We make stairs as shown above using 1 cm. square blocks.
(1). As the number of steps increases (1, 2, 3, …), try to find out
how the length around the outside (perimeter)
changes.

(2). When there are 8 steps, how many centimeters
will the length be around the outside?
(3). Look for a
pattern and see if you can make a generalization.
(4). Write math problems you learned in the United Sates that
is similar to this problem.
