00:00:00.560 --> 00:00:02.520
Fill in the blanks in this multiplication table.
00:00:03.480 --> 00:00:11.600
Now looking at this multiplication table, the arrow shows us that we’re supposed to read it from left to right.
00:00:12.320 --> 00:00:14.440
And we’ve got two separate rows to consider.
00:00:14.760 --> 00:00:26.440
If we look at the first row to begin with, we can see that we start with four, we multiply it by something, and we get an answer of 24.
00:00:27.120 --> 00:00:35.320
We could write this as the number sentence four multiplied by something equals 24.
00:00:35.840 --> 00:00:38.400
The second row is a little bit more complicated.
00:00:38.600 --> 00:00:53.080
It shows us that we start with seven, we multiply it by the same unknown amount as the first multiplication, and we get an answer that we don’t know yet either.
00:00:53.880 --> 00:01:02.040
We can record that as the number sentence seven multiplied by something equals something.
00:01:02.840 --> 00:01:06.920
Now can you see the order with which we need to solve the problem?
00:01:07.600 --> 00:01:12.920
First of all, we need to use the first row to find the number that we multiply by.
00:01:13.520 --> 00:01:19.400
And once we know that, we can find the missing number in the second row.
00:01:20.360 --> 00:01:27.840
So our first question is what do we multiply four by to get 24.
00:01:28.360 --> 00:01:41.120
Well let’s count in fours to find out: four, eight, 12, 16, 20, and 24.
00:01:41.760 --> 00:01:45.520
So there are six fours in 24.
00:01:45.960 --> 00:01:50.720
So we know that our multiplication table is a times six table.
00:01:51.240 --> 00:01:57.600
All the numbers on the left are multiplied by six to get the numbers on the right.
00:01:58.480 --> 00:02:05.520
Now that we know that we need to multiply by six, the second missing number becomes a lot easier to solve.
00:02:06.120 --> 00:02:13.680
So we know that the number seven is multiplied by six, and the answer will go in that bottom box of the multiplication table.
00:02:14.160 --> 00:02:16.320
So what are seven sixes?
00:02:16.880 --> 00:02:26.400
Well maybe you already know that multiplication fact to help, or we could count in sixes seven times.
00:02:26.840 --> 00:02:36.920
But another way to find the answer is to use what we worked out for the first multiplication to help us with the second.
00:02:37.680 --> 00:02:46.560
Let’s try that method rather than counting seven lots of sixes, which might take a while.
00:02:47.400 --> 00:02:52.360
Now we already know that four sixes are 24.
00:02:53.000 --> 00:02:57.680
And if we double this amount, it will give us eight sixes.
00:02:58.240 --> 00:03:07.800
Four sixes are 24, so double that is 48.
00:03:08.400 --> 00:03:12.760
So eight sixes are 48.
00:03:13.480 --> 00:03:20.800
Now that we know what eight sixes are, we can take away one lot of six to get the answer to seven sixes.
00:03:21.600 --> 00:03:26.840
48 minus one lot of six equals 42.
00:03:27.480 --> 00:03:34.280
And so the missing number, seven multiplied by six, is 42.
00:03:34.680 --> 00:03:41.600
And so the blanks in this multiplication table can be filled in with the numbers six and 42.
