00:00:00.910 --> 00:00:02.620
There are two baskets.
00:00:02.890 --> 00:00:05.780
Each basket has 11 marbles inside.
00:00:06.390 --> 00:00:08.490
How many marbles are there altogether?
00:00:09.980 --> 00:00:14.560
When we’re solving word problems, we always highlight the key numbers to begin with.
00:00:15.440 --> 00:00:17.350
We know there are two baskets.
00:00:18.060 --> 00:00:20.510
And each basket has 11 marbles.
00:00:21.350 --> 00:00:24.550
And the question asks us how many marbles altogether.
00:00:25.700 --> 00:00:31.440
We can draw a quick sketch or model to help us visualize the problem or picture it in our head.
00:00:32.740 --> 00:00:38.000
So we have two baskets, each with 11 marbles inside.
00:00:39.070 --> 00:00:42.060
We could say there are two groups of 11.
00:00:44.080 --> 00:00:45.970
So now we can record our equation.
00:00:47.200 --> 00:00:50.600
We know that groups of is the same as saying multiply.
00:00:50.980 --> 00:00:58.600
So our equation is two multiplied by 11, which is the same as 11 multiplied by two.
00:01:00.040 --> 00:01:04.320
We can calculate the answer using a place value chart to help us.
00:01:05.500 --> 00:01:10.930
Let’s start with the biggest number 11 which has one 10 and a one.
00:01:12.100 --> 00:01:14.230
And we’re multiplying by two.
00:01:15.300 --> 00:01:17.020
Let’s start in the ones column.
00:01:17.570 --> 00:01:20.120
We have two multiplied by one.
00:01:20.690 --> 00:01:24.240
Two times one, this makes two.
00:01:25.930 --> 00:01:31.720
Moving over into the tens column, we have to multiply this digit by two also.
00:01:32.660 --> 00:01:36.500
One multiplied by two equals two.
00:01:37.900 --> 00:01:40.850
There are 22 marbles altogether.
00:01:42.150 --> 00:01:45.590
We multiplied 11 by two to find the answer.
