If you Home school or want to freshen up your skills to help your kids with their homework this year you can download this book for free on Amazon. Just thought I would share it with my readers. I downloaded it for my Kindle Fire this morning and looked it over using my cloud reader. I think it will come in handy this year. I am not sure how long it will be free as the regular price is $7.99 so if you want it you may want to get it now. My children go to public school. We still have lots of homework to help them with so this will come in handy.
