DD6 has been using it to perfect her place value to millions by playing a game - she would make a number for me to guess and if I guessed right it was then my turn to make a number for her to guess.
DD8 has been using it for long multiplication and as a precursor to two digit multipliers.

We have an abacus . . . but I haven't used it much. You've inspired me to bring it out! Thanks for linking up!
We use our abacus with the Right Start Math program I use with my son. It is a great math manipulative and it helps teach the trading/borrowing with subtracting in a way that makes sense. Thanks for sharing on NOBH!
