What students practice
Start with two rays and their shared endpoint, classify angles against a known right angle, and draw on dot grids. Then share a circle into equal wedges, count wedges and unit angles, estimate and read printed 360-degree protractors, and use a classroom protractor. Angle stories, Angle Code, and Mixed Review complete the sequence.

What's inside
- p. 3
Two Rays, One Endpoint
Decide which figures are angles, then find each vertex.
- p. 4
Right, Acute, or Obtuse
Compare each angle with the known right angle, then circle its name.
- p. 5
Draw Angles
Draw a second ray from the dot to make each angle, then answer the questions.
- p. 6
Wedges of a Circle
Find the measure of one wedge by completing each number sentence.
- p. 7
Count the Wedges
Count the wedges inside each angle, then write its measure with the degree symbol.
- p. 8
Unit Angles
Count the unit angles that fit, then write the measure with the degree symbol.
- p. 9
Read the 360 Protractor
Estimate, then read the protractor, writing the measure with the degree symbol.
- p. 10
Measure on the Protractor
Read the protractor, check each reading, then write it with the degree symbol.
- p. 11
Use Your Own Protractor
Use your protractor, write each measure with the degree symbol, then circle its name.
- p. 12
Angle Stories
Read each story, show your thinking, then write the measure with the degree symbol.
- p. 13
Angle Code
Answer each question, writing measures with the degree symbol, then spell the word.
- p. 14
Mixed Review
Solve each problem, writing angle measures with the degree symbol.
Georgia standards covered
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.
In this packet: pages 3 to 5, 11, 13, and 14. 4.GSR.7.1 practice in all our packets
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.

Who it's for
Grade 4 lessons on classifying and measuring angles. Wedges and unit angles come before protractors. Angle measures use multiples of 5 from 10 to 170 degrees. Students write the degree symbol in measure boxes; the own-protractor key accepts 5 degrees either way. The 26-page packet includes 12 practice pages, 12 matching keys, a cover, and a teacher page.
