Re: 新思惟速算、手指快算???
| my daughter has joined their summer course for "+". at the first lesson, she did not know how to calculate even 1 question (all questions are: xxx + xxx + xxx = ???). after she finished the course, now she can finish 20 questions around 5-1/2 min and all correct. sometimes, she spended 6-1/2 min and 1 answer is incorrect. i'm so satisfy her result and i prepare to let her study "-" course in september. |
