Most of the pairs had figured out the correct answer to both problems and where a different answer had been reached, sharing the thinking in the group of four resolved the issue. “Okay, good work with this. We can use this strategy to think through some of the more dense sections in the math textbook, too, not just with word problems.

For example, students can set up and solve a proportion that finds the height of an object by using similar triangles. Select problems which have variables in the denominator of the fractions. Use a math textbook as a reference to provide students with more opportunities to practice solving application problems using proportional reasoning.

Three by three systems of linear equations are also used to solve real-life problems. The given problem is expressed as a system of linear equations and then solved to determine the value of the variables. Sometimes, the system will consist of three equations but not every equation will have three variables. Example three is one such problem.
Practice in Identifying Variables
Oct 28, 2010 · Fred Rogers wanted to test a new “sing-along" method to teach math to fourth graders (e.g. "I Love to Multiply to the tune of God Bless America). He used the sing-along method in his first period class. His sixth period students continued solving math problems with the old method.

Confounding Variables: For each selection, identify the one serious confounding factor that threatens the experiment’s validity. Then, suggest how the confounded factor could be controlled. Fred Rogers wanted to test a new sing-along method to teach math to fourth graders (e.g. “I Love to Multiply” to the tune of God Bless America).
Solving Algebra Equations with Variables on Both Sides
Algebra 1: 3.4 SOLVING EQUATIONS WITH VARIABLES ON BOTH SIDES. Goal: Get ONE variable alone on one side of = sign. Use Distributive Property, if necessary. Combine like terms, if necessary. Move one variable by adding its inverse to both sides of =. Solve as usual.

More Word Problems in Point-slope form. Sometimes instead of giving a rate, a word problem gives two relationships at different points in time between variables. This kind of problem is giving you two points. You must find the slope and then use one of the points to write an equation. 1.
