How have the rest of you taught your young mathematicians to WRITE THINGS DOWN? DS wants to do everything in his head (and is pretty darn good at it), but then he'll make silly errors that he wouldn't have made if he wasn't trying to play "human calculator"?

So if you have a young kiddo, who ENJOYS math - what's the best way to branch out into more "paper math"? We briefly did SM (before DB), but it was slow going (I probably started at the wrong level, and I didn't feel confident enough to just SKIP chunks, because it is DIFFERENT than how I learned math) and I stopped so as to not kill DS's enthusiasm for learning. Dreambox got us moving again. But he needs to learn to write things down!

Would BA make more sense for a mom enriching at home who grew up with "old school" math? If so, how do you figure out what level/where to start? Or would you suggest supplementing with another program?

I am LOVING hearing what others have tried/what has worked - THANKS! smile
