Journey Through Time and Space to Learn Angle Measurement: New Updates in Grade 4

In the latest update, we’ve introduced exciting new content to help students dive into the world of angle measurement with a fun, space-themed adventure. 

This update builds on foundational concepts like degrees, the protractor, and measuring angles, offering a structured, engaging learning experience.

What’s New in Angle Measurement?

This new content introduces students to the concept of angles and their measurement in degrees. They start by exploring the idea that a full circle is divided into 360 degrees, with each degree representing 1/360th of the circle. Students begin by learning to use a protractor to measure simple angles, with a focus on identifying 90° angles. These early tasks help students develop a clear understanding of the degree symbol and how to represent angles accurately.


The update progresses gradually, allowing students to tackle more complex tasks as they advance. Initially, students use a protractor with a single scale to measure angles. As they grow more confident, they are introduced to protractors with dual scales, helping them choose the correct scale for easier reading. Eventually, students will learn to rotate the protractor itself in cases where the angle is turned, teaching them a crucial skill for measuring angles in a variety of real-world situations.


The updated content is framed within a captivating storyline, where students embark on a space voyage through time and space. From Babylon to Ancient Greece and modern times, our cosmic travelers will encounter different civilizations and learn about angels in various historical contexts. This engaging narrative makes the learning process feel like an adventure, sparking curiosity and making abstract concepts like measuring angles more concrete and memorable.

Why These Updates Matter

For Students: This updated storyline adds an exciting, interactive dimension to learning about angle measurement. With the fun, space-themed backdrop, students are more likely to stay engaged while developing their skills in measuring angles. The gradual progression from simple to complex tasks ensures that students master the fundamentals before moving on to more challenging concepts, setting the stage for advanced geometric skills.

For Teachers: These new tasks and visualizations make it easier to teach students the nuances of angle measurement. Whether it’s using a protractor to measure angles, or building an angle based on a given degree measurement, the updates allow teachers to guide students through every step with clarity. The storyline-based approach also adds a dynamic, fun element to your lessons, helping students stay motivated.
