A Year 4 sheet for reading Roman numerals up to 100, over three pages. A worked example breaks LXVIII into L, X, V and III to reach 68. Pupils then convert sixteen numerals, from XIII and XXIV to XCVI and XCVIII. Page 2 asks them to put XL, XIX, LX, XC and LXX in order from smallest to largest, then to write < or > between XLV and LXV, and between XCII and LXXXIX. The key shows every answer. It follows England National Curriculum number and place value.
Number - number and place value
“read Roman numerals to 100 (I to C) and know that over time, the numeral system changed to include the concept of zero and place value”
All sixteen items on page 1 ask pupils to read a numeral from XIII to XCVIII and give its value.
LXVIII = L + X + V + III = 50 + 10 + 5 + 3 = 68, with a guide to I, V, X, L and C.
Sixteen numerals in boxes, such as XXIX, XLVIII, LIX, LXXXII and XCVIII, to write as numbers.
A row of five numerals to write from smallest to largest, then two comparisons to complete with < or >.
The sixteen numbers, the order with each value shown, and both comparisons.
Partition first
Ask pupils to underline each letter group before adding, as in the worked example. Do number 1 together.
Spot the subtractive pairs
Point out XLII, XLVIII, LIX and XCIII, where a smaller letter comes before a larger one, and ask pupils to circle that pair first.
Plenary
Use the ordering task at the end of the lesson. A pupil who writes XIX after XL has compared the letters, not the values.
