00:00:01.900 --> 00:00:06.490
Count in 100s and 10s to write the missing numbers.
00:00:06.890 --> 00:00:16.820
100, 200, 300, what, 410, what and what.
00:00:18.000 --> 00:00:20.930
In this question, we’re shown some place-value blocks.
00:00:22.030 --> 00:00:24.860
And we need to count those in 100s.
00:00:25.780 --> 00:00:33.200
100, 200, 300, 400.
00:00:34.020 --> 00:00:36.980
We know the first missing number is 400.
00:00:38.210 --> 00:00:49.190
Now we need to continue counting in 10s: 410, 420, 430.
00:00:50.370 --> 00:00:59.420
100, 200, 300, 400, 410, 420, 430.
00:01:00.620 --> 00:01:07.310
The missing numbers are 400, 420, and 430.
