Approximation WORKSHEET
Approximation WORKSHEET DESCRIPTION
This worksheet focuses not only on rounding but also choosing suitable values for estimating answers to calculations.
Section A asks learners to complete a large table where they need to choose suitable values to approximate the answer to a calculation as well as find the actual answer. Learners will need to be aware that sometimes rounding to 1 significant figure is not always the best method when estimating some calculations.
Section B then provides six-worded problems involving estimation.
All worksheets are created by the team of experienced teachers at Cazoom Maths.
