Creativity toys have both playful and educational attributes. Craft sets encourage children to use their imaginations, while often challenging them to follow directions and develop skills such as drawing or sewing. Model kits involve often complicated instructions but reward children for their diligence with a model to play with or proudly display. Construction sets, too, require time and patience but have limitless possibilities. Creativity toys have entertained children since the 19th century, when toy makers began mass-producing toys with educational features, introducing children to art, homemaking skills, and even engineering while they played.
