re: unlearning.

You know, I have a similar experience with DD. When she was 4 she could do simple sums in her head. But last year (5 yr old) she insisted that she needed the abacus, like in the school, and you could see trying to do the sum in her head while at the same time counting with the abacus like she was told in the school. She got mad at me because I told her not to use the abacus frown

In general, I think she has lost completely her self-confidence and thinks everything is so difficult.
