathematicians thinking. The idea sounds simple: one equation, solve it as many ways as you can. This is meant to get at a deeper understanding of solving quadratic equations, including some more...

Sal explains how helping his young cousins with their math skills inspired him to make this series of videos, so he can help a bunch of people pass the SAT. In this video, he covers exponents, quadratics, and parabolas in problems 5-9 on...

Sal clarifies that doing a math problem the correct way isn't really the correct way to do it on the SAT. If students find this statement confusing, they will understand Sal's point after watching him work quickly and efficiently through...

Here, Sal begins section 6 on page 407 of The Official SAT Study Guide, focusing on problems 1-4 in this video. He clarifies that SAT questions are "tricky, but really fast" problems that shouldn't take a lot of time to solve. To prove...

Play ball! High schoolers explore the concept of quadratic equations through modeling how shooting a basketball can be expressed as a quadratic function. They impose a coordinate grid on the path of a shooting basketball and determine...

High schoolers graph functions that are given, and then they write the equations for the completed graphs. There are several problems included, and they are designed to be used without calculators.

With his trusty graphing calculator, Sal begins his lecture on solving quadratic functions by graphing. The video is a good way to show young mathematicians not only how to use the graphing calculator (which Sal describes as "archaic"...
