An array can be used to model equal
groups of objects. Which of the following is not an
array?
We’re shown five different groups
of objects. One of these groups is not an
array, which means all the other groups are arrays. Which of these groups is not an
array? An array is when objects are
grouped together in equal rows, or columns. This is an array. This array shows three columns, and
each column contains three dots. This is an array. We can group the dots in the second
picture into three rows of two, so we know this picture is also an array.
This picture shows one row of four
dots. It’s an array. This picture shows three rows, but
the rows are not equal. The first row contains four dots,
but the second row only contains three, and the third row contains four dots. If the rows are not equal, this is
not an array. So, this is the model which is not
an array.
