Grade 3 Skills Workbook (Unit 5)

Objective

Students will identify key facts about light (speed, form of travel, and white light) from the informational text "What Is Light?" and practice forming adverbs by adding the suffix -ly to adjectives.

Materials

• Grade 3 Skills Workbook (Unit 5) — worksheets 2.1, 2.2, and 2.3 (photocopies for each student)
• Pencils
• Whiteboard or chart paper (optional, for reviewing answers)

Warm-up (~5 min)

• Write the question on the board: "What do you already know about light?"
• Ask 3–4 students to share one idea aloud (e.g., where light comes from, how we see things).
• Tell students: "Today we're going to read about what light is, how fast it travels, and how it moves. Then we'll practice adding -ly to words to make adverbs."

Main Activity (~25 min)

1. Read aloud (10 min): Hand out worksheet 2.3 ("What Is Light?"). Read the passage aloud as a class, or have volunteers take turns reading paragraphs. Pause after each paragraph to check understanding (e.g., "What did we just learn about the sun?").
2. Answer questions (10 min): Hand out worksheet 2.1. Have students work independently or in pairs to answer the multiple-choice and short-answer questions using the passage from 2.3 to find answers (speed of light, how light travels, what determines visibility of light waves, meaning of "reflect," description of white light, sources of light, and the main idea).
3. Review answers (5 min): Go over the correct answers as a class:
4. Q1: C (186,000 miles a second in a vacuum)
5. Q2: B (waves)
6. Q3: D (the length of the wave)
7. Q4: A (send back)
8. For Q5–7, call on a few students to share their written answers.

Wrap-up / Exit Ticket (~10 min)

• Hand out worksheet 2.2 (Making Adverbs With the Suffix -ly).
• Have students complete sentences 1–4 independently (underlining the verb, adding -ly to the adjective, circling the adverb, and answering the "how" question).
• Collect worksheet 2.2 as the exit ticket to check understanding of adverb formation.
• If time is short, students may finish sentences 5–6 for homework.

If Time Remains

• Have students complete the two open-ended sentence-writing prompts at the bottom of worksheet 2.2 (using "slowly" and "loudly" in original sentences that describe a verb). Ask a few volunteers to share their sentences aloud.
