How to teach this

Teach the flip strategy for new words: try the moon sound; if the word sounds wrong, flip to the book sound. Flexible decoding beats memorization, and oo is the perfect team to learn it on.

Watch for: The spelling gives few clues (oo before k usually says the book sound: look, took), so the ear decides. This sort cannot be done silently, and that is by design. The book sound hides in some of the most common words kids write: good, look, took. Misreading them with the moon sound is the error this sheet targets.
