A Year 4 conversion sheet for numbers up to 100 over three pages. A key box adds L = 50 and C = 100 to I, V and X, and a worked example splits 47 into 40 and 7 to make XLVII. Pupils then write sixteen numbers as numerals, from 23 and 35 to 89, 99 and 100. Page 2 asks for the longest numeral, the pupil's own age, today's day of the month, and 60 and 66. The key lists 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”
Page 1 asks pupils to write sixteen numbers as numerals up to C, including the subtractive forms XL, XLIX, XC and XCIX.
A key for I, V, X, L and C, and the worked example 47 = 40 + 7 = XL + VII = XLVII.
Sixteen numbers in boxes: 23, 35, 40, 44, 49, 50, 56, 64, 72, 78, 89, 90, 91, 95, 99 and 100.
Pupils pick out the longest numeral from their page 1 answers, write their age and today's date as numerals, then write 60 and 66.
All sixteen numerals, the longest one (LXXVIII, seven letters) and the answers for 60 and 66. Age and date answers vary, so the key shows the possible range.
