Here is a simplified guide on how to change between different ways to write fractions. It contains examples and directions to convert:
a fraction to a decimal
a fraction to a percent
a decimal to a fraction
a decimal to a percent
a percent to a decimal
a percent to a fraction
Also included are directions on an absolutely rockin' foldable study guide. After some practice to master the thing, you can teach how to do these, but I always premake them because there are a always a few kids who need help and hold us up.
Now this foldable might seem like a pain, but I promise it works great. The kids love them and want to redo them to make them perfect. Then they rewrite it to make it smaller or whatever. Think that helps them learn? You bet! They love to pull them out to consult and use. If you laminate one side of the big page, they last forever. I have not seen this one many places and can't find it at all with a Google, but it is so effective.
