Feedback:Comment recorded on the 19 June 'Starter of the Day' page by Nikki Jordan, Braunton School, Devon: "Excellent. Thank you very much for a fabulous set of starters. I use the 'weekenders' if the daily ones are not quite what I want. Brilliant and much appreciated."

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:Rough Answers: An exercise on rounding values in a calculation to find an approximate estimate of the answer. 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.
