The first thing that I would recommend before writing the questions is determine which kinds of question you would like to ask. Do you want to ask multiple choice, true/ false, fill in the blank, or short answer questions? I would also figure out how difficult of a question you would like to ask. Based on the links, I am going to assume the questions need to be fairly simple and straightforward. The links contain "primary" and "grade5" in them, so I would make sure the questions are accessible for fifth graders. Don't ask anything beyond their cognitive abilities, and keep question vocabulary simple enough to be accessible to a fairly young reader. I will write a few sample questions in order to provide you with a start.
- Which country has the highest carbon emissions?
- Which country has the lowest carbon emissions?
- Do both graphs agree on which country is the highest and lowest polluter?
- Which graph is easier to read? Why?
