The perimeter of polyominoes is another interesting investigation. Complete the following table on the perimeter of the polyominoes.
No. of Squares Perimeter 1 2 3 & Think you see a pattern here? So can you predict what the perimeter of the tetrominoes (4 squares) is?
No. of Squares  Perimeter 

4 

















Was your prediction correct? Did you predict that there would be two different perimeters? (?!) A word of caution: be careful with predictions. Sometimes a function will vary from the particular pattern it begins with.Copyright 19982004 Cynthia Lanius URL http://math.rice.edu/~lanius/Lessons/Polys/poly6.htmlLet's make another table and label the perimeters minimum and maximum. After you complete the table, graph the ordered pairs as points on a coordinate plane. Make two graphs, letting x represent No. of Squares and y represent both the minimum and maximum perimeters.
No. of Squares Minimum Perimeter Maximum Perimeter 1 2 3 4 5 6 7 8 9 Challenge Problem: Find the curve of best fit for both the long and short perimeters.
