Grade 4
Overview
Each unit of the Teacher's Guide begins with a unit overview that provides a discussion of core mathematical ideas, explanation of the learning trajectory for the unit and for the topic (across units), identification of key points, and ways to support students having difficulties with the unit.
The Teacher's Guides include fullcolor images of each page of the student textbook with overlaid answers, mirrored by a teacher’s page with lesson notes. These provide specific pedagogical suggestions, including hatsumon (key questions or problems to pose to students), anticipated responses, strategies to support student thinking, and assessment perspectives.
Lesson plans are complemented by carefullycrafted instructional boards which guide students through the units. The Teacher's Guides place an emphasis on recognizing the student's experience, incorporating varied perspectives from student characters and encouraging young learners to make discoveries on their own.
Teacher's Guides are spiral bound books designed to lay flat, and include examples of blackboard organization that can be projected using classroom technology.
Sansu Math^{®} Teacher's Guide 4A is written for use with Sansu Math^{®} Grade 4 student textbook for units 17.
