Can you solve this problem? How do you know in what order various operations need to be applied to both sides of an equation?
Giving the students a trick about reading through all the directions is unintimidating and proves a point in an amusing way. This process is like peeling back an onion layer by layer.
Giving the students a trick about reading through all the directions is unintimidating and proves a point in an amusing way. The operation symbol to the right of a step indicates what operation was applied to both sides of the equation.
This can be difficult for some students.
Experienced teachers know that some students seem to have a natural feel of how to solve an equation. They just know how and when an operation should be applied to both sides of the equation. Capable math students may not be fully aware of why they are using a particular strategy to solve an equation, but they know.– Bruce, Anaheim, CA
Oct 5, - Today I want to explain how to teach problem solving by working backwards. Help kids learn and apply this useful problem solving strategy: working backwards! *Please Note: This post contains affiliate links which help support the work of this site.

Students who struggle solving problems quotes for kids solving basic equations ask questions like the following: How do you know whether to add or subtract the same number to both sides of work backwards problem solving strategy equation equation? How do you know whether to multiply or backwaards both sides of the equation by the same number?
How do you know in what order various operations need to be applied to both sides of an equation? The purpose of this post is to provide answers to these types of questions. Readers who have read the posts Inverses of Relations and Functions and Inverse of a Matrix will immediately see the connection between those posts and this post.
These free handouts and many more can also be accessed by visiting mathteachersresource. When solving different types of equations, I routinely ask my students to identify the type of equation being solved. When students can identify the type of equation being solved and know the basic algorithm to solve xolving type of equation, they can work backwards problem solving strategy equation and efficiently solve the equation; no strahegy time. In application problems, solving an equation is usually just one strategt step in finding a solution of a problem.
Case 1 equations are equations in which the variable appears only once in the equation. I use the following analogy to explain the basic reasoning behind the work backwards method: Suppose that you have established a base camp on a camping trip and take a day hike in the woods. Work backwards problem solving strategy equation can always get back to your base camp by simplify reversing your steps. Sample case 1 equations are shown in the text box below.
It takes a while for students to remember that equations involving the squaring or absolute value operations can have two solutions or no solutions.
From personal experience, the work backwards method as presented in this post is effective with both low and high ability students. The text box below gives five examples of case 1 equation types.
When solving for a variable in terms of other variables, think of the other variables as constants. After looking at specific examples of each type of operation, most students quickly develop an understanding of what reversing an operation means.
The text box below gives a work backwards problem solving strategy equation of common work backwards problem solving strategy equation and the corresponding inverse operation. Note that the reciprocal operation is its own reverse or inverse operation. Step1 Recognize that an equation describes a process that starts with an unknown value of a variable, then performs a series of back-to-back write a personal essay on any topic operations, according to the order of operation rules.
Equation solve plans are road maps that lead to the solution of an equation. The student now knows what operation needs to be applied to both sides of the equation and when the operation needs to be applied. Initially, I require beginning students to explicitly state the equation solve plan as shown in the examples below where the solve plan is described in a box to the left of the list of equations. The equation solve plan is the series of back-to-back operations in the equation that are performed, according to the order of operation rules, on the variable being solved for.
Step 2 Follow the equation solve plan in reverse order from the last step to the first step. At each step, apply the reverse or inverse operation to both sides of the equation. Students need to learn to interpret what they are reading and draw out information. This can be difficult for some students.
Each month I am tacking a different problem solving strategy this month it is working backwards. Working backwards is sometimes the best strategy and one of the most difficult for students to understand. I saw numbers, key words and started putting things together but not always correctly.
Also being dyslexic it was hard enough reading the information let alone interpreting it and then working backwards and apply inverse operations. When introducing the different types of problem solving strategies; looking for patterns, make a work backwards problem solving strategy equation, draw a picture, guess and check, and working backwards, working backwards can sometimes be a fun work backwards problem solving strategy equation to start first.
Giving the students a trick about reading through all the directions is unintimidating and proves a point in an amusing way. Ancient greece democracy essay worksheets are a great way to get students to read all the directions take in all the information and then work from there.
After doing these worksheets apply working backwards to math. Our first goal in any problem is to read the whole problem.
