“Wow! Mine the Gap for grades K-2 teachers really unpacks! Not only does the book provide dozens of great mathematical tasks, but—perhaps more importantly—it gives teachers the chance to consider each task; anticipate student responses—a critical first step in formative assessment; analyze actual student responses; and then consider what they would do in the classroom. Thoughts about modifying each task provide another option for each task. At a time when teachers are encouraged to regularly provide students with tasks that promote reasoning and problem solving, this book will help teachers dig deeper as they mine for understandings.”
