You are often asked to give answers as exact values. In this task you will use the Geogebra to explore irrational numbers (surds) and their decimal approximations by sketching a surd spiral.
In this engaging Geogebra class activity, students will dive into the world of exact values and their numerical approximations by constructing a Surd Spiral. The Surd Spiral is a captivating geometric pattern that incorporates square roots of integers to create a visually stunning design. This activity serves as a bridge between algebraic concepts and geometric representation. Students will gain a better appreciation for the role of exact values in mathematics and when and why numerical approximations are used. This interactive and visual approach will make abstract mathematical concepts more tangible and relatable, helping students develop a deeper understanding of surds and their applications.
