🧮 Place Value Chart Maker: Digits, Values and Expanded Form

How to use it

1. 1. Type a number

   Enter a whole number up to 999,999,999 using digits only. The chart is already showing a sample number, so you can see how it works straight away.

2. 2. Read the columns

   Press Show the chart. Every digit sits in its column, from ones on the right to hundred millions on the left, and empty columns are left blank.

3. 3. Check the values

   The row underneath gives the value of each digit, so a 3 in the hundreds column is shown as 300. A zero digit has a value of 0, which helps with numbers like 5,007.

4. 4. Practise with random numbers

   Choose how many digits you want and press Random number. Cover the answers on the class screen, ask the class to say each value, then reveal the chart.

Ideas for class and home

• Expanded form warm-up

  Put a random four-digit number on the screen and ask the class to write its expanded form on mini whiteboards before you press the button to check.

• The role of zero

  Type numbers such as 40,305 and 700,020. Children see that zero holds a place, and that the digit next to it keeps its own value.

• Reading big numbers

  Use nine-digit numbers to practise reading in groups: millions, thousands and ones. The column names make the groups easy to spot.

• Compare and order

  Generate two random numbers with the same number of digits. Children compare the leftmost column first, which shows why the highest place decides which number is bigger.
