Remember to start reading the number by saying six million. Then read the next three digits as two hundred four. Then say the comma name of thousand. So it would read, two hundred four thousand. Then finish the number by reading the digits 7-1-1 as seven hundred eleven. When you put it all together it sounds like…
six million, two hundred four thousand, seven hundred eleven

Take out a sheet of paper and write all you can remember about how to read and write large numbers without going back to look at the videos or text. See how much you can remember from what you watched and read. Challenge your brain to think deeply about what you know and write it down on your paper. It doesn't have to be fancy or spelled correctly. It can just be written as bullet points, but really focus on writing down what you know before moving on in this book.
