Use this set of problem cards to get children thinking about place value with decimals.
What is decimal place value?
Decimal place value is a fundamental concept in mathematics, crucial for understanding numbers and performing arithmetic operations. It’s a key part of the Key Stage 3 (KS3) curriculum for pupils aged 11 to 14, and refers to the position of digits in a decimal number, determining their value based on powers of 10. For instance, in the number 345.678:
- Hundreds: 3 (300)
- Tens: 4 (40)
- Units (Ones): 5 (5)
- Tenths: 6 (0.6)
- Hundredths: 7 (0.07)
- Thousandths: 8 (0.008)
The KS3 Maths curriculum aims to:
- Develop fluency in mathematics through varied practice.
- Foster conceptual understanding and accurate application of knowledge.
