Estimate answers to calculations.

(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.)

I have created this to enable learners to estimate and calculate and to emphasis the (financial) costs of smoking.**Editor’s note**

With Functional maths mapping.

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.

A very clear, step by step worksheet that makes a great introduction to this important topic. It’s also ideal for underpinning Functional Maths.

Lots of sequential practice working out percentage parts, increase, decrease and VAT. Three fill-in tables, all based on 4 large mountain bike posters.

Darcy v Wickham! A great way to introduce students to estimation and ‘what is reasonable’.
