10 Times Table
00:00:06.600 --> 00:00:17.000
In this video, we will learn how to multiply objects by 10 using objects or arrays to help us understand how multiplying by 10 works.
00:00:19.480 --> 00:00:21.080
One times 10 is 10.
00:00:22.440 --> 00:00:25.640
This is the same as saying one group of 10.
00:00:27.960 --> 00:00:33.680
Two times 10 is 20, or two groups of 10 makes 20.
00:00:36.240 --> 00:00:38.360
Three times 10 is 30.
00:00:40.560 --> 00:00:42.080
Four tens are 40.
00:00:43.920 --> 00:00:46.080
Five tens are 50.
00:00:47.160 --> 00:00:48.960
Six tens are 60.
00:00:50.600 --> 00:00:52.880
Seven tens are 70.
00:00:54.200 --> 00:00:55.560
Eight tens are 80.
00:00:57.280 --> 00:00:58.880
Nine tens are 90.
00:01:00.360 --> 00:01:04.320
And 10 multiplied by 10 is 100.
00:01:06.040 --> 00:01:11.320
Let’s look at some example questions which help us to practice multiplying by 10.
00:01:13.040 --> 00:01:17.520
In this question, Daniel bought three boxes of pencils.
00:01:18.440 --> 00:01:20.840
Each box has 10 pencils.
00:01:21.800 --> 00:01:24.880
How many pencils does Daniel have in total?
00:01:26.880 --> 00:01:31.600
The question tells us that Daniel has three boxes of 10 pencils.
00:01:33.480 --> 00:01:39.720
So to find out how many he has in total, we need to multiply three by 10.
00:01:41.840 --> 00:01:46.040
We can use three 10 rods to represent the pencils.
00:01:47.400 --> 00:01:54.920
Now we can count in tens: 10, 20, 30.
00:01:56.840 --> 00:02:02.760
Daniel has 30 pencils all together because three times 10 is 30.
00:02:05.360 --> 00:02:13.120
In this example, the question tells us a boy has seven boxes of fish and a girl has one box of fish.
00:02:13.800 --> 00:02:15.600
Each box has 10 fish.
00:02:16.160 --> 00:02:18.480
How many fish do they have altogether?
00:02:20.160 --> 00:02:24.240
So we know that the boy has seven boxes and the girl has one box.
00:02:25.560 --> 00:02:28.440
Altogether, that makes eight boxes.
00:02:29.960 --> 00:02:34.240
The question also tells us that each box has 10 fish.
00:02:35.400 --> 00:02:43.080
So to find out how many fish they have altogether, we need to multiply eight by 10.
00:02:43.320 --> 00:02:48.320
One way we can do this is to use the boxes to help us count in tens.
00:02:50.320 --> 00:03:08.960
Let’s count in tens: 10, 20, 30, 40, 50, 60, 70, 80.
00:03:10.360 --> 00:03:13.080
Eight multiplied by 10 is 80.
00:03:14.800 --> 00:03:22.040
In this video, we’ve learned how to multiply by 10 using objects or arrays to help us solve problems.
