# Cycle 159 ## 159.1 Letter Combinations #### Purpose and Procedure This task requires students to read words that contain the *oy* or *oi* letter combination without being asked to identify the letter combination or its sound before reading the word. ## 159.4 Patterns #### Purpose and Procedure This task asks students to read derivatives of -VC and -VCe base words that are NOT minimally different pairs. These derivatives have *-er* and *-est* suffixes. At this stage, students are still asked to read the underlined base word before reading the full derivative. ## 159.7 Word Parts #### Purpose and Procedure This task introduces the *-ful* and *-less* endings and their meanings. #### Important Reminders Remember to point to specific words when you say them, as directed in the instructor pane. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
