Use the array to fill in all the missing numbers in these related facts.
00:00:08.430 --> 00:00:12.110
Let’s start with the first fact, six times four.
00:00:13.580 --> 00:00:19.040
This array has six columns and four rows.
00:00:19.980 --> 00:00:26.350
If we count all the blocks, we’ll be able to find out what six times four equals.
00:00:27.520 --> 00:00:49.510
One, two, three, four, five, six, seven, eight, nine, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24.
00:00:50.680 --> 00:00:57.340
24 squares in the array tell us that six times four equals 24.
00:00:59.120 --> 00:01:05.620
And likewise for the next problem, four times six equals 24.
00:01:07.090 --> 00:01:09.670
Our division problem is a little bit different.
00:01:11.250 --> 00:01:14.610
It says 24 divided by six.
00:01:15.600 --> 00:01:21.720
We need to use our array, the 24 squares, and divide them into six groups.
00:01:22.950 --> 00:01:26.340
We can do that by breaking up the six columns.
00:01:27.920 --> 00:01:35.300
If we consider each column a group, how many squares are in each column?
00:01:37.060 --> 00:01:40.460
Each column has four squares.
00:01:41.520 --> 00:01:47.840
24 divided into six groups gives us four in each group.
00:01:49.280 --> 00:01:54.400
Our last problem says blank divided by six equals four.
00:01:54.720 --> 00:01:59.010
What number if you divide that into six gives you four?
00:02:00.550 --> 00:02:04.870
We’ve already found that 24 divided by six equals four.
00:02:06.760 --> 00:02:12.670
An array can help us visualize multiplication and division problems like these.
