Feedback: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 November 'Starter of the Day' page by Amy Thay, Coventry: "Thank you so much for your wonderful site. I have so much material to use in class and inspire me to try something a little different more often. I am going to show my maths department your website and encourage them to use it too. How lovely that you have compiled such a great resource to help teachers and pupils. Comment recorded on the 16 March 'Starter of the Day' page by Mrs A Milton, Ysgol Ardudwy: "I have used your starters for 3 years now and would not have a lesson without one!

Is the collection available on CD? Are solutions available?" 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."

Notes:The objective of rounding is often to get a number that is easier to use, 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.
Rounding Teacher Resources:Decimals Line: A number line showing tenths and hundredths with draggable arrows. This is a visual aid designed to be projected onto a whiteboard for whole class exposition 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 Activities:Rounding Ten: Round the numbers to the nearest whole number or the given power of ten. 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! Rough Answers: An exercise on rounding values in a calculation to find an approximate estimate of the answer. Upper and Lower Bounds: Determine the upper and lower bounds when rounding or truncating quantities used in calculations. Rounding Videos:Rounding Video: A reminder of how to round numbers to significant figures, decimal places and to the nearest power of ten. Upper and Lower Bounds Video: A reminder of how to find the limits of accuracy of rounded values. Rounding Worksheets/Printables:Rounding Snap Cards: Printable cards for the Rounding Snap game.

"Who was the first person to put two feet on the top of Everest?
It was Radhanath Sikdar who had a special aptitude for trigonometry. Back in the 1850s he used a theodolite located 150 miles away to measure the height as being exactly 29,000 feet. He thought people would not be impressed with the accuracy of his measurement as it was a multiple of a thousand so he added two feet to make the measurement 29,002 feet. Thus he became the first person to put two feet on the top of Everest!
Quite Interesting!"

"Do you need an interesting story to tell when teaching Rounding? I read in The Times newspaper that "There was some hand-wringing at MI5 in 2010 when the government admitted that 'a formatting fault on an electronic spreadsheet' had led to the Security Service and the Serious Organised Crime Agency to tap 134 incorrect telephone numbers. A user had told the program to round up the numbers so that it changed the last three digits to zeros.""
