00:00:00.600 --> 00:00:02.760
What is the number?
00:00:04.000 --> 00:00:07.760
We can use a place value chart to help.
00:00:08.880 --> 00:00:15.680
First, let’s count the ones bricks: one, two, three, four, five.
00:00:16.360 --> 00:00:20.000
So we can write the digit five in the ones column.
00:00:21.120 --> 00:00:27.920
Now let’s count the tens blocks: one, two, three, four.
00:00:28.800 --> 00:00:33.160
So we can write the four digit in the tens column.
00:00:34.200 --> 00:00:37.520
We have four tens and five ones.
00:00:38.440 --> 00:00:41.720
The number is 45.
