If fractions are taught correctly, they are fun and easy to learn. Most texts move children too quickly into adding with unlike denominators. I found that when I used fraction circles (manipulatives) and spent plenty of time on adding and subtracting with like denominators, children moved easily to unlike denominators, because they understood how fractions work. Fraction kits for each child or pair of children are essential. They are available commercially or you can make your own.
I started to write a whole book on this years ago, but did not finish it. Nevertheless, I've had numerous requests for what I did complete. One of the holdups has been that I've not found a font that works well for creating the worksheets, so they are done by hand. If any of you know of a font I could use, please let me know! In the meantime, you can use these to get started. Note that the worksheets are in PDF, so make sure you have Acrobat Reader installed. (Go to HELP for help.)
I don't have lessons and worksheets for every concept, but once you're off to a good start, you can use commercially available materials. You can present more than one concept a day if students can handle it. The first lessons are the most important, which is why I wrote scripted lessons for them. You may learn some teaching techniques by seeing how I scripted the lessons, too!
Spend plenty of time on the basic concepts, and the rest will fall quickly into place. Although my students were "behind" other classes initially, they finished the unit first and remembered what they learned.
