In S3, students develop their skils from S1 and S2, and start to lay the foundations for study in S4 and S5. They begin the year by reviewing and extending learning around fractions, decimals and percentages. This is followed with being introduced to an increasingly important area of Mathematics: Pythagoras' Theorem and Trigonometry. Students will develop their algebraic skills to incorporate more complicated expressions such as quadratics. The geometry topics in this year focus on working in the coordinate plane, including transforming shapes.
S3 students begin to learn some of the higher level skills required to support further study in Mathematics. Trigonometry and Quadratics are two very important topics that students will continue to develop until they leave school, and it all begins in S3.
S3 Key Skills
S3 Key Skills
In each year group there are some key skills that we want students to master completely by the end of the year. Fluency in these keys skills will help students in future years as these become building blocks for other skills they will develop:
In S3 the Key Skills are:
