# N1/L1.9

(a) know how to make approximate calculations
(b) understand that a knowledge of context enables "guessing" at answers (e.g. it should be about ...), or judging if answers are sensible (e.g. that's far too big; it doesn't make sense to have an answer less than 1, etc.)

## Stoptober maths - the cost of smoking

I have created this to enable learners to estimate and calculate and to emphasis the (financial) costs of smoking.

## Multiple choice numeracy revision cards

Five wonderful sets of multiple choice revision questions covering Level 1 ratio, mean & range, fractions, percentages, and number (mostly place value & rounding). Each set consists of 9 cards and is individually mapped to the numeracy curriculum.
Cut up into cards and use as required. Use individual sets for targeted revision or mix with other sets of cards for general revision.
