Function Machines and mapping diagrams

(0)
This is part of a series of lessons on straight line graphs. This is suitable for mixed ability KS3. This lesson links some aspects of functions and sequences using mapping diagrams

Plotting straight line graphs

This is a fully animated lesson on plotting straight line graphs. It is the third lesson in a series which starts on function notation and builds to straight line graphs. This looks at the need for a table compared with a mapping diagram. Suitable for GCSE but it is worth noting mapping diagrams dont lend themselves to quadratics so they need to be familiar with both

nth terms of an arithmetic sequence

This is lesson 3 of a series of lessons. It looks at the nth term as a shift from any timestable. The numberline is the under lying structure to everything. The link to the recurrence relationship is key. There is a worksheet that goes with this lesson

Sequence finding terms in a sequence

This has been designed for mixed ability KS3 (Year 9). The link between recurrence relations and term to term is brought in to highlight the notation we need later in iterations. For the nurture groups we have we removed the recurrence notation.

Finding the nth term of an arithmetic sequence

(0)
This is the second lesson in a series where we look at how a sequence relates to a multiple. It uses numberline as a structure and in this lesson it just looks at how sequences shift from the two times table. There is a lot of linking to term to term and recurrence relationships as this is the starting point to the series of lessons. Everyhting is developed to make a link between sequences and straight line graphs
