Lessons Unit 1, lesson 35
θ as in thin
One consonant, on its own page. Hear it, watch where it sits in each word's sheet, then say the words yourself.
θthe th in thin
Put the tip of your tongue gently between your teeth and blow air: th. No voice, just air. If it sounds like s or t, check that your tongue really touches your teeth.
Now say it yourself
Read each word from its sheet, out loud, three times. Where there's a play button, listen first and copy what you hear. Slow is fine — clear beats fast.
