# 4.GSR.7: Angles and Angle Measurement

Investigate the concepts of angles and angle measurement to estimate and measure angles.

- Subject: Mathematics
- Appears in: Grade 4, https://georgiahomeroom.org/standards/math/grade-4.md

## Expectations

- **4.GSR.7.1**: Recognize angles as geometric shapes formed when two rays share a common endpoint. Draw right, acute, and obtuse angles based on the relationship of the angle measure to 90 degrees.
- **4.GSR.7.2**: Measure angles in reference to a circle with the center at the common endpoint of two rays. Determine an angle’s measure in relation to the 360 degrees in a circle through division or as a missing factor problem.

## Georgia Milestones coverage

- Mathematics Grade 4 (EOG). Geometric & Spatial Reasoning. Investigate the concepts of angles and angle measurement to estimate and measure angles. (about 10% of the test; 6 points)

## What mastery looks like

Georgia's Achievement Level Descriptors. The levels are cumulative: each includes the ones before it. Proficient is on grade level.

- **Beginning**: Identify an angle at the center of a circle as right, acute, or obtuse.
- **Developing**: Given an angle or an angle measure, identify the angle as right, acute, or obtuse. Represent and identify angle measures using degrees.
- **Proficient**: Given a circle divided into equal-sized wedges, find the angle of a wedge by dividing 360 by the number of wedges.
- **Distinguished**: Investigate the concepts of angle measure using degrees to solve real-life mathematical problems.

## The same standard across grades

- Grade 2, 2.GSR.7: Draw and partition shapes and other objects with specific attributes, and conduct observations of everyday items and structures to identify how shapes exist in the world. https://georgiahomeroom.org/standards/code/2.GSR.7.md
- Grade 3, 3.GSR.7: Identify area as a measurable attribute of rectangles and determine the area of a rectangle presented in real-life, mathematical problems. https://georgiahomeroom.org/standards/code/3.GSR.7.md
- **Grade 4, 4.GSR.7 (this standard)**: Investigate the concepts of angles and angle measurement to estimate and measure angles.
