00:00:00.760 --> 00:00:04.120
Numbers up to 10 on a Number Line.
00:00:04.920 --> 00:00:13.840
In this video, we will learn how to use number lines to model the counting sequence from zero to 10.
00:00:14.160 --> 00:00:15.720
This is a number line.
00:00:16.320 --> 00:00:20.920
It starts at zero and ends at number 10.
00:00:21.360 --> 00:00:33.120
And this is a jumping jellybean who’s going to help us learn how to count from zero to 10 on a number line.
00:00:33.800 --> 00:00:38.520
Did you remember that this number line starts at zero?
00:00:38.520 --> 00:00:41.440
So this is where we should start counting.
00:00:42.200 --> 00:00:44.840
We’re going to count from zero to 10.
00:00:45.800 --> 00:01:03.560
Zero, one, two, three, four, five, six, seven, eight, nine, 10.
00:01:04.520 --> 00:01:06.800
Here’s another number line.
00:01:06.800 --> 00:01:09.080
All of the numbers are missing though.
00:01:09.680 --> 00:01:13.800
But the numbers have been represented by counters.
00:01:14.480 --> 00:01:18.400
The first number is shown using no counters.
00:01:19.080 --> 00:01:24.440
So we can write the number zero on the first digit card.
00:01:25.400 --> 00:01:33.120
Next, we can see one counter, two, three.
00:01:34.000 --> 00:01:39.360
Did you notice we’re adding one more counter each time?
00:01:40.040 --> 00:01:49.480
Four, five, six, seven, eight, nine, 10.
00:01:50.320 --> 00:01:56.000
The number of counters increased by one each time.
00:01:56.640 --> 00:02:04.280
If we count the numbers from left to right on a number line, the numbers increase.
00:02:04.880 --> 00:02:17.840
Zero, one, two, three, four, five, six, seven, eight, nine, 10.
00:02:18.480 --> 00:02:23.680
We can use number lines for lots of things in maths.
00:02:24.240 --> 00:02:30.960
In this video, we’re going to use a number line to help us compare numbers.
00:02:31.760 --> 00:02:35.640
Let’s compare the numbers four and seven.
00:02:36.600 --> 00:02:41.680
The number four comes before number seven on the number line.
00:02:42.360 --> 00:02:46.080
Number seven comes after number four.
00:02:47.040 --> 00:02:57.200
And we know that if we start at zero and count from left to right on a number line, the numbers increase.
00:02:57.880 --> 00:02:59.600
They get larger.
00:03:00.240 --> 00:03:07.680
So we could say that four is less than seven or seven is greater than four.
00:03:08.520 --> 00:03:14.400
And we can see that seven counters are more than four counters.
00:03:15.000 --> 00:03:17.240
Seven is more than four.
00:03:17.840 --> 00:03:22.200
And four counters are less than seven counters.
00:03:22.840 --> 00:03:29.440
If a number comes after another number on a number line, it means it’s greater.
00:03:30.080 --> 00:03:37.640
And if a number comes before another number on the number line, it means it’s less.
00:03:38.600 --> 00:03:46.440
Let’s practice using number lines to help us count and compare numbers.
00:03:47.440 --> 00:03:51.560
Some numbers are missing from this number line.
00:03:52.160 --> 00:04:05.480
Zero, one, two, three, what, what, six, seven, eight, nine, 10.
00:04:06.160 --> 00:04:10.480
What number should be on the orange card?
00:04:11.280 --> 00:04:15.400
What number should be on the blue card?
00:04:16.200 --> 00:04:21.600
In this question, we have to find the missing numbers from the number line.
00:04:22.280 --> 00:04:27.640
The first missing number should be on the orange card.
00:04:28.320 --> 00:04:33.560
And the second missing number should be on the blue card.
00:04:34.480 --> 00:04:37.880
Let’s use the number line to help.
00:04:38.760 --> 00:04:46.840
The number on the orange card comes after number three on the number line.
00:04:47.400 --> 00:04:50.640
Which number comes after number three?
00:04:51.560 --> 00:04:57.160
We could draw three counters and then one more.
00:04:57.960 --> 00:05:00.320
We’ve drawn three counters.
00:05:00.320 --> 00:05:05.520
If we add one more, that will be four.
00:05:06.240 --> 00:05:09.840
One, two, three, four.
00:05:10.760 --> 00:05:22.200
The number on the orange card is number four, because four comes after three on the number line.
00:05:23.200 --> 00:05:29.000
The number on the blue card comes after number four.
00:05:29.880 --> 00:05:32.640
We have four blue counters.
00:05:33.280 --> 00:05:36.120
So now we need one more.
00:05:36.800 --> 00:05:40.480
Four and one more is five.
00:05:41.440 --> 00:05:46.280
The number that comes after number four is number five.
00:05:46.920 --> 00:05:52.600
Zero, one, two, three, four, five.
00:05:53.160 --> 00:05:59.000
The number that should be on the orange card is number four.
00:05:59.480 --> 00:06:05.040
And the number that should be on the blue card is number five.
00:06:05.520 --> 00:06:10.600
The missing numbers are numbers four and five.
00:06:11.960 --> 00:06:15.720
Which is less, one or four?
00:06:16.480 --> 00:06:24.680
We’re being asked to use a number line to compare two numbers, the number one and the number four.
00:06:25.560 --> 00:06:27.800
Which of these two numbers is less?
00:06:28.640 --> 00:06:33.560
Number one comes before number four on the number line.
00:06:34.240 --> 00:06:38.520
One, two, three, four.
00:06:39.520 --> 00:06:45.360
When we count from left to right on the number line, the numbers increase.
00:06:45.920 --> 00:06:50.160
We start with the number with the least value at the beginning of the number line.
00:06:50.640 --> 00:06:53.800
And the value of the numbers increases.
00:06:54.480 --> 00:06:58.920
Four is worth more than one.
00:06:59.560 --> 00:07:04.000
One is worth less than four.
00:07:04.880 --> 00:07:08.640
One counter is less than four.
00:07:09.280 --> 00:07:15.480
The answer to the question “Which is less, one or four?” is one.
00:07:15.960 --> 00:07:18.520
One is less than four.
00:07:19.600 --> 00:07:23.280
What is one more than six?
00:07:24.360 --> 00:07:27.360
Here’s the number six on the number line.
00:07:28.040 --> 00:07:32.440
We have to find the number which is one more than six.
00:07:33.360 --> 00:07:39.200
When we count from left to right on a number line, the numbers increase.
00:07:40.080 --> 00:07:49.920
Zero, one, two, three, four, five, six, seven.
00:07:50.560 --> 00:07:55.480
The number which is one more than six is seven.
00:07:56.280 --> 00:08:01.320
Seven is after number six on the number line.
00:08:01.920 --> 00:08:07.360
The number which is one more than six is seven.
00:08:08.400 --> 00:08:10.480
Which number line is correct?
00:08:10.960 --> 00:08:22.160
Four, five, six, one, three, nine, seven, two, zero, eight, 10.
00:08:23.080 --> 00:08:33.960
Zero, one, two, three, four, five, six, seven, eight, nine, 10.
00:08:34.160 --> 00:08:44.840
Or zero, one, two, five, nine, three, four, eight, seven, six, 10.
00:08:45.640 --> 00:08:49.320
Which of these three number lines is correct?
00:08:50.160 --> 00:08:54.440
Maybe you followed the numbers as you were listening to the question.
00:08:55.160 --> 00:08:56.960
Did one sound correct?
00:08:57.960 --> 00:09:01.760
We know the first number line is not correct.
00:09:02.240 --> 00:09:06.720
It begins with a number four and ends with a number 10.
00:09:08.000 --> 00:09:15.640
The second and third number lines both begin with a zero and both end with 10.
00:09:16.240 --> 00:09:18.040
Which of these is correct?
00:09:18.640 --> 00:09:19.920
Let’s count.
00:09:20.560 --> 00:09:35.040
Zero, one, two, three, four, five, six, seven, eight, nine, 10.
00:09:35.640 --> 00:09:37.880
This number line is correct.
00:09:38.400 --> 00:09:41.080
Let’s check the third number line.
00:09:41.560 --> 00:09:46.000
Zero, one, two, three.
00:09:46.680 --> 00:09:49.240
Oh, it says number five.
00:09:49.680 --> 00:09:51.080
That’s not correct.
00:09:51.720 --> 00:09:56.920
The number line in the middle is correct.
00:09:57.400 --> 00:10:08.800
Zero, one, two, three, four, five, six, seven, eight, nine, 10.
00:10:09.960 --> 00:10:12.240
What have we learned in this video?
00:10:12.760 --> 00:10:18.920
We’ve learned that we can count from zero to 10 on a number line.
00:10:19.520 --> 00:10:25.680
We can use number lines to help us compare numbers.
00:10:26.200 --> 00:10:36.200
And we can use a number line to find one more or one less than a number.
