Math Game - Add & Subtract

I came up with a version of this apple game from Little Family Fun after I realized I didn't make enough apples for both of us to keep adding apples. 

Players:
2

What you need:

1 die
Game board (can be a plain sheet of paper, or a picture to match your theme)
Anything you can count (crumpled up paper, blocks, erasers, beads, pom poms, etc.)

Rules:
The first player roles the die and adds that many counters to the board.
The second player roles the die and takes that many off the board.
If there is not enough on the board to take away or enough off the board to add, then the player skips a turn. (C was always asking, "are there enough to take away?")
You can play as long as you want.

C loved this game!

We later played the game using star shaped erasers.
