Yarn Balloon Eggs

The next peer taught lesson was one where we created yarn balloon eggs. I have seen this on Pinterest many times and was very excited to be able to try this. To introduce this lesson, they used the book Sir Cumference and the Dragon of Pi. I thought this was a great way to introduce this lesson because one of the things we had to focus on once we started the project was wrapping yarn around the circumference of the balloon. 

To start the project we had to pick what color yarn we wanted to use. I decided to grab the blue and brown yarn because it was very neutral. We then had to blow up a balloon. We got a mixture of 60% water and 40% glue in which we were supposed to drag our yarn through and then wrap the yarn around the balloon. We were reminded to focus on the circumference many times throughout the lesson. 

Once we believed a majority of the balloon was covered, we placed the balloon in a cup to dry. Once the yarn was dry, the peer teachers popped the balloon. The glue on the yarn allowed it to keep its shape so the teachers could create their bulletin board display shown below. 

As an extension activity, students could take their yarn eggs to math class and try to figure out the actual circumference of their egg. They could also bring other items to class to measure the circumference of those things too. To incorporate the yarn again, they could wrap the yarn around the different items and then measure how long the yarn was to help them see the visual of circumference.
