Rounding Starters:Absolutely Everyone: A choice of questions about the current world population which is constantly changing. Moon Lengths: Estimate the distances shown on this photograph of the moon's surface. Pi Day: March 14th is Pi Day. The third month and the 14th day relates to 3.14 which is pi to three significant figures. How many figures of pi can you memorise? Rounding 1dp: Round off the given numbers to 1 decimal place then add the answers together. Rounding 2dp: Round off the given numbers to 2 decimal places then add the answers together.

Curriculum for Rounding:Year 5Pupils should be taught to use rounding to check answers to calculations and determine, in the context of a problem, levels of accuracy more... Pupils should be taught to round any number up to 1 000 000 to the nearest 10, 100, 1000, 10 000 and 100 000 more... Pupils should be taught to round decimals with two decimal places to the nearest whole number and to one decimal place more... Year 6Pupils should be taught to round any whole number to a required degree of accuracy more... Pupils should be taught to identify the value of each digit in numbers given to three decimal places and multiply and divide numbers by 10, 100 and 1000 giving answers up to three decimal places more... Pupils should be taught to use estimation to check answers to calculations and determine, in the context of a problem, an appropriate degree of accuracy. more... Pupils should be taught to solve problems which require answers to be rounded to specified degrees of accuracy more... Years 7 to 9Pupils should be taught to round numbers and measures to an appropriate degree of accuracy [for example, to a number of decimal places or significant figures] more... Pupils should be taught to use approximation through rounding to estimate answers and calculate possible resulting errors expressed using inequality notation a<x≤b more... Years 10 and 11Pupils should be taught to apply and interpret limits of accuracy when rounding or truncating, {including upper and lower bounds} more... 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 28 May 'Starter of the Day' page by L Smith, Colwyn Bay: "An absolutely brilliant resource. Only recently been discovered but is used daily with all my classes. It is particularly useful when things can be saved for further use. Thank you!" Comment recorded on the 10 April 'Starter of the Day' page by Mike Sendrove, Salt Grammar School, UK.: "A really useful set of resources  thanks. Is the collection available on CD? Are solutions available?" Comment recorded on the 18 September 'Starter of the Day' page by Mrs. Peacock, Downe House School and Kennet School: "My year 8's absolutely loved the "Separated Twins" starter. I set it as an optional piece of work for my year 11's over a weekend and one girl came up with 3 independant solutions." Comment recorded on the 11 January 'Starter of the Day' page by S Johnson, The King John School: "We recently had an afternoon on accelerated learning.This linked really well and prompted a discussion about learning styles and short term memory." Comment recorded on the 9 May 'Starter of the Day' page by Liz, Kuwait: "I would like to thank you for the excellent resources which I used every day. My students would often turn up early to tackle the starter of the day as there were stamps for the first 5 finishers. We also had a lot of fun with the fun maths. All in all your resources provoked discussion and the students had a lot of fun." Comment recorded on the 17 June 'Starter of the Day' page by Mr Hall, Light Hall School, Solihull: "Dear Transum, Comment recorded on the 8 May 'Starter of the Day' page by Mr Smith, West Sussex, UK: "I am an NQT and have only just discovered this website. I nearly wet my pants with joy. Comment recorded on the 1 February 'Starter of the Day' page by Terry Shaw, Beaulieu Convent School: "Really good site. Lots of good ideas for starters. Use it most of the time in KS3." 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!!" 
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 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. Rounding 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.
