Compare and order numbers with up to 3 decimal places
Lesson details
Learning outcome
I can use understanding of place value to compare and order numbers with up to 3 decimal places
Key learning points
- To compare two numbers, you compare digits with the same place value, starting with the largest place-value digit
- If whole numbers. tenths and hundredths are the same, look at the value of the thousandths digit to compare and order
Keywords
Compare - When you compare, you look for similarities and differences in an object or value.
Place value - The value of a digit in a number based on where it is placed is known as place value.
Order - You can order numbers by putting them in a place based on a set rule.
Common misconception
Pupils mistake numbers with more digits after the decimal point to be the larger number.
Provide opportunities for pupils to build numbers with base 10 blocks, enabling them to see the magnitude of the numbers they compare.
Teacher tip
Use the stem sentence 'I say ___ point ___ ___ ___ but I think ___ wholes and ___ tenths/hundredths/thousandths to help pupils readily convert between each value to compare more easily.
