A box of crayons has two rows.
00:00:03.670 --> 00:00:06.130
There are seven crayons in each row.
00:00:08.010 --> 00:00:12.580
Noah has drawn this model to show the total number of crayons.
00:00:13.970 --> 00:00:20.180
Which of the following equations would he need to solve to find the number of crayons in the box?
00:00:21.270 --> 00:00:30.510
Two multiplied by seven, two plus seven, seven multiplied by seven, or two plus two?
00:00:33.740 --> 00:00:36.250
How many crayons are in the box?
00:00:37.590 --> 00:00:44.870
So our model shows that there are two rows: one, two.
00:00:47.820 --> 00:01:02.440
And there are seven crayons in each row: one, two, three, four, five, six, and seven.
00:01:04.250 --> 00:01:09.790
So we have two rows of seven, which is the same as saying two times seven.
00:01:12.610 --> 00:01:20.530
And the first part of our question asked us which of the following equations would Noah need to solve to find the number of crayons in the box.
00:01:21.050 --> 00:01:27.300
So from our working out, we can see that the answer would be two times seven.
00:01:29.120 --> 00:01:33.740
And the second part of the question asks how many crayons there are in the box.
00:01:35.020 --> 00:01:40.350
To work out the answer to two times seven, we could count in twos.
00:01:41.740 --> 00:01:44.550
And we would need to count seven times.
00:01:45.580 --> 00:01:59.180
So letâ€™s count together: two, four, six, eight, 10, 12, and 14.
00:02:00.670 --> 00:02:03.440
There are 14 crayons in the box.
