00:00:01.690 --> 00:00:06.210
Victoria started dividing this rectangle into equal squares.
00:00:07.580 --> 00:00:12.680
Which addition sentence tells you how many squares there will be when she is finished?
00:00:14.680 --> 00:00:18.190
We can see that Victoria has a green rectangle shape.
00:00:18.890 --> 00:00:24.630
And on the rectangle, she started to draw lines to divide it into equal squares.
00:00:25.350 --> 00:00:30.880
Across the top of the rectangle, Victoria has drawn a row of five squares.
00:00:31.660 --> 00:00:33.970
This goes from one side of the rectangle to the other.
00:00:34.900 --> 00:00:37.460
So, we could say that rectangle is five squares long.
00:00:38.570 --> 00:00:43.180
But how many rows of five squares can Victoria fit within this rectangle?
00:00:43.760 --> 00:00:47.120
We can see that she’s also completed a column of squares.
00:00:47.570 --> 00:00:49.610
And there are two squares in that column.
00:00:50.410 --> 00:00:59.100
This means that when she’s finished dividing the rectangle into equal squares, there should be two rows, and each row should contain five squares.
00:00:59.870 --> 00:01:04.610
And we can use this to work out how many square there should be when she’s finished.
00:01:06.050 --> 00:01:07.980
The first row will have five squares.
00:01:08.530 --> 00:01:10.600
And the second row will have five squares.
00:01:10.990 --> 00:01:15.690
Five plus five equals 10 squares altogether.
00:01:16.410 --> 00:01:20.860
And to check our answer, we could draw in the rest of Victoria’s lines.
00:01:23.780 --> 00:01:27.980
We can see that she divides the whole rectangle into equal squares.
00:01:28.360 --> 00:01:30.820
She’ll create two rows of five.
00:01:31.460 --> 00:01:38.760
The addition sentence that tells us how many squares there’ll be when she’s finished is five plus five equals 10.
00:01:40.060 --> 00:01:43.350
The rectangle has been split into 10 equal squares.
