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.
