An array of shaded and blank counters is shown.At the top of the image are 3 rows of 6 shaded counters. Below the bottom row of shaded counters are 3 dots in a vertical line. Below the 3 dots is another row of 6 shaded counters. To the right of the last row of shaded counters is a row of 4 blank counters. To the left of the array of shaded counters is a large right-facing bracket that frames the counters and dots. A label to the left of the bracket reads "x rows”.
