8 questions with a Dinosaurs theme plus a full answer key. Perfect for Grade 4 Math.
⬇ Download WorksheetStudents will measure, classify, and add or subtract angles using dinosaur-themed real-world scenarios.
Before Q6, have students use a protractor to draw the two angles from the meteor crater question on paper — measuring 115° and 65° themselves before checking the addition. This grounds the abstract sum in physical experience.
- Maya finds a fossil bone on the ground. The bone makes a straight angle. A straight angle measures 180°. Is this angle bigger or smaller than a right angle of 90°? Write bigger or smaller, then write the difference in degrees.
- Maya spots a dino egg resting against a rock. The crack on the egg points at an angle of 45°. Is this angle acute, right, or obtuse? An acute angle is less than 90°. True or false: 45° is an acute angle.
- Maya measures the tip of an ancient fern leaf. One side points at 0°. The other side points at 130°. What type of angle is 130°? Then Maya bends the leaf to 50°. What type is 50°? Name both types.

About this Math worksheet for Grade 4
In fourth grade, students transition from informal angle comparisons to precise measurement using protractors and understanding angle composition, which this worksheet reinforces through multiple problem types aligned with CCSS 4.MD.C.5-7. Teachers can use these problems to assess whether students can identify angles, measure them accurately, and decompose angles into smaller parts—foundational skills for geometry and later trigonometry.
This printable Math worksheet is designed for Grade 4 students and covers Angles. The Dinosaurs 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.
