Geometry Study of Angles Lessons Album and Nomenclature Material Unit 7 BUNDLE

This bundle of resources includes lessons, instructions, and printable materials for the following presentations for the study of angles:

These presentations are used:

• To measure the amplitude of an angle in degrees.
• To identify and define a whole angle, a straight line, a right angle, an acute angle, and an obtuse angle.
• To identify and name the parts of the angle.
• To introduce the measurement of angles using an instrument rather than purely sensorially.
• To measure and construct angles using a protractor.
• To construct and differentiate between oblique and perpendicular lines.
• To construct and differentiate between a ray and a line segment.
• To identify relationships between two angles.
• To explore relationships between angles of the same kind.
  

This resource includes:

• Montessori Protractor Materials Analysis
