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 7 December 'Starter of the Day' page by Cathryn Aldridge, Pells Primary:

"I use Starter of the Day as a registration and warm-up activity for my Year 6 class. The range of questioning provided is excellent as are some of the images.
I rate this site as a 5!"

Comment recorded on the 11 January 'Starter of the Day' page by S Johnson, The King John School:

"We recently had an afternoon on accelerated learning.This linked really well and prompted a discussion about learning styles and short term memory."

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 exercise is a follow-on activity from the Starter Of The Day of the same name. It is intended to refine the quick method and adding up numbers once the trick has been learned. It makes a good introduction to finding a general formula for the sum of any arithmetic series."

This is a very slow way to add together the numbers from one to ten:


It is much more efficient if you think of the numbers in pairs like this:

[1+10], [2+9], [3+8], [4+7] and [5+6]

There are five pairs and each pair adds up to eleven so the total is:

5 × 11

= 55

An animated visualisation of this technique can be seen by pressing the 'Show a hint' button on the 26th February Starter of the Day page.

The general formula for finding the sum of a sequence of numbers is to find the number of terms, multiply it by the first term added to the last term and then divide the answer by two.

This is the formula for an arithmetic sequence, one in which the difference between consecutive terms is always the same.

This formula does not apply to the last question in Level 3!!!
