1 00:00:00,750 --> 00:00:03,229 Now we're going to learn about centuries. 2 00:00:04,650 --> 00:00:06,070 What is a century? 3 00:00:07,129 --> 00:00:09,830 Well, it's 100 years. 4 00:00:10,849 --> 00:00:14,789 We use centuries to talk about a period of time. 5 00:00:15,849 --> 00:00:19,710 In the previous video, we looked at how to say years. 6 00:00:19,710 --> 00:00:30,030 For example, 1423, 1605, 731, 2008. 7 00:00:31,390 --> 00:00:34,109 Now we're going to learn how to talk about centuries. 8 00:00:35,789 --> 00:00:42,509 Do you know what century we're in now? Well we're in the 21st century. Do you know why? 9 00:00:43,869 --> 00:00:55,179 Let's have a look and see if we can understand. When you are born you are zero years old 10 00:00:56,539 --> 00:01:02,460 but during the next 12 months we say you are in your first year of life. 11 00:01:02,460 --> 00:01:11,459 Then you have your first birthday. You are now one year old, because you have lived for one year. 12 00:01:11,459 --> 00:01:16,459 But you are now starting your second year of life. 13 00:01:16,459 --> 00:01:28,459 When you have your next birthday, you are two years old, but you are starting your third year of life, and so on. 14 00:01:28,459 --> 00:01:42,780 Do you know what year of life are you in now? Have a think. Well, it's the same thing for centuries. 15 00:01:43,799 --> 00:01:50,939 As we learnt before, a century is a hundred years. So let's have a look at this graph below. 16 00:01:52,480 --> 00:02:01,200 Our calendar started with the birth of Christ. We say that was year one and it was the first century. 17 00:02:01,200 --> 00:02:11,919 so from 1 AD until 99 AD it was the first century. At the end of a hundred 18 00:02:11,919 --> 00:02:27,349 years the second century began. Can you see the pattern? Here is a table with 19 00:02:27,349 --> 00:02:38,870 years and the centuries they are in. The year 992 was in the 10th century. 1067 20 00:02:38,870 --> 00:02:55,069 in the 11th century, 1169 in the 12th century, 1299 in the 13th century, 1327 in the 14th 21 00:02:55,069 --> 00:03:11,500 century, 1411 in the 15th century, 1506 in the 16th century and 1600 in the 17th century. 22 00:03:11,500 --> 00:03:23,669 So can you see the pattern here? The 12th century is from 1100 to 1199. When you read 23 00:03:23,669 --> 00:03:32,729 that Columbus discovered America in 1492, you can say America was discovered in the 24 00:03:32,729 --> 00:03:39,909 15th century. Here is another table with some years and 25 00:03:39,909 --> 00:03:51,729 the centuries they are in. 1134 in the 12th century, 1367 in the 14th 26 00:03:51,729 --> 00:04:10,469 892 in the 9th century, 1999 in the 20th century, 1727 in the 18th century, 411 in the 5th century, 27 00:04:10,469 --> 00:04:22,439 1406 in the 15th century and the year 2000 in the 21st century and now it's 28 00:04:22,439 --> 00:04:31,620 your turn I want you to write and say the centuries for each year so for 29 00:04:31,620 --> 00:04:43,050 example the year 1287 is in the 13th century have a look and try and say 30 00:04:43,050 --> 00:05:01,040 them. How are we doing? Do we know? What year is 478? It's in the 5th century. 31 00:05:01,040 --> 00:05:11,720 Fantastic. And what about 1444? Yes, that's right, the 15th century. So carry 32 00:05:11,720 --> 00:05:16,060 on and do your best.
