Start with a preliminary investigation into which fractions make
Allow students to use electronic calculators and also
(essential) to experiment with a standard non-calculator method for
the division, to acquire a feel for the elements involved in
'decimalising' a fraction.
Once the group can see which fractions will lead to recurring
decimals, and can really understand why, present the Tiny Nines
Activity which concentrates on changing decimals to fractions
and fractions to decimals to important work. Ask students to make
up a set of eight fractions which don't seem particularly related.
Ask then to guess the order of the fractions, smallest to
Direct them to convert each fraction to its decimal form and
compare, and then challenge them to find a way to get this ordering
right every time, whatever the fractions.
