🧭 The Three Workspaces in maths-net-tool

🔍 Mode 1: Explore Shapes

Pick from 15 shapes and nets. Use the slider to fold them in 3D. Overlapping faces in invalid nets turn bright red.

✏️ Mode 2: Draw a Net

Click squares on the 7×7 grid to place 6 squares. Click Test Fold to see if it makes a cube without collisions.

🧩 Mode 3: Shape Matcher

Use ‹ and › to choose a shape. Drag faces onto the workbench—they magnetically snap edge-to-edge. Click Clue for hints, then fold it in 3D!

🛠️ Helpful Exam Tools in maths-net-tool

🎯 Opposite Faces Quiz: Practice finding opposite faces without folding—a common Functional Skills question.
📊 Surface Area: Type in your measurements to see step-by-step surface area calculations.
🖨️ Print Net Templates: Create clean A4 worksheets (1 or 2 nets per page) with no black borders, ready to cut and fold.

📝 Four Key Exam Rules

Rule 1: Count the Faces — Cube has 6, Triangular Prism has 5, Square Pyramid has 5, Tetrahedron has 4.

Rule 2: No 2×2 Blocks — 4 squares forming a 2×2 square always collide and fail to make a cube.

Rule 3: Opposite Faces Never Touch — Opposite faces in 3D never share an edge on the flat net.

Rule 4: The 1-4-1 Pattern — A row of 4 with 1 on each side always folds into a valid cube or cuboid.
