Terminating and Recurring Decimals - Recurring Decimals to Fractions

A big value bundle which would form the basis of a 2 or 3 lesson block on this topic.

First lesson - why do some decimals terminate and some decimals recur? - getting students to find for themselves through division and investigation that this relates to the prime factors of the denominator.

Second / Third lesson - plenty of work / practice including a well graded Mild / Hot / Spicy / Inferno sheet for this tricky topic.
