A comprehensive lesson on calculating the area of irregular rectilinear shapes by decomposing them into smaller rectangles. Includes tiered practice, a project-based learning guide, and a detailed assessment rubric.

Students will learn to find the area of regular and irregular polygons by decomposing them into smaller rectangles, using a 'Shape Surgeon' approach.

A series of 3 hands-on centers focused on equivalent fractions using shapes, fraction strips, and number lines to build conceptual understanding.

A fast-paced, 35-minute secret agent-themed lesson where students master the connection between multiplication and division facts (1-10) using the 'I Do, We Do, You Do' model.

A mini-lesson designed to help students identify key information and break multi-step fraction word problems into manageable parts.

A comprehensive review session covering fraction equivalency, simplification, mixed number conversions, and basic operations with unlike denominators.

Students apply their fraction operations to solve multi-step word problems involving measurement and construction scenarios.

Focuses on adding and subtracting mixed numbers with like denominators, emphasizing the regrouping process and visual decomposition.

Focuses on the conceptual link between mixed numbers and improper fractions using visual models and the 'Multiply and Add' method.
