Five pages on Roman numerals, from Year 4 numerals to 100 up to Year 5 numerals to 1,000 and years. Page 1 starts with a key of the seven letters and the six subtracting pairs, then changes numbers to 100 both ways. Page 2 breaks numerals to 1,000 into hundreds, tens and ones (CDXLVII = 400 + 40 + 7 = 447), then reads numerals with no tens or no ones. Page 3 writes numbers to 1,000 as Roman numerals, with a worked example step by step. Page 4 reads years on foundation stones, a clock tower and the end of films, then writes years in Roman numerals. Page 5 finds the mistakes (49 is XLIX, not IL), compares numerals with <, > and =, and puts numerals in order.
Write the seven letters on the board with their values and ask what happens when a smaller letter comes before a larger one. Build 447 together a place at a time: 400 is CD, 40 is XL, 7 is VII. Page 5 is a good one to talk through: why is 49 written XLIX and not IL?
Look for Roman numerals together: on clock faces, foundation stones, the end of film credits, the chapters of a book or a monarch's name. Ask your child to read the number, or to write the year they were born in Roman numerals.
