GREAT FOR INDIVIDUAL OR WHOLE GROUP INSTRUCTION! THIS UNIT HAS RIGOROUS CORE INSTRUCTION AND ASSESSMENTS.GREAT FOR DISTANCE LEARNING, TOO, WITH EASY TO USE PACKETS, ACTIVITIES, AND ASSESSMENTS NEEDING LITTLE INSTRUCTION. • Also, here are a few comments from teachers who are honestly complete strangers to me who have used very similar book units I have created: "I just purchased this product, and so far I'm very happy with what I've seen."
