About this skill
Numbers to 20 use only I, V and X. It is the best place to practise the add-or-subtract rule.
How to teach it
- Make a quick reference strip with the seven letters.
- Look for places Roman numerals still appear: clocks, books, buildings.
- Break numbers into thousands, hundreds, tens and ones before converting.
Mistakes to watch for
- Writing IIII for 4 instead of IV (it appears on some clock faces but is not standard).
- Repeating a letter more than three times in a row.
