As if solving equations with an x isn't tricky enough, now they add a y, too? A pre-assessment gauges the knowledge of your classes related to systems. They are asked to solve graphically and algebraically and to solve word problems. 

It's time to show off what they learned! The final lesson in the series is a review worksheet on the topics learned throughout the unit. Scholars solve systems of equations using graphic and algebraic methods, solve system-based word...

Create an understanding of solving problems that require more than one equation. The lesson introduces the concept of systems of linear equations by using a familiar situation of constant rate problems. Pupils compare the graphs of...

How do you convert from one measurement to another? Pupils use unit rates to convert measurements from one unit to another in the 21st segment in a 29-part series. They convert within the same system to solve length, capacity, weight,...

Expose your students to the differences and vocabulary associated with both U.S. Customary Units and Metric Units. Sal defines 14 different terms of measure and then sorts them into two categories. He has lots of little side notes that...

Math scholars with a basic grasp on units of measure will appreciate this video. Sal breaks down the process needed to convert between metric units. He defines kilo, hecto, and deka than uses that framework to assist him in determining...

An example of unit conversion using drug dosage is the focus of this video. Sal, the all-knowing pre-algebra guide, takes a problem from a nursing class to show the process of unit conversion within an algebraic expression. This helpful...

As Mia and RJ discuss measurement, your class is introduced to the customary and metric systems for measuring mass, capacity, weight, and length. Temperature scales are also introduced. This resource can help set the foundation for later...

Teenagers in this engaging video explore different ancient measurement systems. Footage of the teens and computer animations combine to stimulate viewers' interest. The metric system is interchangeably referred to as the decimal system...

A speed limit sign in Europe might be misleading if you don't understand different unit systems. A video presentation describes measurement units for length, mass, and capacity to help viewers differentiate between them. The...
