We’re thrilled to announce an exciting expansion to our Grade 4 curriculum: an all-new set of geometry challenges awaits in Module 4, Topic C: Problem Solving with Angle Measure. 

This update is designed to help your fourth graders dig deeper into how angles combine and interact, offering engaging mathematical tasks that sharpen both understanding and skills all while helping a hamster plan his escape from the cage!

With this fresh addition, your Grade 4 students will move beyond just identifying and measuring angles on their own. Now, they'll be able to access real-world problems that involve putting angle measurements together using the concept of additivity. 

Topic C builds skills step by step, ensuring students gain a solid foundation before moving to more complex applications. 

They first learn to measure angles using a protractor and understand the symbols used in angle notation. Then, they explore the idea that larger angles can be divided into smaller ones or assembled from parts, preparing them for both single- and multi-step problems.

Students start by learning:

Once they’re confident, they then apply the principle of additivity (finding whole angles by adding the measures of their parts).

Students then use these skills to solve problems involving right angles, rectangles, and straight angles, which are shapes commonly encountered in Grade 4 geometry. This helps turn abstract ideas into practical understanding.

The module concludes by connecting geometry to basic algebra. In Tasks G and H, students use equations (rather than guessing) to solve single- and multi-step angle problems, like using the rule that a straight line measures 180 degrees. 

These challenges support critical thinking and will help your students see geometry as a set of interconnected concepts, not just isolated facts.

For Students: By blending geometry with algebraic thinking, this module makes math more connected and far more approachable. The accessible tasks build confidence and encourage students to see how numbers and shapes work together.

For Teachers: This update offers new ways to observe student progress as they approach problems with right angles, rectangles, and straight lines. The activities help to reveal students’ understanding of additivity and allow you to assess problem-solving abilities more clearly.

Take a moment to explore the new additions in Grade 4 Module 4, Topic C, found right in your teacher dashboard.
