Actually, it's not difficult I think maybe you haven't found the right institution yet. I wonder if you have heard of neighborhood community education. My children, friends and children have been learning thinking mathematics there. Teachers use rich teaching AIDS and practical operations to lead children to know and understand mathematics in each class, which is in line with the thinking characteristics of preschool children. The math teaching AIDS here are children's favorite. It is good to cultivate mathematical thinking in play, which is in line with our educational philosophy for children. After class, children's logical ability has been greatly improved.
