Inca records and a bridge
Topic What we know Quipus cords of cotton or llama-family fiber with knots; knots in a base-ten place system stored numbers; a quipu could have a few cords or several thousand Reading quipus the Inca kept careful census records on quipus, but knowledge of how to read most of them was lost Queshuachaca the last Inca rope bridge, of grass ropes over the Apurímac River; local people still renew it each June On a quipu cord, knots higher up stand for hundreds, then tens, then ones at the bottom; a gap with no knots means zero.
A quipu cord has 3 knots in the hundreds place, none in the tens and 5 in the ones. What number is it, Jun asks?
- 35
- 350
- 305
- 8
A cord has 2 knots in the hundreds, 4 in the tens and none in the ones. What number is it, Kira asks?
- 24
- 204
- 6
- 240
How would 470 look on a quipu cord, Luz asks?
- 47 knots in the ones
- 4 hundreds, 7 ones, a gap for tens
- 4 hundreds, 7 tens, a gap for ones
- 11 knots in a row
The Inca had no writing system. How did they keep census records, Milo asks?
- In books of paper
- On clay tablets
- They kept no records
- On quipus of knotted cords
Knowledge of how to read most quipus was lost. What does that mean for historians, Noah asks?
- Much of what they record can't yet be read
- There are no quipus left
- Quipus were books
- Each quipu can be read easily
Why might colors and the order of cords matter on a quipu, Pia asks?
- They stood for letters
- They showed the weather
- They sorted the information into groups
- They were just decoration
Two societies, same columns
Society Land and farming Building and engineering Records, writing and numbers Maya maize, beans, squashes and chili peppers in the tropical lowlands stone cities with tall buildings and carved monuments a writing system of word signs and syllables, now mostly deciphered; numbers in twenties with a shell for zero Inca potatoes, quinoa and maize, grown on terraces in the Andes roads of about 30,000 to 40,000 km and fine stonework, built without wheels or iron no writing system; quipus stored numbers in tens Using the same columns, how did Maya and Inca records differ, Ren asks?

- Both wrote books
- Both used quipus
- Maya writing; Inca quipus

Why would a grass rope bridge need renewing often, Bo asks?
- Bridges need no care
- Grass gets stronger each year
- Grass ropes wear out over time
- The river moves the bridge
