We are one week into our school year with Teaching Textbooks 4 and LOVING IT. I had read raving reviews and thought it would be a great program for my 10-year-old; now after using it a week, I could not be happier with my decision. We decided to bite the bullet and buy new since I worried about the quality of used discs I would find elsewhere. No glitches yet that I can see but lots of little extras that make my son's learning experience so much more fun. I think he is a week ahead in lessons already because he just wants to keep going every day! Hooray for banishing the math tears!
Though it is a bit pricier than other options, it is so worth it. I have three boys, and so far I have used this on my older two (my youngest will start in a year). Neither of my boys loves math, and this is pretty effective at engaging and teaching them. I do think it is a little below grade level, but that's fine with me and they will just go at their own pace. I believe it would be considered the spiral method which is great at keeping them from getting bored of doing too many of the same type problems in a row. I know that doesn't work for every kid, but so far I love Teaching Textbooks! It also frees me up to do one-on-one with my kids and teach subjects that I like better.
I love Teaching Textbooks! Math was so frustrating for me to teach, I am so thankful to have this program. Some people find it expensive...the program itself, I find very reasonable. I can continue to use it with future children. Though, I think the workbooks are a bit pricey. I think it is slightly below grade level, although that works well for our family. There are not a lot of drills, which I wish they would add for struggling students. If your student is excellent in Math, you may need to buy a grade or two ahead. Aside from the lack of drilling, I am VERY HAPPY with Teaching Textbooks 4.
