I have come across a recent study on the treatment and diagnosis of ADHD children in Taiwan. The study was published in the Journal of Pediatrics and titled “Influence of Relative Age on Diagnosis and Treatment of Attention-Deficit Hyperactivity Disorder in Taiwanese Children”.
孩子們要如何學習單數、複數和數數字?最好的方法當然是用實物來練習囉!拿出一把鉛筆，帶著孩子們數著鉛筆，順便練習在什麼情況下用單數，什麼情況下用複數，例如，I have a pencil. I have two pencils. I have three pencials.
當孩子孰悉如何用單複數後，可以漸漸地加入其他的物品來練習and的用法喔! 例如，I have a pencil and two markers. I have two pencils and three erasers. I have three pencils, four flowers, and five pens.
再來，就可以加上如何問問句啦！例如：What do you have? I have ___, ___, and ___.
