Th digraph

 We have learned two ways to pronounce th - a soft th as in moth and a harder th as in this. Our tongue needs to be out to say these sounds!

When reading, we have to try both ways to hear which sounds right. You will see this digraph in their reading books.

th as in moth  (make a moth as you say th)

th as in this (stroke your face with a feather as you say th)
