- Problem Solver:
- I don't think so, but now I remember, standard form is just the regular way to write a number using digits, 365.
- Not Sure:
- Now I remember another term on that list! Word form just means that the digits are written in words, three hundred sixty-five.
- Problem Solver:
- There's another problem-solving strategy that can help us. Find a pattern. That way you don't have to remember so many rules. There is a pattern in reading and writing larger numbers, and it has something to do with knowing the periods.
- Remembers Rules:
- There's a rule about that: Read the number in each period and say the name of each period. A period is a group of three places in a large number. If you can read three-digit numbers, and you know the names of the periods, reading big numbers is easy. We need this rule on our study notes.
- Not Sure:
- I guess I need to get a better picture of the periods in my head.
- Problem Solver:
- Okay. Let's go back to the place value chart.
