This digital sorting activity helps students practice simplifying square roots involving real and imaginary numbers in an engaging, paperless format using Google Slides™. Perfect for Google Classroom™, distance learning, or 1:1 classrooms.

Students reduce square roots with both positive and negative radicands and determine when to use an imaginary unit (i) versus a negative sign. Cards are sorted by drag-and-drop, allowing students to actively engage with patterns in square root simplification.

For each perfect square from 1 to 64, students simplify all four variations:
√a, √(–a), –√a, and –√(–a)
