Since you're in second grade, I suggest you draw a picture of 18 marbles. Color a few of them black and color a few of them gold.

Can you figure it out from here?
Here's a better way.

After you've drawn 18 marbles, color 4 of them gold. Then color half of the rest black and the other half gold.
7 black marbles
