Ancient Incan Quipu Knotted-Cord Record Keeping

40 mins Ages 7-12 Anywhere

An engaging, screen-free learning activity that builds real-world creativity and critical thinking for kids aged 7 to 12.

Materials Needed

  • • Thick cotton cord or clothesline (main cord) (50 cm)
  • • Colored yarn or embroidery floss (red, blue, yellow, green) (4 strands)
  • • Printed Incan quipu knot chart guide (1 sheet)
  • • Scissors (1 pair)

Pro Tips

  • → The Inca Empire managed taxes, population, and food storage across thousands of miles using knotted string quipus instead of writing.
  • → Tie four colored pendant cords along one main horizontal cord: each string represents a different category (e.g., green = corn, red = sheep).
  • → Tie single knots at the top for hundreds, middle for tens, and figure-eight knots at the bottom for units.

Safety First

None; clean yarn and scissors activity.
