Reading the Tape Measure
Like Duolingo, but for Reading the Tape Measure. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.
A short one: 9 levels across 2 sections, about 18 minutes end to end, roughly 4 days at five minutes a day. It moves through Decoding the Blade and Real-World Measuring Moves. It starts from scratch.

Key ideas in Reading the Tape Measure
- Counting every individual mark mark-by-mark is slow and unnecessary
- Line heights on a tape measure indicate specific fraction sizes at a glance
- Taller lines represent larger fractional divisions like halves and quarters
- The half-inch line is the single tallest line between two whole-inch numbers
- It sits dead center between the two whole-inch marks
- Quarter-inch marks are the second-tallest lines between inches
- One quarter sits halfway to the half-inch line; three quarters sits halfway past it
- Each fraction tier steps down in line height
- Even fractions simplify into a larger fraction tier marked by a taller line
- 2/4 is read as 1/2 because it lands directly on the taller half-inch line
- Every unique mark on a standard tape represents an odd fraction (1/4, 3/4, 1/8, 3/8, etc.)
- Marks very close to the next inch are faster to subtract from that whole inch than counting up from the previous one
- One mark before 8 inches means 7 and 15/16 inches
- Counting up 15 individual ticks from 7 is slow and prone to miscounts
- Line height on a tape measure decreases systematically as fractions divide finer
- Eighths and sixteenths form the two shortest tiers of graduation marks

Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Reading the Tape Measure the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
