Points, Lines, and Angles
In this unit students
• draw and identify points, lines, segments, rays, angles, perpendicular and parallel lines, triangles, and line symmetry;
• practice the four operations in length, area, and angle measure contexts.
Students develop their understanding of the concept of an angle and measure angles using protractors. They get additional practice with addition and subtraction in the context of angle measures, length, and area. Shapes are classified by their properties (lines and angles) and students are introduced to symmetry.
