As we move on through Chapter 5, please be sure to refer back to your notes if you run into trouble. Here are a couple good sites that I found that break down the process of adding, subtracting, multiplying and dividing with fractions in a super-simple way. Check 'em out:
Add/subtract - http://www.math.com/school/subject1/lessons/S1U4L3GL.html
Multiply/divide - http://www.math.com/school/subject1/lessons/S1U4L4GL.html
Also, here are a couple of games that are simple, but are a great mind-jog for reviewing things like comparing and ordering fractions with different denominators, etc:
