When you find a word you don't know, a dictionary or glossary can help! A dictionary is a big list of word meanings, while a glossary is a mini-dictionary at the back of a book. Both use alphabetical order (A to Z) and guide words at the top of the page to help you search. For example, if you are looking up the word "explore," look between the guide words "exit" and "extra."

Why Dictionary Skills Matter in Third Grade
In 3rd grade, students transition from learning to read to reading to learn. Encountering unfamiliar words is a natural part of this shift. Knowing how to navigate a dictionary and a textbook glossary empowers students to build their vocabulary independently. This core skill builds on basic alphabetical ordering learned in 2nd grade, adding the use of guide words, pronunciation guides, and context clues.
Tips for Supporting Dictionary Practice
- Spot the Guide Words: Help kids understand that the two words at the top of a dictionary page show the first and last words on that page.
- Glossary vs. Dictionary: Remind children to check the glossary at the back of their science or social studies textbook first, as it focuses specifically on the book's topic.
- Use Context Clues: Encourage kids to read the entire entry to choose the definition that fits their sentence best.
