### 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

### 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.

### Keywords

Compare - When you compare, you look for similarities and differences in an object or value.
