Learning Objectives

• I can explain what division means and how it works.
• I can relate division to real-life sharing and grouping situations.
• I can solve simple two-digit by one-digit division problems using visual aids.
• I can explain my reasoning behind the division process.

---

Success Criteria

• Correctly solve at least 3 simple division problems.
• Clearly explain how division works using my own words and visuals.
• Use manipulatives or a number line to demonstrate division.
• Participate confidently in group discussions and activities.

---

Materials Needed

• Counters, cubes, or small objects (manipulatives) for grouping
• Number lines (large and color-coded)
• Division problem cards (with large, dyslexia-friendly fonts & color-coding)
• Whiteboard and markers
• Visual anchor chart with division vocabulary and examples

Lesson Procedure

1. Introduction & Engagement (5 minutes)

• Activate prior knowledge: Ask students what they think "division" means. Collect responses and write key phrases on the board in large, clear writing.
• I Can Statement: “I can explain what division means and how it works.”
• Show an anchor chart with visual division concepts (sharing equally and grouping).

2. Direct Teaching & Modeling (7 minutes)

• Explain division as sharing and grouping using manipulatives:
  Example: Sharing 12 counters equally among 3 students.

• Use number line to visually divide 12 into 3 groups (steps of 4).

• Verbalize thought process: “If we share 12 cookies among 3 friends, each friend gets 4 cookies. So 12 ÷ 3 = 4.”

• Write division problem on board: 24 ÷ 6 = ?

• Model grouping 24 into 6 equal groups using counters or drawing circles on the board.

3. Guided Practice (10 minutes)

• Hands-on activity:

  • Give each student 24 counters and ask them to divide them into 4 groups.
  • Provide number lines and ask them to jump steps counting how many items per group.

• Circulate, scaffold explanations, and ask each student:
  “How did you figure out your answer?”
  Encourage them to explain in their own words.

• Use color-coded materials for students who need extra reading support.

4. Independent Practice & Assessment (5 minutes)

• Each student solves 3 simple division problems on cards (e.g., 18 ÷ 3, 20 ÷ 5, 15 ÷ 5) using manipulatives or number lines.

• Students explain their answers orally.

5. Extension & Reflection (3 minutes)

• Advanced learners create their own division word problem using counters or a drawing and explain to the group how to solve it.

• Reflect together: “What is one thing you learned today about division?”

Differentiation Strategies

• Visual learners: Use number lines and color-coded anchor charts.
• Kinesthetic learners: Manipulate counters for real, tangible grouping and sharing.
• Students needing extra support: Provide step-by-step guided questions and model multiple times. Break problems into smaller steps.
• Language support: Use simple sentence frames for explanations (“I shared ___ counters among ___ groups, so each group has ___ counters.”)

---

Dyslexia-Friendly Options

• Use large, clear fonts such as OpenDyslexic or Arial Rounded MT Bold on all written materials.
• Use color coding consistently: e.g., blue for dividends, red for divisors, green for quotients.
• Keep text short and use bullet points for clarity.
• Provide oral instructions paired with visual aids.

---

Reflection for Teacher

• Did students use manipulatives effectively?
• Were they able to verbalize division concept in their own words?
• Which students benefited most from number lines?
• How can the next lesson be tailored to reinforce or extend these ideas?

This structured yet creative approach fosters a deep conceptual understanding of division, neatly aligned with Common Core standards and tailored to diverse learning needs.
