Decimals and place value
What decimals and place value means
You learn how to read the value of each digit after the decimal point and compare decimal numbers correctly. This helps you work out prices, measurements and simple calculations in everyday maths.
What you will practise
- Identify tenths, hundredths and thousandths in decimal numbers.
- Compare two decimals by looking at place value.
- Line up decimal points before adding decimals.
- Find the value of a digit in a given decimal.
Before you start
You should already know whole number place value and the names of digits in ones, tens and hundreds. It also helps if you can count in tenths and read simple fractions like halves and quarters.
Worked example
One question from this skill's own question bank, shown with its full working.
What is the value of the 5 in 3.25?
- 5 tenths
- 5 hundredths
- 5 ones
- 5 tens
Working: In 3.25 the 5 is in the hundredths place.
Common mistakes to avoid
- Reading 0.7 as smaller than 0.65 because it has fewer digits. Write it as 0.70 before comparing.
- Treating the digit after the decimal point as a whole number. Check whether it is in tenths or hundredths.
- Adding decimals without lining up the decimal points. Keep the points in one column before you add.
- Ignoring place value when finding a digit's value. Say the full value, not just the digit.
Curriculum and exam alignment
In Upper Primary, this kind of work usually appears after pupils are secure with whole number place value and before more advanced number topics. It supports school-based assessment and gives useful practice for the kind of decimal questions that build the groundwork for the BECE.
Curriculum notes are a general guide to where this work normally sits. Always check the syllabus your school or examination body is currently using.
