Exemplars (from the NaCCA curriculum)
E.g. 1. Explain the rule for of rounding decimals, which is similar to that of rounding whole numbers. That is, rounding to the nearest tenth means that the rounded figure has one digit after the decimal mark. Rounding to the nearest hundredth means that the rounded figure has two digits after the decimal mark E.g. 2. Use a table with several decimals fractions and explain the rule for of rounding decimals. Give pupils a table of decimal fractions to round to the nearest tenths or hundredths
E.g. 3. Ask students to change fractions to decimal writing their results to the nearest tenths or hundredths
The E.g. 3 table (Fraction / Round to Nearest / Result, rows A 0.38 to E 30.084) is set below the exemplar and its cells interleave with the text; the figure shows it.
