UNDERSTAND THE IMAGE

24 = XXIV

XX is 20 and IV is 4. In IV, I comes before V, so subtract 1 from 5. Together, 20 + 4 = 24.

Try it in class

  • Cover 24 on the card and ask learners to read XXIV.
  • Explain the conversion: XX is 20 and IV is 4. In IV, I comes before V, so subtract 1 from 5. Together, 20 + 4 = 24.
  • Compare two number cards. Which represents the larger number, and how can you tell?
