Detailed plans for helping elementary students experience deep mathematical learning The more than 50 mathematical tasks in this guide will challenge your students to do deep problem-based learning. These ready-to-implement tasks connect concepts, skills, and practices and encourage students to reason, problem-solve, discuss, explore, justify, monitor their own thinking, and connect the mathematics they know to new situations. In other words, these tasks allow students to truly do mathematics! Written with a strengths-based lens, this guide includes: • Complete task-based lessons, referencing mathematics standards and practices, vocabulary, and materials • Downloadable planning tools, student resource pages, and thoughtful questions, and formative assessment prompts• Guidance on preparing, launching, facilitating, and reflecting on each task• Notes on access and equity, focusing on students’ strengths, productive struggle, and distance or alternative learning environments.
