00:00:02.400 --> 00:00:06.160
State whether the answer to the sum is even or odd.
00:00:07.010 --> 00:00:08.930
Seven plus seven.
00:00:10.900 --> 00:00:19.900
We have to find the sum of seven plus seven and then say whether the sum is odd or even.
00:00:21.770 --> 00:00:24.340
Let’s model seven plus seven.
00:00:26.060 --> 00:00:28.410
Here we have seven squares.
00:00:28.920 --> 00:00:31.250
And we need to add seven more.
00:00:33.220 --> 00:00:37.360
Now we have two lots of seven or seven plus seven.
00:00:39.360 --> 00:00:44.660
To find the sum of seven plus seven, we need to add both groups together.
00:00:46.370 --> 00:00:50.150
We have to decide if this sum is an even or odd number.
00:00:50.950 --> 00:00:55.100
And we know that even numbers are divisible by two.
00:00:55.650 --> 00:00:59.260
That means we can divide even numbers by two.
00:01:00.940 --> 00:01:07.350
So let’s find the sum of seven plus seven by counting the squares in twos.
00:01:08.380 --> 00:01:12.340
This will help us decide if the number is odd or even.
00:01:13.820 --> 00:01:15.620
One group of two is two.
00:01:16.980 --> 00:01:18.690
Two times two is four.
00:01:20.200 --> 00:01:22.000
Three twos make six.
00:01:23.720 --> 00:01:25.630
Four twos make eight.
00:01:27.140 --> 00:01:28.670
Five twos make 10.
00:01:30.490 --> 00:01:32.340
Six twos make 12.
00:01:33.940 --> 00:01:36.260
And seven twos make 14.
00:01:37.700 --> 00:01:41.050
The sum of seven plus seven is 14.
00:01:42.300 --> 00:01:49.010
And we know that 14 is an even number because it’s divisible by two.
00:01:50.590 --> 00:01:54.830
We divided our 14 squares into groups of two.
00:01:56.800 --> 00:02:00.410
There were seven groups of two, which makes 14.
00:02:02.120 --> 00:02:06.440
The sum of seven plus seven is an even number.
