Blend printed letters to read the words it and in, and blend a beginning sound onto ip to build new words.
Short a built cat, sat, and mat. Now short i builds its own words. Blend i with t: it. Blend i with n: in. You already know both sounds.
Ip is a small ending you will see again and again. Add r to the front: rip. Add z to the front: zip. One new beginning sound, one new word, just like cat and sat.
Mastery looks like: They blend it, in, rip, and zip correctly, connecting short i words to the same blending skill used for short a words.
Common stumbles: Reverting to the short a sound out of habit instead of the short i sound; forgetting the ending sound when reading a new ip word.
