Active learning ideas

Using a Dictionary and Thesaurus

Active learning works for this topic because fourth graders need hands-on practice to see how dictionary and thesaurus entries function beyond simple definitions. When students physically dissect entries or hunt for synonyms, they build confidence in using these tools independently.

Think-Pair-Share: Entry Dissection

Give each pair a printed dictionary entry for an unusual but age-appropriate word. Partners identify each part of the entry (definition, pronunciation, part of speech, example sentence) and then explain to the class what they learned that they could not have guessed from the definition alone.

Explain how a dictionary provides more than just a word's definition.

Facilitation Tip

During Entry Dissection, ask students to highlight the part of speech in one color and syllable breaks in another to make the entry’s structure visible.

What to look for

Provide students with a short paragraph containing a repeated word. Ask them to use a thesaurus to find two different synonyms for the word and rewrite the sentence twice, each time using a different synonym. Then, ask them to use a dictionary to find the part of speech for the original word and one of the synonyms.

Gallery Walk: Synonym Shades

Post five anchor words around the room, each with a list of four thesaurus synonyms. Students rotate, writing brief notes on sticky notes about which synonym fits best in a provided sentence and why. Debrief as a class to surface the difference between denotation and connotation.

Compare the benefits of using a thesaurus versus a dictionary for writing.

Facilitation Tip

For Synonym Shades, provide sticky notes in two colors so students can mark synonyms with similar and different connotations.

What to look for

On one side of an index card, write a word. On the other side, ask students to write: 1) The part of speech for the word. 2) One piece of information from a dictionary entry that is NOT the definition. 3) One synonym for the word from a thesaurus.

Activity 03

• Stations Rotation
• 25 min · Small Groups

Collaborative Challenge: Reference Race

Small groups receive the same set of five questions that require using both a dictionary and a thesaurus, for example, 'Find a synonym for angry that would fit a formal letter, and confirm its part of speech.' Groups race to answer correctly, then share strategies for navigating each tool efficiently.

Assess the most efficient way to find a specific word's meaning in a digital dictionary.

Facilitation Tip

In Reference Race, set a timer and circulate with a clipboard to listen for students explaining their word choices aloud.

What to look for

Pose the question: 'When might you choose a word from a thesaurus that sounds similar but has a slightly different meaning than the original word?' Facilitate a discussion where students share examples and explain why precise word choice matters in writing.

Individual Practice: Revise a Repetitive Paragraph

Each student receives a short paragraph that overuses one word. Using a thesaurus and then a dictionary to verify meaning, students revise the paragraph. They annotate each change with a note on why that synonym fits the context better.

Explain how a dictionary provides more than just a word's definition.

A few notes on teaching this unit

Experienced teachers approach this topic by modeling how to read a full dictionary entry, not just the first definition. They avoid assuming students will transfer skills from digital tools to print ones without explicit instruction in entry anatomy. Research shows that when students practice mapping parts of an entry, they retain more than when they only look up words to confirm meaning.

Successful learning looks like students confidently locating pronunciation guides, parts of speech, and multiple definitions in a dictionary. They should also explain why a thesaurus’s synonyms may not always fit the context of their writing.

Watch Out for These Misconceptions

• During Think-Pair-Share: Entry Dissection, watch for students focusing only on the first definition and ignoring pronunciation or part of speech.

  During Think-Pair-Share: Entry Dissection, have students circle the pronunciation guide and underline the part of speech before looking at any definitions to shift their attention to the entry’s structure.

• During Gallery Walk: Synonym Shades, watch for students selecting synonyms without considering connotation or context.

  During Gallery Walk: Synonym Shades, ask students to write a short sentence using the synonym they selected to justify their choice and discuss it with peers.

• During Collaborative Challenge: Reference Race, watch for students assuming any synonym from the thesaurus will work in their sentence.

  During Collaborative Challenge: Reference Race, require students to use a dictionary to confirm the part of speech of the synonym they chose before using it in their sentence.
