I think subtraction was hard for my emotional dd because she didn't like to take things away. But once she learned about borrowing, it became emotionally more satisfying to her. Sounds crazy I know.

It seemed to take FOREVER to convince her that the answer was the same whether you used rocks or flowers.
Too funny!!
What a sweety

Ds is ok with working sub/add. math facts via Yu-gi-oh.
4000-1800 is so much more worth working in his head than 3+6 (I kid you not, he didn't make it past 2's in math fact sheets last year). But yu-gi-oh math? No big deal. Still not a super speed demon, but fast enough not to keep the other kids waiting! (It has meaning for him, I am seeing that)
