They are a list of 220 words that are used so often in print that together they make up an estimated 75% of all words used in books. Some of the words cannot be decoded using conventional strategies so memorising them until they are known by sight is beneficial.

常用字是指一些在英文常用的220個字詞，大概佔英文書中75%的用字量。有些常用字不能用一般拼讀解碼方法記憶，因此孩子如果能直接記憶這些例外字詞，會有利閱讀。

High Frequency Words are sometimes referred to as Sight Words. Sight words are defined by our students. Their sight words are the words that they can already recognise by sight without using any specific strategies. The more sight words our students recognise, the easier reading will become for them.

High Frequency Words 有時指 Sight Words (常見字)。在學生層面，Sight Words是學生不需要用任何拼讀解碼方法，透過視覺便能辨認的字詞。學生記得愈多常見字，對提升閱讀流暢度愈有幫助。

Many of the words defy standard phonetic conventions, meaning they are impossible to sound out. They are often also difficult to illustrate, so children can't use illustrations in picture books to make a deeper connection to these words. Can you illustrate "is" or "it?"

很多字詞違背標準拼音規律，很難發音。此外，一些字詞難於用圖像表示，因此，孩子不能用繪本的插圖與這些字詞建立聯繫，例如 'is' 和 'it'。

The wonderful thing about these words being so common is that children learn them easily with repetition because they are usually words that they already have in their everyday vocabulary.

Working hard to learn these words by sight (memorising) pays off. It allows students to free up cognitive resources so they can focus on the tougher words that require strong decoding skills.

這些字詞常見是因為我們日常生活中經常使用這些字詞，而孩子能透過不斷重複去掌握。

如能透過記憶學會這些常見字，可讓孩子騰出更多認知空間，以集中學習需要高拼讀解碼技巧的較深字詞。

Repetition is the key to success in learning HFW and turning them into sight words that our students can recognise and read quickly. A selection of apps and online games are highlighted on this website to help students learn HFW.

Below are some activities and games you can try with your child at home off-screen. Use HFW words from the list above.

重複是學習常用字的關鍵，孩子如能夠將常用字轉化為常見字，閱讀速度將有所提升。孩子可在此網站找到一些應用程式和網上遊戲學習常用字。

家長可與孩子在家利用以下活動和遊戲，訓練孩子學習常用字。常用字可參考上方的字詞表。

Write sight words on index cards, and hide them around the house. Set the timer and give your child two minutes to find as many sight words as she can. At the end of the two minutes, have her read the list to you. She gets one point for every correct word. Repeat, challenging her to break her own record.

首先，將常用字寫在小卡片或紙張上。然後，將字卡藏在家中任何角落。孩子需在2分鐘找出字卡，愈多愈好。最後，著孩子讀出找到的字卡上的常用字。孩子可不斷嘗試，挑戰自己。

Using small cards, write out pairs of sight words and place them facedown on a table. Take turns flipping over the cards and reading the words. If you make a match, you keep the cards. The person with the most cards when they are all turned over wins.

配對記憶遊戲 - 為若干數量的常用字製作字卡，每個字兩張。然後，有字的一面向下，再調亂所有字卡的位置。接著，輪流翻開字卡並讀出字詞，如能翻開相同的字卡，就自己保管。最後，擁有最多字卡的人便勝出這遊戲。
