4th grade measuring angles worksheets
Measuring angles worksheets for fourth grade print each angle over its own protractor scale: ticks every 10 degrees, labels every 30. One ray rests on 0, every answer is a ten-degree multiple, and reading the scale carefully is the whole game.

Every version prints on US Letter or A4, with its answer key on the last page.
How to teach this
Start every problem with the same question: which ray is on 0? Then count up by tens along the ticks, touching each one, until the second ray. When 70 turns into 110, that is the classic wrong-end read. Have your child say whether the angle looks smaller or bigger than a square corner first, then check the answer against that estimate. The estimate-first habit catches nearly every scale mistake.
Watch for: Kids read from the wrong end of the scale and turn 70° into 110°. Start counting from the ray that sits on 0. Kids count the big marks as tens without checking. Each small tick is 10 degrees, and each labeled mark is 30.
Common questions about measuring angles
- Does my child need a real protractor for these sheets?
- No. The protractor scale is printed around every angle, so all the practice lands on reading it correctly. That is the hard part of measuring angles anyway, and it transfers straight to the plastic tool.
- Why are all the answers multiples of ten?
- Every measure from 20° to 160° lands exactly on a tick, so a wrong answer means a misread scale, not a shaky eye. Reading from the wrong end shows up instantly: 70° and 110° are different ticks.
