This resource focuses on the concept of addition through the part-part-whole model. The learning goals include understanding how to combine parts to find a whole, as well as discovering missing parts or wholes in addition problems. The document provides concrete examples using blocks and guided explorations with Cuisenaire rods to reinforce conceptual understanding. Students practice finding wholes and missing parts through various exercises, including drawing, pictorial representations, and writing equations. There are also sections for procedural fluency practice and problem-solving in real-life contexts, encouraging students to reflect on their learning and share their problem-solving processes.
