Roman Numerals With Money Manipulatives

Roman Numerals
I (1) V (5) X (10) L (50) C (100) D (500) M (1000)

To help remember the order of the Roman Numeral Symbols, here are two pneumonics. We learned the first one.

In Venice, X-tra Little Children Drink Milkshakes.
In Venice, X-tra Lazy Cows Don't Moo.

To help understand the value of Roman Numerals, we labeled coins and dollars as follows:
I (1) = penny    
V (5) = nickel    
X (10) = dime   
L (50) = 50 cent piece     
C (100) = $1 bill   
D (500) = $5 bill             
M (1000) = $10 bill
Then as we read a roman numeral, we would lay out the coins that represented each numeral. Then the girls did a worksheet where there was a number written, and they had to write the Roman Numeral equivalent, using the money manipulatives to help them.
