This is a document that includes descriptions for the three types of symbiotic relationships that are found in ecosystems as well as practice examples. I printed this document two to a page and then copied it front and back to create a booklet foldable to go in my student's interactive notebook. We read through the descriptions together and then students completed the practice examples by themselves. We then review their answers. I then had my students complete a reflection (or left side page) over these relationships in their INB.
