Mathematical Standards

4.MD.C
Geometric measurement: understand concepts of angle and measure angles. (4.MD.C.7)
4.G.A
Draw and identify lines and angles, and classify shapes by properties of their lines and angles. (4.G.A.1, 4.G.A.2)

Standards for Mathematical Practice

MP4.
Model with mathematics.
MP6.
Attend to precision.

Students are introduced to geometric concepts and vocabulary about lines and line segments. They use the terminology to talk about and solve problems.

Content in this Lesson

  • Identifying lines, line segments, rays, and points [E3].
  • Identifying and drawing parallel and perpendicular lines [E4].
  • Identifying angles created when lines intersect [E2, E4].
