Children love to color. It is an almost universal love, although there are a few who would prefer to do something else. Coloring can be a great tool in the Sunday School classroom. Instead of viewing it as a time filler, which it can be as well, learn to use it to your advantage.
Some students will be too wiggly to listen to an entire lesson. If you are teaching very young children, consider giving them a coloring sheet to work on while you teach. This will keep them quiet, and it is an ideal situation for a multi-age classroom. The older children can listen without interference, and the younger children will still be learning.
Choose coloring sheets that match your story. Then, talk to the children about the picture as they color. Have them review the story using the picture.
Coloring sheets also help the children recap the lesson for their parents. When they take the picture home, the parents are likely to ask them about what they learned. This will reinforce the lesson.
You can find free coloring sheets easily online. Try Kids Sunday School or DLTK Sunday School to get free pages you can print and copy for your class.
