Keep the child interested in the chart by noticing things daily. Encourage him to start noticing kindness in himself so that he gets the idea that he is becoming a kind person. You don't have to reward him with candy but it could be something like a favorite meal, taking a walk in the park, going to a favorite place, having some friends over, seeing a special movie, going to the library, or being allowed to have a special privilege. You could even decide on these ahead of time and write them on slips of paper. The child can pick which one he wants but you have to be ready to do or allow whatever he picks to take place as soon as possible.
Children can then draw pictures of people, places, big and little things.
If they are too young to print, you could print the sentences they tell you about each page. When it is finished they can read it as often as they want. Each page could have a picture of one of the members of the family so that each member has their own page to work on. Later, you could put all the pages together and staple them. Written sentences can be included for each page.
