This book parallels the structure of the core Student Book in the Math 10 Common course. It provides support for struggling students from the start of each lesson, by reviewing prerequisite skills if needed, and offering a simpler presentation of the new content. Students can work through each lesson alongside their age peers and, if apporpriate, move to the Student Book to try questions in the mid-range difficulty levels. Thus, this resource can help students improve their mathematical skills and knowledge, as well as their habits of work, without the stigma of placement in a specialized program.
