Personally, I think early education at home is useful. After all, after my children returned to their hometown, small steps of early education at home did have a very good effect. Teaching AIDS for small steps are open. My children can follow the course video every time they play, and they can also change the gameplay according to their own imagination. Take colored balloons as an example. Now they can not only count and classify, but also draw balloons of different shapes. I feel that the gameplay of these teaching AIDS is not rigid and can stimulate children's imagination.
