L2.3 Evaluate expressions and make substitutions in given formulae in words and symbols

Subject content [reformed] functional skills: Mathematics (DfE, Feb 2018):

An Australian version (i.e. uses A$, Australian vocabulary, etc.) of the popular Using Formulae v2 written by Gordon Noblett in 2007. Useful, realistic practice – questions cover mobiles, cooking, printing photos, plumbing rates, etc. Each multi-part question is cleverly staggered so that learners build up a set of answers and then find a 'rule'. Includes 'formulae expressed in words' so some questions also suitable for Level 1 (in addition to Level 2).

An Australian version (i.e. uses A$, Australian vocabulary, curriculum details, etc.) of the popular Using Formulae written by Jean Thomas in 2006. Covers substituting into formulae, percentages and working with large numbers.

This revision aid for L1/L2 (mainly L2) Pearson Edexcel Functional Skills maths gives a side-by-side comparison of perimeter, area and volume, the sort of units that would be involved with each and a worked Functional Skills example of each with a PAV mnemonic for remembering which is which. I have also looked through the last few years of Pearson Edexcel FS for the sorts of questions that require each one.

A set of Formula 1 scenarios based on the four rules of mathematics and using formulae expressed in words and/or numbers. This resource tests students’ ability to use formulae to solve problems based on a motor racing car travelling on a race track. Some of the scenarios test the students ability to convert units to get a sensible answer. I encourage my students to estimate the answers before attempting for real! Some do, some don’t …
