Cynthia Lanius' Lesson: Polyominoes
Cynthia Lanius' Lesson: Polyominoes
Description:
This Illuminations web resource activity helps students to make connections between geometry and algebra (curve-fitting), assigning variables, making predictions, writing formulas, and graphing perimeter. First students explore polyominoes which are figures formed of congruent squares placed so that the squares share a side. Then students are asked to find out how many different pentaminoes there are by drawing them on square grid paper. Students are also asked to draw as many different hexominoes as they can. Next, the students try to create a system of polyominoes with equilateral triangles rather than squares. Further, students investigate the perimeter of polyominoes and try to find patterns so they can predict what the perimeter of other polyominoes will be. In addition, students are required to make a table representing the perimeters, complete the table, and graph the ordered pairs as points on a coordinate plane. Students are also given challenge problems to further the investigation.
