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 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.

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 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. Approximation 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.
