# N2/L1.10

Find simple percentage increases and decreases

(a) Understand that a percentage increase can be found by finding the percentage part and adding on

(b) Understand that a percentage decrease can be found by finding the percentage part and subtracting

PPT covering

- Percentages of simple amounts (10%, 50% etc).
- More challenging amounts (e.g 15%)
- Percentage increase and decrease.

Each objective has examples, followed by tasks.

I have created this worksheet to assess learners studying maths at level 2 in solving practical problems which involve extracting and interpreting discrete data from a table and also calculating a percentage increase.

**Editor’s note**

With Functional Maths and Adult Numeracy curriculum mapping

An activity using mobile phones. Students could also do a warm-up by measuring and weighing real phones (switched off)!

The lesson was designed for an E3 young learner class. The last section, using percentage changes, might suit stronger learners (L1 extension).

**Editor’s note**

Fully mapped to the Functional Maths criteria. Covers rounding whole nos. and decimals, money, percentages, fractions and area.

A set of cards that can be used to play a game where students have shares in a small company. Each group of three players receives ‘market updates’ in the form of cards that require them to divide a number in a ratio, or find the value of an amount given the value of part of the amount. Students are encouraged to keep full financial records. As a differentiation task for confident students, it is possible to calculate the percentage change in value of the shareholding at the end of the game.

Beautifully clear worksheet to be used in conjunction with John Thomson’s “percentage worker-outer” (see below). It is staggered to build up skills slowly – making it particularly good for the less confident learner who needs lots of practice.

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.

This spreadsheet is designed to enable students to check their own work; but also to learn about what happens when you add two decimals, or multiply two fractions, and so on.

The spreadsheet consists of the following sheets:

Two workbooks, both with an accompanying PPT. Directly related, in terms of theory, to the VRQ qualification, the Foundation Diploma and also ABC Level 1 Catering.

**Profit and loss** workbook covers gross profit, net profit, percent gross profit and calculating selling prices of a dish.

[img_assist|nid=4265|title=|desc=|link=popup|align=left|width=47|height=100]*How do I cost a dish?* workbook covers costing individual ingredients and entire dish along with extension activities.

A fabulous, very clear lesson plan ideal for money-management / personal finance classes. The mathematical focus is on percentages (VAT) but it also covers rounding and extracting data and can be used in mixed ability classes from E2 -L2.

The plan also includes links to online Budget videos, a ‘chop or not’ game, VAT calculators and more!

Also suitable for underpinning L1 Functional Maths, and linked to Education for Sustainable Development and Global Citizenship (ESDGC).

Practise percentages starts with a some questions based on the results of a survey in a college canteen – emphasising that percentages are ‘out of 100’. There is also a separate set of simple percentage increase / decrease questions.
