Educational worksheet for children to identify and categorize everyday items by material type, promoting recycling awareness.

Problem Overview:

The task involves identifying objects made from recycled materials and categorizing them into the correct material groups: Plastic, Paper, Metal, and Rubber. For objects that do not belong to any of these categories, an "X" should be marked on them.
