This is a PPT lesson designed to get students used to the correct tongue placement to say voiced and unvoiced TH sounds. First Ss are asked to place a finger in front of their lips and they must feel their tongue touch (lick) their finger. Once they've got used to that, the teacher will give each student a lollipop that s/he will hold in front of their lips. With each TH word they say, they'll be able to taste the sweetness of the candy and the tongue placement will have a positive association for them. I used two supplementary YouTube videos of voiced and unvoiced TH words made by The Accent's Way. The students repeated the words with the lollipops. It has been a great success each time I've taught this!
