When looking for homeschooling resources I find it is best to cast large net. Trying out new worksheets and methods is a good way in the beginning to find out what works. Good online worksheet/workbook resource is www.education.com. It is free to join, and download about 10 free worksheets a month. If you prefer to upgrade your account you get unlimited downloads for just $3.99 a month, which is not bad because there are thousands of available worksheets. In addition to the worksheets they offer over 300 printable workbooks. If you like online-game educational based tools they also have a $5.99 a month program for this as well.
The website is easy to search and the materials are endless. I recommend trying it out with a basic membership for a month. Get your free 10 downloads and see how you like it. I like using the worksheets as supplements in math when the workbook we are using currently gets boring. Or if I need extra worksheets in science or grammar. Education.com is a good online resource worth taking a look it.
