The CyberSquad uses algebra to figure out how many gleamers they need and how many power glows are produced by each gleamer as they must power up a Cyberspace ship in this video from Cyberchase. [1:43]

In Spanish. Examples and practice problems on balancing simple, one variable equations.

[Free Registration/Login may be required to access all resource tools.] In this lesson students learn how to solve compound inequalities. Students watch a video tutorial, explore guided notes and attempt practice problems.

In Spanish. Clear step by step directions, explanations and example problems of quadratic equations. Explains factorization, the quadratic formula, and completing the square.

The premise of this problem is simple - students must find three whole numbers with three different sums when they are added in pairs. To do this, they set up a system of linear equations in three variables. Aligns with A-REI.C.6.

The purpose of this task is to give students the opportunity to make connections between equations and the geometry of the graphs. Aligns with A-REI.C.7and A-REI.D.10.

This activity focuses on strengthening student understanding of connections among graphical, tabular, and algebraic representations of simple linear functions. They enter a simple program that allows them to determine the equations for...

[Free Registration/Login Required] In this Flipchart students are posed with a seemingly simple problem: guessing the correct number of handshakes possible amongst a group of eight students. Participants then solve the problem visually...

This problem allows students to see words that can describe the expression from part (c) of "5.OA Watch out for Parentheses." Additionally, the words (add, sum) and (product, multiply) are all strategically used so that the student can...
