# Scale matters: all numbers: assessment

TLF ID L8629

Test your understanding of the use of scales, ranging from tens of thousands or thousands through to ones, tenths or hundredths. Look at two numbers and place a third number on a number line. Rename the third number by assigning place values for each digit or group of digits. For example, look at the numbers 105 384 and 105 392 on a number line and select 'Ones' as the most useful scale to locate the given number 105 387. Rename 105 387 as 10.5 tens of thousands and 38.7 tens. See a report of your results. This assessment object is one in a series of three objects.
