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!"
