This is the FIRST time my daughter understood what ones, tens, hundreds meant!
To play this game, you need two boards (laminated paper) labelled as you see in the picture, preferably NOT the same color as your blocks. You also need base ten blocks and three dice.
It's usually played as "Race to 100", but I found that we didn't get enough practice making change for that to help. We race to three hundred, hence the third die. With one die, we'd be there all day.
The first player rolls the dice, calculates how many one blocks to pick up, and then makes any necessary exchanges if he has too many blocks in a column. Play continues until someone reaches 200. We played this every day for a week. She still couldn't "carry" on paper, but at least she got the place value idea. And kicked my tail at this game, lots.
Variation: When we started learning borrowing, we played this game BACKWARDS. Start with three hundred and race to zero.
