8 questions with a Mythology theme plus a full answer key. Perfect for Grade 4 Math.
⬇ Download WorksheetStudents will identify, measure, and calculate angles including right, acute, obtuse, and straight angles, and find unknown angles by adding or subtracting known angle measures.
Before Q6, pause and ask students to predict whether Maya's hidden treasure vault angle is acute or obtuse. This connects Q5's 35° and Q6's multi-step decomposition directly to the story, giving students a concrete reason to check their own answers.
- Maya enters the temple of Zeus. She spots a golden arrow — her special object — pinned to the stone wall. The arrow points at a right angle. How many degrees is a right angle?
- Maya picks up a unique item: a glowing shield of Athena. The shield has a corner angle of 45°. Is 45° an acute angle? Write TRUE or FALSE. An acute angle is less than 90°.
- Maya finds a rare find — a carved sun dial. One ray points at 0°. The other ray points at 110°. What type of angle is 110°? Write the type AND the measure.

About this Math worksheet for Grade 4
Fourth graders need to develop spatial reasoning and measurement fluency with angles to build toward geometry and trigonometry in later grades, making this practice with angle identification, comparison, and decomposition essential. Teachers can use these problems to assess whether students can distinguish between acute, right, and obtuse angles while applying the additive property of angles, then use results to differentiate instruction for students who struggle with angle composition versus those ready for more complex problems.
This printable Math worksheet is designed for Grade 4 students and covers Angles. The Mythology theme keeps kids engaged while they practice essential Math skills. Every worksheet includes a full answer key making it easy for parents and teachers to check work instantly. Aligned to Common Core State Standards (CCSS) for Grade 4 Math.
