Common Core State Standards (CCSS) Alignment

CCSS.Math.Content.3.OA.A.2
Interpret products of whole numbers, e.g., interpret 5 × 7 as the total number of objects in 5 groups of 7 objects each.
(Foundational for understanding multiplication and division relationships.)

CCSS.Math.Content.3.OA.B.6
Understand division as an unknown-factor problem. For example, find 32 ÷ 8 by finding the number that makes 32 when multiplied by 8.

CCSS.Math.Content.3.OA.C.7
Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division or properties of operations.

Learning Objectives ("I can" statements)

• I can understand division as sharing or grouping equally.
• I can use objects and drawings to represent division problems.
• I can solve division problems using known multiplication facts.
• I can explain my thinking using math vocabulary related to division.

---

Success Criteria

• I can model dividing objects into equal groups with physical items.
• I can write division equations to match word problems or stories.
• I can use multiplication facts to solve division problems.
• I can explain how I solved my division problem using complete sentences.

---

Materials Needed

• Small counters or cubes (about 100 per group)
• Whiteboards and dry-erase markers
• Printed division problem cards with dyslexia-friendly font (e.g., OpenDyslexic or Arial)
• Visual fraction/division charts
• Story cards with division scenarios
• Timer
• Chart paper and markers

Lesson Outline

1. Introduction & Goal Setting (10 minutes)

Activity: Meet and Greet with Division

• Begin by gathering students in a circle.
• Show a basket with 24 counters.
• Ask: “If we wanted to share these counters equally into 4 groups, how many would be in each group?”
• Write the division equation 24 ÷ 4 = ? on the board.
• Introduce the vocab words: divide, groups, equal, remainder.
• Read aloud a division story problem using a dyslexia-friendly font and clear language. For example:
  "Samantha has 20 pencils. She wants to put them into 5 equal boxes. How many pencils will be in each box?"

Teacher prompts:

• "I can understand division as sharing equally."
• Discuss the importance of division in everyday life.

2. Hands-On Group Activity (20 minutes)

Activity: Hands-On Division Stations (Groups of 2-3 students)

• Students use counters to physically divide into equal groups based on problem cards.
• Each card includes a division problem, e.g., 15 ÷ 3, 18 ÷ 6.
• Students:
  1. Count out the total counters.
  2. Physically separate them into equal groups.
  3. Record the division equation on their whiteboard.
  4. Write or verbally explain their reasoning.

Differentiation:

• For students with learning differences or dyslexia, provide visual step-by-step cards with images.
• Use bold, dyslexia-friendly fonts.
• Allow these students to verbalize their reasoning before writing.

Support for Struggling Learners:

• Provide multiplication fact charts for reference.
• Use manipulatives as concrete supports.

---

3. Interactive Whiteboard & Vocabulary Matching Game (10 minutes)

• Using a simple interactive smartboard or printed cards for non-tech classrooms:
• Match division vocabulary words ("divide," "quotient," "equal groups," "remainder") with their meanings and pictures.
• Involve all students in reading the cards aloud.
• Discuss real-world examples for each word.

Dyslexia-Friendly Tip:
Use large fonts, highlight keywords, and pair words with icons.

---

4. Guided Practice - Word Problems (10 minutes)

• Present 3 division word problems on the board/read aloud.
• Students solve on individual whiteboards.
• Randomly select students to explain their thought process, encouraging math vocabulary.

Sample Problems:

• "There are 30 crayons to share equally among 5 friends. How many crayons per friend?"
• "A baker made 24 cookies and put them into trays of 4 cookies each. How many trays?"

---

5. Extension for Advanced Learners (5 minutes)

• Challenge: “If I know that 5 × 6 = 30, can you find 30 ÷ 5 without counting the objects?”
• Introduce the idea of division as an unknown factor problem.
• Provide task cards with higher division facts (up to 100) for these students.

---

6. Wrap-Up Reflection & Exit Ticket (5 minutes)

• Review learning objectives with students using “I can” statements.
• Exit Ticket:
  Write or draw an example of a division problem solved today.
• Encourage students to share what they enjoyed or found challenging.

---

Differentiation Strategies

Student Need	Strategy
Students with Dyslexia	Use dyslexia-friendly fonts; provide oral instructions and visual support; multi-sensory learning activities.
Students Needing More Help	Use manipulatives and concrete examples; frequent checks for understanding; peer partners.
Advanced Learners	Provide unknown-factor division problems; introduce related multiplication and division puzzles.
English Language Learners	Use visuals, gestures, clear concise language; pair with bilingual students or visual aids.

---

Assessment Strategies

• Observation during hands-on activities (participation, problem-solving approaches)
• Whiteboard responses during guided practice
• Exit ticket drawings/writing to check individual understanding
• Verbal explanations using division vocabulary

---

Reflection for Teacher

• Were all students able to use manipulatives effectively?
• Did students use math vocabulary confidently?
• What adjustments are needed for next lesson on division with remainders?

---

This plan creates an engaging and accessible division introduction with plenty of tactile, visual, and verbal opportunities aligned to 3rd grade Common Core standards, fostering both understanding and confidence.
