There tends to be a certain amount of creativity when it comes to teaching. A challenge presents with each lesson to find ways to help the information sink in, or even to present it in a clear manner. I find it personally helpful to glean some suggestions for spicing up lessons or reinforcing subject matter from other homeschool moms (mainly because I lack that critical creativity gene). Yup, I am completely unashamed to admit that I don't reinvent the wheel each time I teach my kids a lesson. If you found a great way to teach something and I've heard about it, I just might use it. Please think of it as less of plagiarism and more of admiration.
Ellen McHenry's Basement Workshop is one site I have found with some great downloads to help reinforce lessons and teach various concepts. As I understand it, Mrs. McHenry has had a varied past with teaching and homeschooling. On her website she shares lesson plans, activities, and games that have worked for her students. Several different subjects are represented. There are a few links for each subject, but it appears the site is being added to from time to time - so check back.
