Title: Introduction to Fractions
Grade Level: 2nd Grade
Duration: 60 minutes
Objective:
- Students will understand the basic concept of fractions as parts of a whole.
- Students will be able to identify and represent fractions like 1/2, 1/3, and 1/4 using visual aids.
Materials Needed:
- Fraction circles or fraction bars
- Whiteboard and markers
- Chart paper and colored markers
- Construction paper
- Scissors
- Glue
- Worksheets with fraction problems
- Manipulatives: pie manipulatives, pizza cutouts, or paper folding strips
Common Core Standards:
- CCSS.MATH.CONTENT.2.G.A.3: Partition circles and rectangles into two, three, or four equal shares, describe the shares using the words halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths.

**Lesson Plan**
**Introduction (10 minutes):**
1. **Greeting and Warm-Up:**
- Begin with a short warm-up activity involving simple addition or subtraction to get students settled and ready to learn.
2. **Introduction to Fractions:**
- Start by asking if anyone knows what a fraction is. Allow a few volunteers to share their ideas.
- Explain that a fraction is a way to describe a part of a whole and show a visual aid such as a whole circle being divided into equal parts.
**Direct Instruction (15 minutes):**
3. **Key Concepts:**
- Write and explain the terms: numerator and denominator.
- **Numerator**: The top number of a fraction, representing how many parts we are talking about.
- **Denominator**: The bottom number of a fraction, representing the total number of equal parts the whole is divided into.
- Use fraction circles or bars to visually demonstrate 1/2, 1/3, and 1/4.
4. **Visual and Hands-on Learning:**
- Show a pizza cut into halves, thirds, and quarters. Emphasize how each piece represents a fraction of the whole pizza.
**Guided Practice (15 minutes):**
5. **Group Activity:**
- Divide students into small groups and provide each group with construction paper, scissors, and markers.
- Instruct each group to create their own fraction circles or bars by cutting out circles and dividing them into 2, 3, and 4 equal parts.
- Have groups label each part with the correct fraction.
**Independent Practice (10 minutes):**
6. **Worksheet Activity:**
- Distribute worksheets with drawings of divided shapes and ask students to write the fraction for each part.
- Include a mix of shapes divided into halves, thirds, and quarters.
**Assessment (10 minutes):**
7. **Interactive Quiz:**
- Conduct a quick interactive quiz using visual aids. Present different diagrams and have students raise their hands to identify the fraction being shown.
- Alternatively, use a digital tool if available, like a smartboard, to make the quiz more engaging.
**Closure (5 minutes):**
8. **Review and Reflect:**
- Wrap up the lesson by reviewing key points: what fractions are, how to write them, and how to identify them.
- Ask students to share one thing they learned about fractions today.
- Encourage students to practice at home by looking for fractions in everyday life, like cutting fruits or sharing snacks.
9. **Homework:**
- Assign a simple homework task to reinforce the lesson, such as drawing three objects divided into halves, thirds, and quarters and labeling the fractions.
**Note:**
Ensure to provide differentiated instruction as necessary, offering additional support or challenges based on individual students' needs. This could include one-on-one practice, extension activities for advanced learners, or simplified tasks for those struggling.
