The ability to estimate values is an often overlooked part of Mathematics. Estimating lengths, weights, time, angles and solutions to problems should be practised regularly. Pupils should make sensible estimates of a range of measures in relation to everyday situations.
Estimating: Estimation is a very important skill. Use this activity to practise and improve your skills.
Estimating Angles: Estimate the size of the given acute angles in degrees.
Estimating Percentages: Estimate the percentages represented by the diagrams.
Estimation Golf: Play a round of golf using your estimation skills rather than golf clubs.
Rough Answers: An exercise on rounding values in a calculation to find an approximate estimate of the answer.
Snooker Angles: An online game for one or two players requiring an ability to estimate angles.
Counting Crowds: Find out how statisticians use density samples to estimate their statistics.
Estimate Enormous Numbers: Learn how to use the powers of 10 to make amazingly fast estimations of big numbers with this animated explanation.
Take Sides Questions: Thirty pairs of numbers or calculations. Which one of the pair is the largest?
