My nine year old is on her third year of TT. She loves doing the lessons. She does very well with it. She's definitely learning and on grade level. For the most part I am very pleased. It saves me SO much time that she can do it independently. Learning math in an enjoyable and straightforward way is invaluable and TT definitely provides it, especially for kids that are struggling with or intimidated by math. I highly recommend it the program in general. My only little issue is, I really wish they would include or sell corresponding reinforcement activities for each lesson. I understand the program works by repeating and building on the material throughout the year and even throughout multiple levels to accomplish this. I just feel like it would be nice to have an extra activity or set of questions if there's a particular concept that needs extra practice. I've felt the need to create and assign drill sheets to reinforce things like memorization of the times tables.
