We use the Life of Fred series for math here at our Redstone Academy. We have been ever since the beginning. Here is our collection:
Yes, that's a college-level Statistics course. No, we haven't used it yet. Kevin ordered it for Connor, just because it seemed like he might be interested in it sooner rather than later. If you have ever watched a football game with Connor, you understand why.
But we have used all the other books. Apples through Jelly Beans are to be used from Kindergarten through 4th grade. Then come the three intermediate books: Kidneys, Liver and Mineshaft. Those are supposed to be for 4th to 6th grade. Afterwards begin the topic-specific books, like Fractions, which Connor just finished. He will begin with Decimals and Percents next year. Those are both part of the five-book Pre-Algebra series. Those five books are middle school math. So, Connor is really kind of ahead of his grade level in math, and he is doing great.
Lex is also above his grade level in the Fred books. He finished both Honey and Ice Cream this year, and those two, along with the last book in the elementary series, are the ones that really get into multiplication and division. Since there are only three books that really deal with multiplication and division, I'm going to re-do Honey and Ice Cream with him again next year before moving on to Jelly Beans and then the intermediate series. That sounds just perfect for the beginning of 3rd grade.
I'm looking forward to many more years with Fred. He's a funny little guy. There is even a high school level language arts course that we will probably investigate in the years to come.
