This phrase likely refers to a specific resource tied to a learning activity. It suggests a section within a textbook or workbook (page 375) dedicated to the first lesson’s independent practice exercises, focusing on the topic of lines. The “answer key” component indicates the availability of solutions to those exercises, enabling students to self-assess their comprehension and application of the lesson’s concepts. An example would be a student completing geometric problems involving parallel and perpendicular lines, then checking their answers against the provided key.
The importance of this resource lies in its ability to foster autonomous learning. By providing a mechanism for students to verify their work, it encourages them to take ownership of their learning process. This method provides immediate feedback, reinforcing correct understanding and identifying areas needing further review. Historically, such answer keys were often found only in teacher editions, but their increased availability to students reflects a pedagogical shift toward self-directed learning and formative assessment.
