# N2/L2.4

Use fractions to add, subtract, multiply and divide amounts or quantities

(a) Know some common addition and subtraction facts, e.g. 1/2 + 1/4 = 3/4;3/4 - 1/2 = 1/4

(b) Understand how to change fractions to equivalent fractions for the purpose of adding and subtracting

(c) Understand how to multiply a fraction by a fraction in practical contexts

(d) Understand division of fractions in practical situations

Another great worksheet in the never-ending Smarties series. Three level 2 tasks covering evaluating one number as a fraction of another, and adding and subtracting fractions. You will need at least one tube of Smarties.

A clever and unusual set of 3-way matching cards to help underpin the following skills: converting measures , expressing one number as a fraction of another, find parts of quantities, and simplifying fractions. Can be differentiated for E3-L2.

Forms part of a set of 5 resources linked to an excellent L1-2 lesson plan (that also focuses on expressing one number as a fraction of another). Can also be used independently.

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:

A fascinating way of tackling this often difficult-to-grasp skill. Very clever! More and more students seem to be using this method which requires multiplication and addition/subtraction.

A very clever spreadsheet that produces a constant supply of different worksheets with the click of a button (you must enable macros for the ‘recalculate’ button to operate). It produces a very nicely laid 1 page worksheets with a fold-over (or cut -off!) answer strip – each page has 16 questions covering addition, subtraction, multiplication and division of large numbers and fractions (some of the fraction questions are beyond the scope of the L2 curriculum but can easily be omitted).

Equivalent fractions – mixed numbers jigsaw is a 16 piece square jigsaw puzzle for learners to match up various numbers of halves and quarters to their equivalents. Use for revision or as a warm-up activity.

All Tarsia jigsaws can also be printed out as flashcards / dominoes.

You will need Tarsia Formulator in order to use this resource. See our Good Software – Tarsia Formulator entry for more information about this excellent free educational tool from Hermitech.

A set of very useful resources: detailed differentiated lesson plan (L1-2) lesson plan and two PPTs (one teacher version with answers, one student version) covering many aspects of L1-2 fractions. Generic examples and practice followed by practical applications and problems for students to work on in pairs or small groups. Examples include food/catering (a Greek party, sandwiches, etc.), production lines and time sheets.

Introduces fractions, explains numerators and denominators and then uses an edible task to teach evaluating one number as a fraction of another and adding fractions. Great for paired work (or small groups).
