# N2/E3.4

Use a calculator to calculate using whole numbers and decimals to solve problems in context, and to check calculations

(a) Know how to key in and interpret money calculations e.g. key in 85p as 0.85, interpret 8.2 as £8.20

(b) Understand that a calculator will sometimes display a string of digits after the decimal point, and that it is only necessary (at this level) to read the first two, e.g. 1.33333333 is £1.33

(c) Know and use strategies to check answers obtained with a calculator

In this activity, learners have to calculate how much paint is required for a specified job, find prices from different sources and work out total prices. This can then be compared. The resource is in two versions – one with formulae for the required calculations and one without – different pages from each version can be mixed and match to meet different learners’ needs.

The activity requires internet access – however price lists could be substituted for this if this is not available in your context.

Working out weekly wages and then comparing, ordering and rounding your results. Includes information on the UK minimum wage – which makes an ideal discussion prompt.

Village Fair – calculator calculations is a great way to practise money based problem solving on a calculator. It is followed by a fun set (30+ problems) of ‘calculator words’ where you must complete the given calculation and then turn your calculator upside down!

Entry level lottery activity that involves deciding how you are going to spend the money. Structured, with fill-in boxes for expenditure etc.

Written for learners on the autistic spectrum (who often find it particularly difficult to infer meaning that is not explicitly stated) but suitable for many literacy and/or numeracy students.

A differentiated whole group (E1 – L2) activity that’s ideal for the first class after the summer break.

Great series of differentiated assignments (2 each at Entry 2, Entry 3 and Level 1) using the Royal Mail web site or leaflets (last posting dates, parcel prices) for the postage assignments, and an Argos (or similar) catalogue for the Christmas present assignment. Topics covered include reading tables, weighing, working with decimals and money, using calculators.
