What's Below Zero?

Captivate your class by having them find the value of their names, different zoo animals, musical instruments, etc.,with a mental math lesson plan. Using the coding formula listed, children learn to fluently estimate and calculate simple...

What does order of operations have to do with solving equations? A video explains solving two-step equations using a do/undo chart. Learners recognize the operations within an equation and use inverse operations to undo those operations. 

Where did all these variables come from, anyway? The previous lessons in the series ask learners to solve multi-step equations using the distributive property, combining like terms, and using inverse operations. Now scholars solve...

"The neat thing about completing the square is that it will always work," Sal explains, "no matter how crazy the problem is." A basic overview of how to complete the square, this video provides a good background for both beginning and...

Here is an equation in which the first step is to use the distributive property to get rid of the parenthesis. Then it is solved for the variables. Since there are variables on both sides of the equation, it is important to verify the...

Sal demonstrates how to solve an equation. He begins by saying that the variable needs to be isolated. He shows how to move numbers on either side of the equal sign to isolate the variable. He also shows how to verify answers by plugging...

Here is an equation in which the first step is to use the distributive property to remove the parenthesis. Then, it is solved for the variables. Since there are variables on both sides of the equation, it is important to verify the...

Getting a meal, side dish, drink, and dessert can be delicious—but it can be expensive too! Practice addition and subtraction with money in a lesson that focuses on a sample menu, complete with task cards and word problems.

One of the many methods of solving quadratic equations is graphing. A video lesson first demonstrates graphing a quadratic function using an input-output table. After graphing the parabola, the instructor makes the connection between the...
