Fitting Activity is a term that can refer to a variety of activities, such as JIGSAW (6 letters), tryingon (8 letters), and jigsawpuzzle (12 letters). JIGSAW is an activity where pieces of a picture are cut into small shapes and then put back together to form the original image. Tryingon is an activity where people try on different clothes to see which ones fit them best. Finally, jigsawpuzzle is an activity where people put together a puzzle with many pieces to form a complete picture. All of these activities involve fitting pieces together in some way, hence the term Fitting Activity.
