Illustrative Mathematics Algebra 1 Unit 5 (formerly labeled “Intro to Exponential Functions” or “Functions” depending on the edition) includes teacher-only answer keys, assessments, and presentation materials. These detailed solutions—for each lesson’s tasks, practice problems, and activities—are accessible only if you sign in as a teacher on the Kendall Hunt (Illustrative Mathematics) website using a valid school or work email . The public student view does **not** include full answer keys; instead, students see only problem statements and are prompted to access answers through teacher support . In short, there’s no publicly available downloadable answer key—only the full key within the secured teacher portal.
