Obelisk: Math Primer
Math Primer
This is the “ramp.” The goal is to teach enough math that diagrams and measurements become self-explanatory.
1) Counting
- Tally marks
- Grouping (suggest base‑10 or base‑12, but show both)
- Place value (a symbol for “ten”, “hundred”, etc.)
2) Measurement
- A unit of length
- A unit of time
- Area and volume as repeated measurement
3) Geometry
- Point, line, angle
- Triangle basics
- Right angle and the idea of perpendicular
4) Ratios & fractions
Teach ratio with pictures:
- half, third, quarter
- scaling diagrams up/down
5) Coordinates
- Draw a grid
- Label axes
- Show plotting points
Why this matters
Once a reader understands:
- how to count
- how to measure
- how to read a diagram
…you can encode almost anything that fits on a page.
