Feedback:Comment recorded on the 24 May 'Starter of the Day' page by Ruth Seward, Hagley Park Sports College: "Find the starters wonderful; students enjoy them and often want to use the idea generated by the starter in other parts of the lesson. Keep up the good work" Comment recorded on the i asp?ID_Top 'Starter of the Day' page by Jan, South Canterbury: "Thank you for sharing such a great resource.

I use the 'weekenders' if the daily ones are not quite what I want. Brilliant and much appreciated." 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!

Comment recorded on the 17 June 'Starter of the Day' page by Mr Hall, Light Hall School, Solihull: "Dear Transum, Comment recorded on the i asp?ID_Top 'Starter of the Day' page by Peter Wright, St Joseph's College: "Love using the Starter of the Day activities to get the students into Maths mode at the beginning of a lesson. Lots of interesting discussions and questions have arisen out of the activities. Comment recorded on the 1 February 'Starter of the Day' page by M Chant, Chase Lane School Harwich: "My year five children look forward to their daily challenge and enjoy the problems as much as I do. A great resource  thanks a million." 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." Comment recorded on the 2 May 'Starter of the Day' page by Angela Lowry, : "I think these are great! So useful and handy, the children love them. Comment recorded on the 10 April 'Starter of the Day' page by Transum, : "Sorry Mike, because some of the starters link to live data on the Internet there is no CD version. Thanks for your comments."

Are solutions available?"

Comment recorded on the 26 March 'Starter of the Day' page by Julie Reakes, The English College, Dubai: "It's great to have a starter that's timed and focuses the attention of everyone fully. I told them in advance I would do 10 then record their percentages." Comment recorded on the 23 September 'Starter of the Day' page by Judy, Chatsmore CHS: "This triangle starter is excellent. I have used it with all of my ks3 and ks4 classes and they are all totally focused when counting the triangles."

Notes:Approximating a quantity is often to get a value that is easier to use or understand, at the cost of making it less precise. This approximation is very important in dealing with answers to mathematical problems and making them relevant to the real world. Rounding to a given number of decimal places or significant figures is required of pupils. Approximation Teacher Resources:Rounding Snap: If the last card put down equals the previous card to the nearest whole number then all players race to shout SNAP! Approximation Activities:Rounding DP: A self marking exercise requiring students to round numbers to a given number of decimal places. Rounding SF: A self marking exercise requiring students to round numbers to a given number of significant figures. Rounding Snap: If the last card put down equals the previous card to the nearest whole number then all players race to shout SNAP! Rounding Ten: Round the numbers to the nearest whole number or the given power of ten. Upper and Lower Bounds: Determine the upper and lower bounds when rounding or truncating quantities used in calculations. Approximation Videos:Rounding to decimal places: A straight forward explanation from SLEP Rounding to significant figures: A straight forward explanation from SLEP Significant Figures: A CGP Maths Tutor explains what 'significant figures' are then talks you through some examples in this video tutorial.
