Now the child is in grade one and will soon be in grade two. He took a math thinking class in Moby for three months. The teacher speaks very well, but the children don't like it. So later, after the class, I changed the head for the child. Although there are also a few small basin friends, the number is half less than Moby's. Anyway, my children are more suitable for this small class, and the chief has a better effect.
