Teacher Notes (not visible to students)

This activity helps students practice finding factors, recognizing factor pairs, and distinguishing prime vs. composite numbers. Use the pages in order: review recap, vocabulary, interactive prompts, practice matching and sorting, then assessment and partner work. For the partner activity, have simple materials: paper, pencil, and counters or small objects for modeling. For open-ended responses, high-quality answers will show clear reasoning: list of factor pairs or show dividing calculations, correct identification of factors, and an explanation of why each number is a factor (e.g., 6 × 3 = 18 so 3 is a factor of 18). Teachers can mark answers correct when the student lists all factors or gives a correct explanation for their thinking.
