Once you determine the variables they are using, make the notation public (write it on the whiteboard). You can allow an extra point if the expression is correct. If students have invented their own notation such as □ + 3, stick with it for the time being. Eventually, introduce sequence...

Let's look at an example of solving an algebraic expression using these rules. 4x - 6 = 10 To get 4x by itself we add 6 to both sides of the equation. This gets the 4x by itself giving us 4x = 16 Now we can divide both sides by 4 to get x by itself thus solving the...
Writing the Algebraic Expression We need to write out an algebraic expression that we can evaluate to find our answer. To write our algebraic expression, we carefully read the problem to figure out what our important numbers are and what kind of operation we are dealing with. ...
