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.
Cut out the gray key silhouettes. Cut out each of the keys
(yes, it’s a pain, but TOTALLY worth it). Take the keys to an office/copy shop
to be laminated. Use thick lamination sheets and space the keys widely. Once laminated, line up
the keys with each corresponding silhouette, using them as a guide
for where to cut the lamination so the final result is a rectangle shape
with the key floating inside it.
Put the silhouettes (or locks) inside the thirteen
trading-card sleeves. Add addition problems to the keys with a fine-tip
dry-erase marker. On the back of each key’s corresponding lock, write the
answer on the sleeve with the marker.
Before my son played the Lock-and-Key Math game, we read
Loreen Leedy’s Mission Addition. (I
love Leedy’s books.) Because the book explains how to add numbers when they are
stacked vertically (as opposed to 3 + 4 =), all the Lock-and-Key problems
were written that way.
It’s time to play!
I put all the keys is a jumbled pile on the table and laid
the locks face-down so the answers were visible. One by one my son picked a
key, solved the addition problem, and found the sleeve with the answer. Then he
flipped over the sleeve and slid the key into the lock. If he was right, the silhouette
matched the key perfectly.
My son patiently and quietly worked through all 13 problems,
matching each key to its respective lock. While I planned for him to play the
game independently, I failed to consider how excited he’d be with each correct
