Teach but listen to the children. Treat them with respect. Do unto others as you would have them do unto you. If a child is interested in a subject, delve deeper into it for a while. Cover it fully so it is learned all together, not just in chunks here and there.
Children love to be talked to about everything in detail.
They become more effective in communication skills, and seem to read better. They absorb more than you know by watching you everyday. If you want to teach them good things, you should be aware of what you do day by day. Explain directions step by step and make sure that they are understood before making the child try and do it themselves. Explore all different angles of explanation.
