Week 10 - Final Carpentry Project: Build a Small Bench with Shelf
Objective:
Students will use a square tool (such as a speed square or combination square) to draw precise 90° lines—essential in almost all woodworking projects.
Materials Needed:
Pencil
Ruler or measuring tape
Speed square or combination square
Paper or small pieces of wood
Flat work surface
Instructions:
1. Start with a straight edge (the side of your paper or a wood scrap).
2. Place the square tool against the edge so one arm sits flush.
3. Use a pencil to draw a line along the other arm of the square—this creates a 90° angle.
4. Repeat at different points and on different surfaces to build confidence.
Skills Reinforced:
Understanding right angles
Tool positioning and handling
Accuracy in layout work
Preparing for real project cuts
✏️ Student Practice Area
Use this space to draw several 90° angles using your square tool.
