We took our daughter out of public school at the end of last year in 4th grade. She was struggling, getting 10% on math tests and average 2 out 4 on her report card. We did Teaching Textbooks Grade 4 over the summer and caught her up so she could start 5th grade in September. She has gained confidence and now she is getting 90%-100% on her daily work and tests as well on this program. This program is made her more motivated as well. Her frustration level is diminished and she now knows she can do Math! We will use Teaching Textbooks through high school!
This math program has an excellent method of presenting and teaching the information from the CD's. My kids liked it for awhile.
However, I have found for grades 4 - 7 (at least) that it falls a year behind of Saxon and other reliable homeschool math curriculum, and is not very challenging. My kids became bored about half-way through the book. If your child must take a standardized test under your state's homeschool law, he/she may have trouble with the math portion.
My daughter used to hide when it was time for math! Now she *asks* to do it. She loves seeing her progress, as do I. This curriculum is great! If you want to see a demo, the company has a website with a great demo feature for each grade level. I just can't enough good about it! Be sure to have your child take the placement test before selecting a grade level. BTW, I am a homeschooling mom of three and have been schooling since 1998. We have also done Algebra 2 by Teaching Textbooks and my eldest says that now she REALLY understands math. You can't get a better recommendation than that.
