Aside from my obsession with new recipes and saving money, my whole goal in life is to trick my second-grader into thinking learning is fun. His teachers have mastered the art of deception. I … on the other hand … well, I’m working on it. Here’s the proof.
My son’s class is working on telling time. His homework
assignment one night was to find and count the number of clocks in our home. He
also had to draw one of them. Of course, he chose the clock with roman
numerals. This got me thinking. Maybe he’d enjoy learning about roman numerals.
And thus, this activity was born.
Our library had an amazing book that was both fun to read
and extremely helpful (I never learned roman numerals so I was totally clueless).
From David Adler’s book, I made a cheat sheet for my son translating
the values of each numeral.
I = 1
V = 5
X = 10
L = 50
C = 100
D = 500
M = 1,000
Then, I made a game board and playing cards. I laminated the board to use over and over with a dry-erase marker.

The game board has a reminder about three important rules:
When the same number is repeated one after the other, the
numbers are added.
When a larger number is followed by a smaller number, the
numbers are added.
When a smaller number is followed by a larger number, the
smaller number is subtracted from the larger.
Since my son is only in first grade, we did not use the “D”
(500) and “M” (1,000) cards I made; I’ll save those for when he’s ready to add
and subtract larger numbers. After reading the first half of Fun with Roman Numerals (the more you
read, the more complex the combination of numerals becomes), I placed three
cards on the game board and asked my son to write their values underneath with
a fine-tip dry-erase marker.
To start, I placed the cards in descending order by value so
no roman numeral was followed by one that had a higher value. Doing this meant that
the numbers would always be added. I gave my son a 1-100 numbers grid for help when
he needed it. Once he had the answer, he wrote it at the bottom of the game
board. We cleared the dry-erase marks on the board with a paper towel.
Gradually I added different cards, progressively making the
addition harder. Eventually, I placed a numeral with a higher value in the
middle or at the end, so my son would have some subtraction practice. This
tripped him up at first, but eventually he caught on and began thinking about
whether greater than/less than numerals should be added or subtracted.
Teaching a first-grader roman numerals was tough but my son
loved it. Now he can not only read our kitchen clock, but also will be able to tell
me what number Super Bowl it is this year!
