About Roman Numerals
Letters like X, V and I stand for numbers here. Your child reads a Roman numeral and taps the number it means, or does the opposite and picks the numerals for a number. Tricky pairs like IV and IX show that a smaller letter in front takes away.
How to play
- Add up the letters: I is 1, V is 5 and X is 10.
- Take away a small letter in front of a bigger one, then tap the answer.
- With a keyboard, the number keys choose an answer, 1 for the first one.
What your child practices
- Reading Roman numerals
- Writing numbers the Roman way
- Adding and taking away values
- Careful reading
