# N1/E3.7

Approximate by rounding numbers less than 1000 to the nearest 10 or 100
(a) Understand place value for units, tens, hundreds

## Functional Skills mobile phone investigation

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.

## Interactive rounding resources

Introduce the topic using the Smart Notebook activity.
8 identical pages, each with a blank number line, a movable arrow to show the position of the number to be rounded and a sentence at the bottom to state what is happening.
Learners can fill in the ends of the number line to see what values are relevant to the question i.e. rounding 23 to the nearest 10 would be either 20 or 30 as an answer. Then they can move the arrow to the position needed, 23, then see which value the number is closest to.

## The Budget

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).

## Rounding

Rounding presentation makes clever use of number lines and animation to demonstrate rounding whole numbers (nearest 10, 100, 1000) and decimals (nearest whole number, 1 and 2 d.p.) and using significant figures. Please ensure that you also download the accompanying PDF document (see below) with useful teaching notes and ideas for adapting the PPT for your own learners.
