This resource focuses on teaching students how to solve addition and subtraction word problems through concrete, pictorial, and abstract representations. It begins with the goal of helping students understand how to use objects like connecting cubes or counters to model addition problems. The lesson features specific examples such as Maya's marbles and Sam's pencils, guiding students through creating visual models and writing corresponding number sentences. The resource also includes a section on subtraction, illustrating how to solve problems involving giving away items, like Leo's stickers, and comparing values, as seen with Mia and Tim's books. Emphasis is placed on self-assessment to encourage students to reflect on their understanding and skills.
