Tell me if this sounds familiar.
Your child brings home a page of a page of double-digit subtraction problems.
You know… the kind where you have to “borrow” from the tens place to do the operation in the ones place.
You got this, you think…
But no, your kid politely informs you. You aren’t supposed to borrow. Instead, your child needs to use a method where he “counts up” from the number.
What in the world? This isn’t subtraction…at least not the way you learned it.
How are you expected to help your kid when the method doesn’t even make sense?
