You will be looking for similar polygons. So what are the two properties that make polygons similar to each other?
Graph the six shapes, using one rubber band for each polygon. After your graph the shape give each polygon name the figure. Each shape should make a different shape.
Based on the criteria for similar polygons, tell which of the shapes on the geoboard are similar to their corresponding commercial pattern block model and which of the shapes are not similar. Be able to use mathematical reasoning to tell how you determined your answer.
In addition you could ask students to find the perimeter and area of each graph polygon.
Notice that the geoboard has 100 square units. Find the area of each polygon on the geoboard. Be ready to justify your answer.
The geoboard is 10 units by 10 units. Find the perimeter of each polygon on the geoboard.
