The workbook "Angles and Lines" continues practice to help students understand the different types of lines, such as straight lines, line segments, and rays. It explores angles, teaching students to recognize and name right angles and identifying acute and obtuse angles. This workbook presents a good opportunity to introduce students to using protractors to measure angles. Pages are included to engage students in identifying and drawing parallel and perpendicular lines.

In third grade, students should be introduced to the basic concepts of geometry, specifically focusing on angles and lines. They should learn how to identify and draw lines, such as parallel and perpendicular lines. Additionally, they should explore angles by recognizing and creating right, acute, and obtuse angles. This foundation helps them understand how angles and lines are part of shapes and real-world objects.
