Children can be like sponges and show great capabilities for learning several subjects in school and out. Many times children will learn best when they are "active learners". For example, if the child is studying history then a trip to a museum may help him to learn this subject more intensely and assist with recall. If fractions are being taught then cook with him! The two of you can practice fractions and other concepts of measurement by making a simple batch of cookies! Of course, there are opportunities in nature that can help to learn science concepts by taking hikes or sitting under the stars at night.
In essence, learning does not occur only within a classroom. Educational opportunities are all around us everyday. Our Education.com website is chocked full of ideas to help students of all ages learn and excel.
use a lot of reinforcement so that he begins to like it. tell him that wen he does say his homework he will get some icecream or something else he likes, maybe even an acitivty. this way he will start doing the homework looking forward to the reward.
As he starts doing his school work, etc. (whatever u reinforce him for), you can slowwwwwwwwwwwly fade away that reinforcement used for getting him to do this. this way while anticipating the reward, he develops a habit of doing school related work.
U should also make sure these things are MADE interesting for him, by using things he likes. for eg. if he likes toy cars, use them to teach concepts like addition or adjectives...etc etc... think of neway u can, to use his likes and strengths. but dont overdo it. :)
