Level 5-3 focuses on the /oi/ sound written as either oi or oy. The general rule of thumb for deciding whether to use oi or oy in a word to make the /oi/ sound is straightforward: in the middle of a syllable, use oi; to close a syllable or end a word, use oy. Simply telling students that oy is used only at the end of a word is not enough, because a suffix can then be added to a root word ending in oy, so words like toys, joyful, and annoying still use oy rather than oi. You'll want to make this clear to your students.

The ten words in this level are as follows: boy, enjoy, toys, joy, point, join, oil, soil, coin, and choice. These, as usual, are high-frequency words that are important for students to know. With a little bit of oi vs. oy instruction, your students should find this level quite doable.
