Identifying decimal digits for 11+ maths
21 October 2026
Why decimal digits matter
Understanding decimal digits is key for 11+ maths. Children often need to spot, name or use digits in tenths, hundredths and thousandths places. This skill supports calculation and problem-solving throughout the exam.
Decimal places explained
Each place after the decimal point has its own value. The first digit is the tenths, the second is the hundredths, and the third is the thousandths. Knowing these positions helps children answer questions quickly and accurately.
Key insight: The position of a digit changes its value
A 7 in the tenths place is worth much more than a 7 in the thousandths place. Encourage your child to read decimal numbers carefully, focusing on the position of each digit after the decimal point.
Worked example
In the number 3.476:
3 is the whole number part, before the decimal point.
4 is in the tenths place, so it represents four tenths (0.4).
7 is in the hundredths place, so it represents seven hundredths (0.07).
6 is in the thousandths place, so it represents six thousandths (0.006).
The correct answer is: 4 is the tenths digit, 7 is the hundredths digit, and 6 is the thousandths digit.
Helping your child practise
Ask your child to identify digits in different decimal numbers. For example, what is the hundredths digit in 2.539? (Answer: 3.) Practise with numbers up to three decimal places to build confidence.
Summary: building strong foundations
By recognising and naming decimal digits, your child will be ready for more complex decimal questions in the 11+ exam. This basic skill supports many areas of maths and helps avoid common mistakes.
