Elementary Math: Angles
Unit Title: Elementary Math: Angles
This lesson was created by MeLinda Cromer with Nebraska ESUCC BlendEd Learning project. In this unit students will differentiate between different types of lines based upon their traits. Students will design various angles by connecting two rays together at a common endpoint. Students will also categorize angles as acute, obtuse, or right. Students will also identify angles found in their environment and justify them as acute, obtuse, or right.

Empower Learner Activity:
Detailed Description:
-Students will demonstrate current knowledge of lines and angles using a Google Doc to organize their thoughts.
-Students will then show and justify their results using a Flipgrid (show and explain their thinking)
-Students will use a scale of 1, 2, 3, 4 to self-assess their understanding of lines and angles using a Google Form (lines, line segments, rays, angles- acute, obtuse, and right)
-Students will set goals for the unit based on their learning targets and pre-assessment data
Knowledge Application:
Artifact Profile:
Google Slides Presentation: Geometric Concepts
Detailed Description:
Students will demonstrate their knowledge of lines (line segments, rays, and lines) and angles (right, acute, obtuse) by constructing a Google Slides presentation. Students will locate digital media that portrays these geometric concepts or create drawings using Google Drawing to create examples. Students will then analyze these pictures and categorize them according to the geometric examples they demonstrate. Students will share their presentations with peers where they will highlight and label each concept identified. Students will also generate definitions for line segments, rays, lines, right angles, acute angles, and obtuse angles on the Google Slides presentation.
