00:00:01.100 --> 00:00:04.910
We know that seven plus three equals 10.
00:00:07.960 --> 00:00:10.220
What other facts do we know?
00:00:10.750 --> 00:00:12.240
Find the missing numbers.
00:00:14.390 --> 00:00:20.800
Starting on the left, we have the number sentence 10 minus seven equals what.
00:00:22.780 --> 00:00:32.520
If we look at the first set of blocks we were given, we see that the yellow represents three because three plus seven equals 10.
00:00:33.250 --> 00:00:40.100
So if we have 10 and we take away seven, we will be left with three.
00:00:42.280 --> 00:00:48.650
Our second number sentence says 10 minus how many equals three.
00:00:50.620 --> 00:00:54.270
Again, we can look at the blocks that we started with.
00:00:54.920 --> 00:01:01.380
We know that there are seven green blocks and that seven plus three equals 10.
00:01:03.340 --> 00:01:09.480
If we have 10 and take away seven, there will be three remaining.
00:01:11.620 --> 00:01:16.310
We know that 10 minus seven equals three.
