Posted on April 13, by Passy Image Source: We have one for you a bit later in this lesson. Word Problems need to be turned into Algebra Expressions so that we can do mathematics on them, and work out number answers. Or write a Computer App that gets the answer.

This article explains some of those relationships. I was asked, I need an easy and helpful way to teach writing equations. Helen has 2 inches of hair cut off each time she goes to the hair salon. If h equals the length of hair before she cuts it and c equals the length of hair after she cuts it, which equation would you use to find the length of Helen's hair after she visit the hair salon?

The first thing I do when trying to figure out how to teach something is to analyze my own thinking. How do I think when solving this problem? What are the steps and fine details?

It is these details and steps that I may do automatically that I need to explain to students to help them. Seeing the quantities and their relationship instead of numbers In this problem there is seemingly lots of information, but really it's about recognizing quantities and the simple relationship between them.

This is of course the exact same task as translating a situation explained in words into a mathematical expression using symbols. Children manifest the difficulty in this task when they read a simple word problem and then ask, "Do I go this times this, or do I divide?

They need to step out of the 5, 2, 10,or any others numbers in the problem, and see the general quantities involved and how those are related to each other.

In very simple word problems that relationship usually involves just one of the four basic operations.

Then in algebra, there may be more quantities and more operations between them. Examples of addition word problems Example. Jenny has 7 marbles and Kenny has 5. How many do they have together?

The quantities here are Jenny's marbles, Kenny's marbles, and total marbles.Unit 13 - Systems of Equations. Systems Quiz # Systems Quiz # Practice Tests (Study Guides)!!!
