This is one of the worksheets I made when I taught Grade 3 in an international school in China. This worksheet was given after a presentation about different architecture styles around the world.
The article comes mainly from Wikipedia, but I deleted a few paragraphs that are two complicated for my students, and I also paraphrased a few sentences to make it easier.
I came up with the questions from the reading, and the answers are within the passage. Look for the key words and they will help you locate the answers.
