What does this mean?
Numbers up to ten million are read in groups of three digits, working from the millions down to the ones. Commas mark each group to make the number easier to read.
Key words:
- Digit A single number symbol, 0 to 9.
- Partition Split a number into parts, usually by place value.
- Place value What a digit is worth because of where it sits. The 3 in 30 is worth thirty.
- Rounding Replacing a number with a nearby, simpler one.
The key rule
Split the number into groups of three digits from the right.
In words:
- Read the millions, then the thousands, then the rest.
- Compare numbers by their highest place value first.
Remember
Each comma separates a group of three digits.
