Measure the Radius & Diameter – 5 – In this worksheet, children will measure the radius and diameter.

Measure the Radius & Diameter – 5  – Engaging Geometry Practice for Kids!

Help young learners explore the world of circles with this fun and educational worksheet focused on measuring the radius and diameter! Perfect for upper elementary students, this hands-on activity introduces or reinforces the key geometric concepts of radius and diameter while developing critical thinking and measuring skills.

In this worksheet, children will practice identifying and measuring both the radius and diameter of a variety of circles. Using a ruler, students will measure the distance from the center of the circle to the edge (radius) and the distance across the entire circle (diameter). They’ll also apply their understanding of the relationship between radius and diameter, discovering that the diameter is always twice the radius.

This engaging resource is designed to:

• Reinforce geometry vocabulary (radius, diameter, center, circumference)

• Strengthen measurement and observation skills

• Support visual learning through clear diagrams

• Encourage independent practice and confidence in math

Whether used during math centers, independent practice, homework, or as a warm-up activity, this worksheet makes geometry accessible and enjoyable for kids.

Ideal for grades 3 to 5, this worksheet aligns with common core standards for geometry and measurement. It’s also a great supplement for homeschoolers or classroom teachers looking to add meaningful, skill-based practice to their lessons.
