Estimating (A) WORKSHEET
Use rational approximations of irrational numbers to compare the size of irrational numbers, locate them approximately on a number line diagram, and estimate the value of expressions (e.g., π2). For example, by truncating the decimal expansion of √2, show that √2 is between 1 and 2, then between 1.4 and 1.5, and explain how to continue on to get better approximations.
Estimating (A) WORKSHEET DESCRIPTION
This worksheet focuses not only on rounding, but also on 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 word problems involving estimation.
