00:00:02.760 --> 00:00:12.060
Jennifer and Ethan are skip counting by fives: 36, 41, 46, 51.
00:00:13.050 --> 00:00:15.950
Which two numbers should Ethan say next?
00:00:18.080 --> 00:00:22.610
We can record the numbers in the sequence in a tens and ones chart.
00:00:24.040 --> 00:00:32.280
If we look at the ones digit, we can see a pattern: six, one, six, one.
00:00:33.540 --> 00:00:40.440
This is because we are skip counting by fives; the numbers are increasing by five each time.
00:00:42.050 --> 00:00:44.400
One plus five is six.
00:00:46.370 --> 00:00:50.040
51 plus five is 56.
00:00:51.310 --> 00:00:56.720
If we add five to 56, we get 61.
00:00:57.920 --> 00:01:03.280
The two numbers that Ethan should say next are 56 and 61.
