PRODUCT DESCRIPTION

As my algebra students learn to solve equations of greater complexity, I find it helps them to use the analogy of a "balance" or "seesaw" to help them understand that if you take the same amount off of both sides of balance, the two sides remain equal in weight.

I also find it helpful for students in these early stages to have a "recipe" for solving equations, so this worksheet gives them a step-by-step process to use to solve basic linear equations.

One technique listed on this sheet is the concept of using the "order of operations ladder," which is simply a record of the operations "being done" to a variable, with a corresponding "inverse operation".

------ Please hover over thumbnail image #2 -------

For example, to solve the equation 5x + 3 = 13, the order of operations ladder would have the operations "multiply by 5" and "add three" listed on the left, and climbing back up the right side of the ladder, the operations "subtract 3" and "divide by 5" would be listed. Students simply "climb up the ladder" to solve the equation: subtract 3 from both sides, and then divide both sides by 5.

I use this activity within cooperative groups, and I circulate to make sure they are getting the purpose of the questions.

The file includes spiral review problems.

This worksheet is intended for students to show their work on a separate sheet of paper.

Please download the pdf preview file first, so you can see exactly what's included; the product file is a word document, which you may personalize for your students.

Immediately before this worksheet, I use the worksheet named 'Area and Perimeter Problem-Solving worksheet with Answer Key' (http://www.teacherspayteachers.com/Product/Area-and-Perimeter-Problem-Solving-worksheet-with-Answer-Key-366406), and immediately after this worksheet, I use the worksheet named 'Volume and Surface Area Boxes and Cylinders Fall 2013' (http://www.teacherspayteachers.com/Product/Volume-and-Surface-Area-Boxes-and-Cylinders-Fall-2013-1125171)
