What Will You Make?
Using a toilet paper roll and common art supplies, make your own friendly octopus.
What Will You Learn?
Campers will practice informal and formal measurement math skills. Younger campers will benefit from working with scissors and developing fine motor skills.
Make Your Octopus
Cut Construction Paper
Mark a line on the tube. Make a mark on the opposite side as well. Place the tube against the paper, lining up your marks with the top edge of the paper. Line up the left edge of the tube with the left edge of the paper. Mark the right edge of the tube on the paper. Slowly roll the tube, marking the right edge of the tube on the paper several times as you go. When the marks on the inside of tube hits the paper again, make a vertical mark on the paper. Use the ruler to draw lines, taking care to add 1/4 in (6 mm) to the length so that it overlaps when the tube is wrapped. Your piece will be approximately 6 inches long by about 4 1/2 inches wide, depending on your tube.
Cut the Tentacles
If desired, wrap a rubber band around the tube, about 2/3 from the bottom of the tube, about 3 inches form the bottom. Otherwise, use your ruler to measure from the bottom and mark several points to create a line around the circumference of the tube. This demarks the head of the octopus from the body. Cut 8 tentacles, each about 3/4″ wide.

Measurement and Data
This fun art project also gives campers the opportunity to define measurement terms such as length and width while using an informal method of measuring the paper. Of course, if you want campers to practice with rulers, you can have them measure the length of the tube with a ruler to determine how much paper is needed. Use dressmakers measuring tape to determine the width around the tube.
Older students can calculate the circumference of the tube by measuring the diameter. You can even have them take formal measurements first, make predictions for length and width, and then use the informal measurement method shown to test their predictions.Â
And of course, it’s an opportunity to practice the old adage, “Measure twice. Cut once.”
