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 10 September 'Starter of the Day' page by Carol, Sheffield PArk Academy: "3 NQTs in the department, I'm new subject leader in this new academy  Starters R Great!! Lovely resource for stimulating learning and getting eveyone off to a good start. Thank you!!" Comment recorded on the 19 October 'Starter of the Day' page by E Pollard, Huddersfield: "I used this with my bottom set in year 9. To engage them I used their name and favorite football team (or pop group) instead of the school name. For homework, I asked each student to find a definition for the key words they had been given (once they had fun trying to guess the answer) and they presented their findings to the rest of the class the following day. They felt really special because the key words came from their own personal information."

Finally there is a draganddrop standard form ordering activity.
Standard form, also known as scientific notation, is a way of conveniently writing numbers that accommodates values too large or small to be conveniently written in standard decimal notation.
3.48 x 10^{4}
= 3.48 x 10 x 10 x 10 x 10
= 3.48 x 10000
= 34800
3.48 x 10^{2}
3.48 x ^{1}⁄_{100}
= 3.48 ÷ 100
= 0.0348
Finally note that any number raised to the power zero is 1 so:
3.48 x 10^{0}
= 3.48 x 1
= 3.48
