Why am I learning this?

Mathematicians are not the people who find Maths easy; they are the people who enjoy how mystifying, puzzling and hard it is. Are you a mathematician?

Comment recorded on the 14 September 'Starter of the Day' page by Trish Bailey, Kingstone School:

"This is a great memory aid which could be used for formulae or key facts etc - in any subject area. The PICTURE is such an aid to remembering where each number or group of numbers is - my pupils love it!
Thanks"

Go Maths

Learning and understanding Mathematics, at every level, requires learner engagement. Mathematics is not a spectator sport. Sometimes traditional teaching fails to actively involve students. One way to address the problem is through the use of interactive activities and this web site provides many of those. The Go Maths page is an alphabetical list of free activities designed for students in Secondary/High school.

"This is an excellent activity to make pupils think about the structure of a sequence rather than just learning a set of rules. It has worked very successfully for eleven year olds as well as sixteen year olds and is also an activity that can be done by pupils working in pairs. When pupils work with others the conversation about the methods they are using is very revealing."

Help

Levels 1 and 2 consist of arithmetic sequences where each term is a fixed amount more than the previous term.

If the first term is a and the fixed amount (common difference) is d then the nth term is:

a + (n−1)d

Level 3 consists of geometric sequences where each term is the the previous term multiplied by a fixed amount.

If the first term is a and the fixed amount (common ratio) is r then the nth term is:

a × rn−1
