Grades 3, 4, 5 and 6 students will solve both single and multiple step story problems using all 4 operations. Each story problem is introduced without numbers to increase students understanding of what the story is asking and representing. This lesson is designed to provide authentic application to all 4 operations and previously learned skills including: addition and subtraction in the thousands (with regrouping), multiplication (single and 2x2), division (with remainders) and fractions/ decimals. Students will apply multiple problem solving strategies, including base 10 blocks, picture models, number lines and traditional algorithms are use to drive instruction and encourage participation and collaboration. Lesson rigor and complexity increases as students are challenged through a series of questions all including models, scaffold and interactive pauses. As students progress through examples the complexity and rigor increases. Scaffolds and animations provide direction and step-by-step procedures to increase visual understanding. The lesson is completely editable and includes 20 problems with multiple models, steps, scaffold and questions for each.
