Life of Fred
We've tried them all! We started homeschooling in 2005 with a 4th grader, 5th grader and a 6th grader!
We switched to Life of Fred Maths this year after trying BJU(4th-5th grade), Saxon books & Teaching Tapes(6th-7th) Math-U-See(8th-9th), ALEKS(9th-10th), 'Key to' curriculum(4th-9th), & Jacobs Algebra(9th-10th).
My 15-yr old who HATES math says, and I quote, "I dislike Life of Fred the LEAST of any math I've ever done!" Coming from her, that's quite a compliment!
My 17 yr-old also wants to continue with LOF through the rest of high school next year; the only dissenting voice is my 16 year old who complains that Life of Fred is too hard for her. After looking through the Life of Fred lessons, and looking at our previous curricula, I know WHY it seems hard for her. Life of Fred is more advanced than the curricula she has been used to.
I only wish I known about Life of Fred when we began homeschooling, and could have used it from the beginning!
