Overview

In this learning activity, students will watch a video to review right, acute, and obtuse angles.  Students will create various angles using strips of construction paper.  Finally, students will measure their newly created angles with a protractor.

This activity was created as a result of the Arts COS Resource Development Summit.

Phase

After/Explain/Elaborate
Mathematics (2019) Grade(s): 4

MA19.4.25

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

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.

AE17.VA.4.2

Collaboratively design and create artwork that has meaning and purpose.

UP:AE17.VA.4.2

Vocabulary

  • Constructed environment
  • Cultural traditions
  • Digital format
  • Engagement
  • Tertiary color
  • Preservation
  • Proportion
  • Principles of design
    • Unity
  • Shade
  • Style
  • Tints & shades

Essential Questions

EU: Artists and designers shape artistic investigations, following or breaking with traditions in pursuit of creative artmaking goals.
EQ: How does knowing the contexts, histories, and traditions of art forms help create works of art and design? Why do artists follow or break from established traditions? How do artists determine what resources and criteria are needed to formulate artistic investigations?

Skills Examples

  • Create a list of multiple ideas, sketches, or thumbnail-sketches before beginning the final version of an artwork.
  • Identify, select, and vary art materials, tools and processes to achieve desired results in their artwork.
  • Brainstorm (alone or with others) potential art styles for a given piece of art, such as Monet's Water Lilies.
  • Create an artwork from direct observation (still-life, self-portrait, figure drawing, etc.).
  • Design a two-dimensional drawings of a futuristic art room, town, or planet
  • Use wood, found objects, wire, paper, or clay-based materials to construct a three-dimensional form.
  • Locate business logos in the community and explore the visual arts skills and materials that were used to create these works.
  • Engage in group critiques of one's work and the work of others.
  • Experiment with art materials by using them in unusual and creative ways to express ideas and convey meaning.
  • Use and care for materials, tools, and equipment in a manner that prevents danger to oneself and others.
  • Mix equal parts of a primary and a secondary color located beside each other on the color wheel to create a tertiary color.
  • Use the design principles of repetition and alignment to add visual unity to an artwork.
  • Create a painting using a monochromatic color scheme by using one color (red) adding white to create a tint (a lighter value--pink) and adding black to the color (red) to create a shade (darker value).

Anchor Standards

Anchor Standard 1: Generate and conceptualize artistic ideas and work.

Learning Objectives

Students are able to:

  • Use a protractor to measure angles in whole number degrees,
  • Create and classify angles as a specified measure (right, obtuse, or acute).
  • Create artwork that has meaning.

Activity Details

This learning activity is best used after a lesson on right, obtuse, and acute angles.

Show the students the following video: Angles Song by NUMBEROCK  

After watching the video, review the 3 types of angles from the video with the students.  You can do this with an anchor chart or by writing their definitions on the board. 

Right Angle - measures 90 degrees

Acute Angle - measures less than 90 degrees

Obtuse Angle - measures 91 - 179 degrees

Distribute the materials:  (per student)

one black sheet of construction paper

one protractor

one silver sharpie or white paint pen

different colored pieces of construction paper cut into strips 1/2" wide x 3" long

glue

3 x 5 unlined index card (white)

pencil

Directions:  Students will create angles by gluing 2 strips of colored construction paper to the black sheet of construction paper.  Each type of angle should be represented by a different color.  Example: pink - right, yellow - obtuse, blue - acute.  Students should make a key for the color of angles associated with the type of angle on the white unlined index card and glue it on one of the corners of the black sheet for reference.  When students have created their angles using the strips of colored construction paper, they will measure their angles with the protractor and record the measurement on the black sheet under each angle using the sharpie or paint pen.

Assessment Strategies

Students will be assessed on the correct angle measurement of their angles as well as the type of angle they classify each angle.

Variation Tips

Students may complete this learning activity individually, with a partner, or in a small group (3 students).

Background / Preparation

The teacher will need a computer with internet connection and a projector to play the video.  The teacher will also need to make an anchor chart for the angle definitions or write them on the dry erase board. The teacher will need to precut different colored pieces of construction paper cut into strips 1/2" wide x 3" long.
