Teacher's manual unit 1 for Grade 1 Reading Course.
This manual has all the essential material you need to teach the course. The first part of the book gives instructions for the phonics, and the second part for the reading.
I encourage you to read all the introductory material so you get the layout of the teacher's manual. It will save you time in the long run because you will know exactly where to go so you can find what you need.
