1. Say the numbers 1-20 in Mandarin
2. Read the Chinese characters of 1-20
3. Write the Chinese characters of 1-20
Learning the Chinese characters of 1-20 is not too difficult. As you may have discovered, the number 11 in Chinese characters is 10 plus 1 , as十一 shí yī (eleven). Following this rule, the other numbers are all combinations of two Chinese characters.
In details, the numbers 1-20 are:
一 yī (One)
二 èr (Two)
三 sān (Three)
四 sì (four)
五 wǔ (five)
六 liù (Six)
七 qī (Seven)
八 bā (Eight)
九 jiǔ (Nine)
十 shí (ten)
十一 shí yī (eleven)
十二 shí èr (twelve)
十三 shí sān(thirteen)
十四 shí sì (fourteen)
十五 shí wǔ (fifteen)
十六 shí liù (sixteen)
十七 shí qī (seventeen)
十八 shí bā (eighteen)
十九 shí jiǔ (nineteen)
二十 èr shí (twenty)
I have made a set of cards on Quizlet (quizlet.com or download the app for phone or ipad) to help your child practice learning the numbers.
Search for laoshilinda (all one word lower case) and then choose numbers 1-20.

You do not need to know any Mandarin yourself to use any of these resources.
