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
Danielle has 18 marbles. All the marbles are either black or gold. There are 4 more gold marbles than black. How many black marbles are there.
