Measurement 6: Perimeter and Area

We already learned the formulas and math of perimeter and area in math, so for perimeter and area in science, I wanted it to be all hands-on. Here is the page in our Measurement Packet:

Perimeter and Area

There is nothing super special about this activity, except it takes perimeter and area off the paper and lets the kids experience it for themselves.

The really fun activity we did with perimeter and area was Perimeter and Area with Google Earth! If you don’t have Google Earth on your computers you can download it free here. If you haven’t used Google Earth with your kids before, then you will want to give your students some time to just play with it the first time, it is so fun! Since we have already used Google Earth, we jumped right into using the Ruler tool to find the Perimeter and Area of very large things!

Google Earth-perimeter and area

The activity starts out with typing in the address of your school and measuring the length and width using the ruler tool on Google Earth:

Google Earth: Ruler

The kids loved that they could switch between units and figure out how many centimeters or miles our building is!

Next, we flew to the Pentagon:

Google Earth: Pentagon

We used the “Path” tool to find the perimeter of the Pentagon. Since we are not quite ready to find the area of a pentagon, we just found the perimeter of this one, but if you have older students you could definitely have them find the area too!

Google Earth: Lake Superior

We also used the path tool to find the perimeter of a very large, irregular shaped location: Lake Superior. Some kids were extremely particular using 20 or more points to make a perfect perimeter, others were more like me… (By the way, Lake Superior is about 63 million inches around!)

The rest of the activity has the kids measure the perimeter of the United States, Colorado, and a state of their choice. This turned out to be a very successful activity, and the kids had to have a very solid understanding of perimeter and area to complete each task.
