Complete the pattern.
First, we have to find the
rule. The pattern begins with one pink
square. Next, there are two pink squares,
then three. What’s happening to the squares
each time? One plus one makes two. Two plus one makes three. The rule of the pattern is to add
one pink square each time. We also need to think about where
to add the pink square, on top, at the bottom, to the left, to the right. We have to add one square here, to
the right each time. So the rule of the pattern is to
add one pink square to the right each time. So to complete the pattern, we need
to add one square to the right. So we would complete the pattern
using four pink squares.
