Number Patterns and Systems of Equations

Help your class discover possible patterns in a sequence of numbers and then write an equation with a lesson that covers sequence notation and function notation. Graphs are used to represent the number patterns.

Explore nonlinear systems through graphs and algebra. High schoolers begin by examining the different types of quadratic functions and their possible intersections. They then use algebraic methods to solve systems containing various...

Number towers use addition or multiplication to ensure each level is equal. While this is common in factoring, it is often not used with algebraic equations. Solving these six questions relies on problem solving skills and being able to...

One thing that puzzles a lot of young algebrists is the factors in a word problem that are taken as "understood". This presentation on solving systems of linear inequalities does a great job walking the learner through how to tease those...

Solving systems of equations underpins much of advanced algebra, especially linear algebra. Developing an intuition for the kinds and descriptions of solutions is key for success in those later courses. This intuition is exactly what...

What volume of information about units of volume can your brain possibly hold? The third installment of an 11-part Math in Science video series introduces viewers to metric units of volume, using common objects as examples for...

Another method for solving systems of equations, in addition to graphing, is the focus of this video, as Sal demonstrates the substitution method. It's important to understand that there is more than one way to solve any problem,...

Provide an inconsistent example. Learners view an algebra video demonstrating how to solve a system of linear equations by graphing. The system does not have any solutions or is inconsistent. Scholars realize that the graphs of the two...

Can you determine the exact volume of a bottle based on the relative volume of other bottles? A series of four videos shows someone pouring fluid into bottles. Scholars must set up a system of equations to determine how much each bottle...

Find the pattern is the name of the game! Learners examine different patterns represented by numbers, shapes, and words. They must describe the pattern, predict the result in a given position, and find an equation that...
