Video 1 - Say and Write Whole Numbers

I can say and write whole numbers up to one million.<br> You have learned that written numbers are made of digits. Some numbers have less digits and some numbers have more. First of all if you know, when we look at whole numbers, the more digits there are the bigger the number. And the less digits there are, the smaller the number. This is for whole numbers. For instance, thirty is bigger than three. Thirty has two digits which is more than three which only has one digit. And three hundred is bigger than thirty. Three digits are more than two. Second of all, digits have different values or worth depending on where they sit in a number. In short, how we say and write numbers depend on two things. One, how many digits are in a number, and two, where those digits sit in a number. Today, I want to teach you how to say and write numbers up to the millions.<br> Our number are built in groups of three digits. And each group of three digits has places for ones, tens, and hundreds. Let’s take the number five, or five ones. We can write the number and say the number five easily because it is only one digit. And that first digit place is ones. Now look at the number fifty-five. You know it has five tens and five ones. You can say and write the number easily because it is only two digits – tens and ones. We say and write fifty-five. Now, look at the number five hundred fifty-five. You know it as five hundreds, five tens, and five ones. You can say and write the number easily because it is only three digits – hundreds, tens, and ones. We say and write five hundred fifty-five. All three of these stitches together are the singles group. It represents five hundred fifty-five single things.<br> Now, the next group of digits works the same way, except that you know the number gets bigger. Remember, more digits equals bigger number. This next group of three digits are the thousands. Separate this group from the singles group with a comma. It also begins with the ones, then the tens, and you guessed it – the hundreds. Let’s look at this number: Five thousand five hundred fifty-five. I separate the thousands group from the singles group with a comma. And it is bigger than five hundred fifty-five because it has more digits. Let’s look at fifty-five thousand five hundred fifty-five. You’re write it like this. And of course, it is still bigger than the last number. Can you guess how we would write five hundred fifty-five thousand five hundred fifty-five? Can you see it in your mind? Can you see the comma that separates the singles group from the thousands group? You got it. There it is – 555,555.<br> Now, on to our next group of digits. It is the millions group. And these numbers are also in, you guessed it – ones, tens, and hundreds – just like the last two groups. Can you picture in your mind where to out the comma that separates the millions group of three digits from the thousands group of three digits? I bet you can. There it is – 555,555,555. But lucky you we can keep it simple. You only need to know how to read and write numbers up to one million.<br> Let’s practice. Say this number with me: three. Say this number with me: thirty-three. How about this number? Ready? Thirty-three thousand three hundred thirty-three. Remember? Don’t forget to use that comma. It helps you distinguish the thousands group from the singles group. And that’s where you say the word thousand.<br> Okay, pick up your white boards and let’s practice writing the numbers as I say them. Go ahead and check your numbers with your neighbor to check yourself. If you have written down different numbers, discuss it with your neighbor. Forty-five. Next, six hundred thirty-eight. Okay? Ready for a big one? Think about where to put that comma when you hear the word thousands. Four hundred sixty-nine thousand two hundred fifty-six. Did you hear the word thousand? That’s your clue where to put the commas separating the thousands group from the singles group.<br> Our number are written and spoken in groups of three digits. Each group of three has the ones, tens, and hundreds. And we have the singles group, then the thousands group, and even the millions group. Today, you will practice with a partner using the coach and player practice. Each of you will practice writing and saying different numbers, and each of you will be coaching your partners to success.
