Extra activity  

This activity is for stronger classes. In pairs, 

one student explains the location of a 

component in their own words. The other 

student says what the component is.  

Language  

 

The focus here is two-fold: saying decimal 

numbers and using prefixes common in IT for 

expressing large numbers (for example, mega- 

for ‘million’). You could talk about conventions 

in the writing of numbers that may be different 

in students’ own countries. For example, some 

countries use a comma for the decimal point; 

this can be confusing to people from other 

countries in which the comma is used to 

separate groups of three digits to the left of the 

decimal point (for example, in 1,034.434). Point 

out that the decimal point is not stressed. 

4

  Students match prefixes to the numbers they 

represent. While students do this, make sure 

they are saying the numbers correctly, following 

the first focus of the Language box (for example, 

nought point nought nought one). It may help 

students to think of the abbreviation for the 

numbers in their own language; KB is used for  

‘a thousand bytes’ in many languages.
