二 (èr) vs. 两 (liǎng) n 二 (èr) – ordinal number n Generally used in: n Counting (e. g. , 2, 12, 200) n A sequence of pure numbers (e. g. , phone number or address) n 两 (liǎng) – cardinal number n Generally used when it’s modifying something to indicate qty, e. g. in front of a measure word n 两个人 (liǎng gè rén) – 2 people n 两天 (liǎng tiān) – 2 days n Also certain pure numbers (e. g. , 2000, 20000)

11 -99 n 11 = “ 10” + “ 1” = 十一 (shí yī) n Same idea for 12 -19 n 20 = “ 2” x “ 10” = 二十 (èr shí) n 21 = “ 2” x “ 10” + “ 1” = 二十一 (èr shí yī) n Same for 22 -29 n Same for 30 to 99

Practice Exercise n Let’s all count from 1 -31

100 -1, 000, 000 n 100 = 一百 (yì bǎi) n 200 = 二百 / 两百 (èr bǎi or liǎng bǎi) n 101 = “ 100” + “ 1” = yì bǎi líng yī n 110 = “ 100” + “ 10” = yì bǎi èr shi n 1, 000 = 一千 (yì qiān) n 2, 000 = 两千 (liǎng qiān) n 10, 000 = 一万 (yí wàn) 20, 000 = 两万 (liǎng wàn) 100, 000 = 十万 (shí wàn) 1, 000 = 一百万 (yì bǎi wàn) 10, 000 = 一千万 (yì qiān wàn) 100, 000 = 一亿 (yí yì) 1, 000, 000 = 十亿 (shí yì) n n n

Tone Changes in “一” (yī) - the number 1 n 1. ) First tone (yī) n Counting from 1 -10 or as the last digit in a number sequence (e. g. 101) n 2. ) Second tone (yí) n When preceding a fourth tone, e. g. , 10, 000 = 一万 (yí wàn) n 3. ) Fourth tone (yì) n When preceding any other tone n 一百 (yì bǎi) n 一千 (yì qiān)

Counting large numbers n Start from the largest number “group” and end and the smallest n e. g. , Thousands to hundreds to tens to ones n Thousand = 千 (qiān) n Hundreds = 百 (bǎi) Tens = 十 (shí) Ones = “yī” to “shí” n n n 1, 111 = 1000 + 10 + 1 = 一千一百一十一 (yì qiān yì bǎi yī shí yī) n 2, 222 = 2000 + 20 + 2 = 两千两百二十二 (liǎng qiān liǎng bǎi èr shí èr)

Practice Exercise n 102 n 228 n 888 n 1234 n 2500

Practice Exercise n 102 = yì bǎi líng èr n 228 = èr bǎi èr shí bā n 888 = bā bǎi bā shí bā n 1234 = yì qiān èr bǎi sān shí sì n 2500 = liǎng qiān wǔ bǎi

Ordinals n It’s easy! n Just insert a “第” (“dì”) in front of the number n 第一 (dì yī) - first n 我第一次去中国 (wo di yi ci qu zhong guo) – I go to China for the first time n 第二 (dì èr ) – second n 第三 (dì sān) – third n…
