Overview

In this interactive activity, students will be led through steps to construct angles using a protractor. There are teaching activities as well as practice activities available. A handout that describes strategies taught during the interactive is available to be printed. After utilizing this resource, the students can complete the short quiz to assess their understanding.

Mathematics (2019) Grade(s): 4

MA19.4.24

Identify an angle as a geometric shape formed wherever two rays share a common endpoint.

Unpacked Content

UP:MA19.4.24

Vocabulary

  • Angle
  • Ray
  • Endpoint
  • Geometric shape
  • Vertex
  • Line
  • Point
  • Line segment

Knowledge

Students know:
  • Angles are geometric shapes formed when two rays share a common endpoint.
  • How to draw points, lines, line segments, and rays

Skills

Students are able to:
  • Identify an angle as two rays with a common endpoint.

Understanding

Students understand that:
  • angles are geometric shapes made of two rays that are infinite in length and are measured with reference to a circle with its center at the common endpoint of the rays.
Mathematics (2019) Grade(s): 4

MA19.4.25

Use a protractor to measure angles in whole-number degrees and sketch angles of specified measure.

Unpacked Content

UP:MA19.4.25

Vocabulary

  • Protractor
  • Angle
  • Whole number
  • Degree
  • Center
  • Circle
  • Intersect
  • Arc
  • Point
  • Ray
  • One-degree angle
  • Vertex

Knowledge

Students know:
  • Measurable attributes of geometric shapes, specifically angle size.
  • Units of measurement, specifically one-degree angle (degrees).
  • An angle is measured by the number or iterations of one-degree angles that exactly cover the rotation of the angle.

Skills

Students are able to:
  • Sketch angles given a specified measure.
  • Use appropriate tools to find angle measure.

Understanding

Students understand that:
  • the rotation of an angle is measured by the number of one-degree angles that exactly cover the rotation of the angle.
