PROBLEMS/SOLUTIONS

Take young mathematicians' understanding of percents into the real world with this series of word problems. Involving a variety of contexts from calculating scores on math tests and savings account interest, to determining sale prices...

Your algebra learners will pick up some solid algebra problem solving skills and a plan of approach for some typical types of word problems in this scripted learning exercise that shows how to set up and organize each type of problem,...

Inequalities: when one solution just doesn't suffice. Individuals learn to write inequalities in real-world contexts and graph solution sets on the number line. All inequalities in the lesson are of the form x < c or x < c.

Use several skills to solve word problems leading to systems of equations. Scholars define variables and write equations to model situations described within word problems. Pupils solve the resulting system of linear equations using...

Is there one, none, or more? Through discussion or activity, scholars find the properties of an equation that will determine the number of solutions. They then use the properties discovered to figure out the number of solutions for a...

If at first you cannot graph, substitute. The lesson introduces the substitution method as a way to solve linear systems if the point of intersection is hard to determine from a graph. The 28th installment of a 33-part series finishes...

Solution stoichiometry ... reducing waste, one calculation at a time. Chemistry scholars examine the concepts and calculations involved in solution stoichiometry with a video from JFR Science. The narrator gives examples of when to use...

Use a table to find the solution set for an equation. Watch an instructor as she directs how to create ordered pairs using a given domain and check your answers using one of these ordered pairs. A practical video for anyone, student or...

Demonstrate how to solve the volume of solutions in a concentration. Then after many guided practice problems, scholars complete additional examples independently.

Given a replacement set of values, plug them in to find a solution set to this inequality expression.
