   • Scissors: Used for cutting thin materials like paper or thin metal sheets.
2. Measuring Tools 📏
   • Ruler: Used to measure lengths and make straight lines.
   • Tape Measure: Used to measure longer distances.
   • Protractor: Used to measure angles.
3. Joining Tools 🔧
   • Hammer: Used to drive nails into wood.
   • Screwdriver: Used to drive screws into wood or metal.
   • Glue: Used to stick pieces of wood or metal together.
4. Shaping Tools 🛠️
   • File: Used to smooth rough edges of wood or metal.
   • Sandpaper: Used to make wood or metal surfaces smooth.
   • Pliers: Used to bend or hold metal parts.

Methods of Shape Construction

1. Folding 📄
   • Paper Folding: Making shapes like planes or boats by folding paper.
   • Metal Folding: Bending thin metal sheets to make boxes or containers.
2. Bending 🔄
   • Wood Bending: Using steam to make wood soft, then bending it to make things like chair backs.
   • Metal Bending: Using tools to bend metal rods into shapes like rings or hooks.

Examples

• Folding Paper to Make a Paper Plane ✈️
  1. Fold the paper in half.
  2. Fold the top corners to the center.
  3. Fold the wings down.
• Bending a Metal Rod to Make a Hook 🔩
  1. Heat the metal rod if necessary.
  2. Use pliers to bend the rod into a hook shape.

Remember, always be careful when using tools. Safety first! 🚧
