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 9 May 'Starter of the Day' page by Liz, Kuwait:

"I would like to thank you for the excellent resources which I used every day. My students would often turn up early to tackle the starter of the day as there were stamps for the first 5 finishers. We also had a lot of fun with the fun maths. All in all your resources provoked discussion and the students had a lot of fun."

Comment recorded on the 25 June 'Starter of the Day' page by Inger.kisby@herts and essex.herts.sch.uk, :

"We all love your starters. It is so good to have such a collection. We use them for all age groups and abilities. Have particularly enjoyed KIM's game, as we have not used that for Mathematics before. Keep up the good work and thank you very much
Best wishes from Inger Kisby"

One way to address the problem is through the use of interactive activities and this web site provides many of those.

Example

The sum of two numbers is the total you get when you add the numbers together.

The product of two numbers is the total you get when you multiply the numbers together.

Subtract means take away!

Dividing by twenty is a lot to ask,

But an easier method will help you.

Dividing by ten is a much easier task,

Then divide your answer by two!
