Introduction to Surds and Radicals
Students are introduced to surds and radicals, learning about the concept of irrational numbers and how to simplify square roots and higher-order roots. They explore the basic properties of radicals and how to perform simple operations with them. By Year 5, students have a solid understanding of how to manipulate and simplify expressions involving surds, preparing them for advanced topics in algebra and trigonometry.
Simplifying Surds
Starting with simple exercises to simplify square roots, students learn techniques to simplify surds by factoring numbers into primes and identifying perfect squares. They practice rationalising denominators and simplifying expressions involving surds. By Year 5, students can simplify complex surds and combine surds with other algebraic terms in expressions, enhancing their skills in algebraic manipulation.
Operations with Radicals
Initially, students perform basic operations with radicals, including addition, subtraction, multiplication, and division. They learn to simplify expressions before performing these operations and explore the rules for combining radicals. By Year 5, students proficiently perform complex operations with radicals, applying these operations in the solution of equations and in simplifying algebraic expressions.
