Pre-Reading Trivia

Students will write down one thing they already know about the subject and then read five more facts and discuss. These facts are fun, and the students will enjoy learning about the subject before reading more.

• Give 1 minute for students to write what they already know (no pressure—best guess is fine).

• Read the five facts together. After each fact, do ask a student for their opinion, was it surprising?

• Set a purpose by asking students to highlight/underline one fact they want to learn more about during the reading.

Reading Passage

The text is a high-interest reading passage with set paragraphs, roughly three to four paragraphs long. It contains a variety of themes about the topic, anywhere from history to technology. The passage is between 250 and 350 words in length.

Vocabulary Questions

Practice seven key words from the text in this section across two activities. First section is scrambled words where students will unscramble three words given a clue for each. The second section is a word to meaning matching activity.

• Before starting, have some students read out words they underlined in the passage. Ask students to say the word and read aloud the sentence(s) around each word.

• Ask students to do scrambled words and the matching exercise in pairs then go through answers as a class.

• For the scrambled spelling task, get four pairs to come up to the board and write the words for extra practice with the other student reading out the clue.

• For the matching task, prompt students to give full sentences: “I matched ___ with ___ because ___.”
