I have been using MUS with my nearly 10-year-old son for nearly 5 years now. We started in Kindergarten and he's now 1/2 way through Epsilon. We switched to Delta 1/2 way through Intermediate.
This has been one of the best curriculum choices I have made. You make it SO easy for me and for him! And, the new program is absolutely perfect.
Thank you so much for taking the time to create this curriculum. You have saved many people many hours.
I recommend Math·U·See over and over and over. And I explain in detail WHY it's the best.
