| 1 | Wood glue (water-resistant D3) |
| 1 | Wood paints or acrylic paints |
Also: sandpaper (grit 120 and 240), a utility knife or fine saw and, for joints, a rubber mallet.
Carving and finishing
- Clamp the workpiece flat on the spoilboard or secure it with double-sided tape, and set the origin as shown in the carving assistant.
- Engrave the fractions, cut the divisions with the 2 mm end mill, then cut out strips, frame and bottom. Secure the sheet with double-sided tape.
- Free the parts at the holding tabs with a utility knife or fine saw and sand the tab remains flush.
- Lightly break the edges with sandpaper (grit 120, then 240) and remove burrs.
Assembly and final touches
- Glue the frame onto the bottom. Paint each strip in its own colour so the denominators can be recognised even without reading.
- Tasks: how many quarters make a half? Which pieces add up to exactly one whole?
