My son (age 5) started PandaTree weekly lessons a few months ago. It took him a few lessons to truly warm up, but since then, I've noticed that he is speaking more Chinese, in complete sentences. I spoke some basic Chinese to him, so he did have a basic understanding of Chinese prior to starting with PandaTree, but he never would speak to me in Chinese until now. I'm very impressed. The tutors we've had have been energetic and high energy, and the lessons are fun and playful. I like how each lesson reviews prior knowledge as well, as the repetition helps him remember. I have recommended this program to several of my friends, and my son told me he wants to even learn Spanish!
