AN N1/L2.4

Evaluate expressions and make substitutions in given formulae in words and symbols to produce results (a) Understand that words and symbols in expressions and formulae represent variable quantities (numbers), not things (i.e. 2a + 2b cannot be explained as 2 apples and 2 bananas) (b) Understand that the contents of brackets must be worked out first (c) Understand that, when there is no operator between a number and a variable, or two variables, multiplication is implied, e.g. 2a = 2 x a; ab = a x b; 2ab = 2 x a x b (d) Understand that, when there is no operator between a number and a bracket, multiplication is implied, e.g. 2 (a + b) = 2 x (a + b)

This is a handout for Functional Skills L1/L2 which talks about formulas, substitution and BODMAS (BIDMAS).

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 …

Functional Maths - numbers and the number system

12 very useful multiple choice, topic-based Functional Maths questions.
Ideal for assessment or revision.

Functional Maths - numbers and the number system

This PowerPoint was used to introduce Pythagoras’ Theorem to Functional Skills college students whose main course work is to do with the Building Trades (Carpenters, Electricians). The last 4 slides therefore deal with using Pythagoras’ theorem to calculate the length of roof rafters.

Editor’s note
I realise that using Pythagoras’ theorem is beyond the scope of L2 Functional Maths Exams but this is a very useful PPT due to the vocational questions. Would also be useful for GCSE Maths.

A power point and interactive cards to introduce the students to reversing calculations / formulas.

The animated PPT demonstrates the basics of how to rearrange formulae and use reverse calculations to self check answers.

The cards with symbols, can be used to physically rearrange the formula showing the moves of each symbol. These allow the tutor to spend some time talking the less able students through the process. Students can then use the card to complete a short worksheet.

A set of two posters for the classroom – also useful as handouts.
Formulae (L2)
I asked a group of my learners to come up with a short and snappy set of rules for using formulae. One of the group wrote the rules in the form of a poster, from which I developed this poster.
Covers general rules for using formulae such as order of operations (BIDMAS). Plus a separate page specifically for using a formula to find the area of a circle.

Three fabulous PPTs – great for St George’s day but could be used year round.
The full length one (22 slides) was written for a 2.5 hour observed session and has in-depth coverage of multiplying decimals; area of rectangles, triangles, circles and compound shapes; substitution; and a general warm-up quiz.
There are alternative shortened versions (some activities are slightly different too) for a 1 hr L1 lesson (area of rectangles) and a 1.5 hr L1-2 Lesson (no triangles).

A revision of L1 numeracy skills all themed around England. Written for St George’s Day but can be used any time of year. Great for equality and diversity. Question themes include: population of UK districts, languages spoken in London, major religions, planning a St George’s Day street party. Topics covered include calculating and converting measures, working with large numbers, representing data, ratios, fractions, percentages and substitution.
