Parents and caregivers should use the age ratings below as a general guideline, taking the abilities, temperament and interests of their children into account. Learning shapes and colors allows children to group or classify items -- children develop their ability to make logical connections -- a precursor to both math and language arts. If an aspect of a project is frustrating to the child, provide assistance - try to keep things fun. Sing songs, read stories or watch shows with a similar theme as the worksheet you choose to supplement the project - again focusing on extra activities that the child enjoys to help keep them motivated. Take breaks, when necessary.
