Standard

Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.

Explanation

About the Math, Learning Targets, & Rigor

This standard asks students to draw two-dimensional geometric objects and to also identify them in two- dimensional figures. This is the first time that students are exposed to rays, angles, and perpendicular and parallel lines.

STUDENT SAMPLE RESPONSE

Performance Indicators: 4.G.1

Level 5: Exceeds Expectations

• Draws and identifies points, lines, line segments, rays, angles (right, obtuse and acute), perpendicular lines, parallel lines, lines of symmetry and right triangles, and use any of these to classify or describe two-dimensional figures.

Level 4: Meets Expectations

• Draws and identifies points, lines, line segments, rays, angles (right, obtuse and acute), perpendicular lines, parallel lines, lines of symmetry and right triangles, and use some of these to classify two-dimensional figures.
