S2

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 S2 the Key Skills are:

• using formulae

• the difference between linear and non-linear sequences

• finding the nth term of linear sequences

• the Fibonacci sequence and other famous sequences

In this unit students will learn about:
