starts by counting on
fraction sequences with their 'simplest' (cancelled) form on the powerpoint
this could be done orally, with some explanations sought
then finding three missing terms and a general rule (nth term) for a fraction sequence
with (assumed) regular increases on the first resource
and a regular pattern (nth term) for the numerators and the denominators on the second resource
students might need nudging to consider equivalent fractions - hopefully not...
