Here is the URL which will take them to an interactive jigsaw puzzle of Roman numerals.
If you are not an expert on Roman numerals here is an explanation:
Symbol  Value 
I  1 
V  5 
X  10 
L  50 
C  100 
D  500 
M  1,000 
Numbers are formed by combining symbols together. So II is two ones, i.e. 2, and XIII is a ten and three ones, i.e. 13. There is no zero in this system, so 207, for example, is CCVII, using the symbols for two hundreds, a five and two ones. 1066 is MLXVI, one thousand, fifty and ten, a five and a one.
Symbols are placed from left to right in order of value, starting with the largest. However, in a few specific cases, to avoid four characters being repeated in succession (such as IIII or XXXX) these can be reduced using subtractive notation as follows:
