They learn best with the approval of a caring adult who talks to them about what they are doing. Involve your children in finger plays and puppet shows. Interactive learning is better than dull repetitive learning. Any new imaginative way to get the information across is beneficial. Having children use math by counting everyday objects, measuring baking goods, etc. gives an effective basis for math.
Children learn more effectively when the parents are involved.
The need to know their parents support them in whatever they do helps them to excel. Not only reading about a subject, but also doing something in conjunction with and about the subject will be more beneficial as the child will have some hands on experience to help understand and remember about the subject. Teach but listen to the children. Treat them with respect. Do unto others as you would have them do unto you.
