00:00:02.990 --> 00:00:05.900
Which calculation describes this model?
00:00:07.190 --> 00:00:09.550
Two groups of four equals eight.
00:00:10.470 --> 00:00:13.210
Four groups of two equals eight.
00:00:14.280 --> 00:00:17.070
Six groups of two equals eight.
00:00:17.880 --> 00:00:20.960
Or two groups of six equals eight.
00:00:22.500 --> 00:00:25.220
The model shows two groups.
00:00:26.050 --> 00:00:30.630
So, we can cross out the choices of four groups and six groups.
00:00:31.590 --> 00:00:34.300
Each group contains four counters.
00:00:34.740 --> 00:00:37.250
So, there are two groups of four.
00:00:38.450 --> 00:00:44.840
The calculation which describes this model is two groups of four equals eight.
