### Lesson Plan: Introduction to Fractions
---
#### Grade Level: Year 2
#### Subject: Mathematics
#### Topic: Introduction to Fractions
#### Duration: 60 minutes
---
**Objectives:**
1. Students will understand the concept of fractions as parts of a whole.
2. Students will be able to identify and represent simple fractions (1/2, 1/3, 1/4).
3. Students will practice dividing objects and shapes into equal parts.
**Materials:**
- Whiteboard and markers
- Fraction circles or fraction bars
- Paper and pencils
- Printable fraction worksheets
- Colored pencils or markers
- Construction paper and scissors
- Interactive fraction games (optional, if technology is available)
---
**Standards:**
- Common Core Mathematics 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.
---
**Introduction (10 minutes):**
1. **Warm-up Activity:**
- Begin with a quick oral review of basic shapes (circle, square, rectangle).
- Ask students if they can think of times they’ve seen things cut into parts (e.g., a pizza sliced into pieces, or breaking a chocolate bar).
2. **Objective Introduction:**
- Introduce the term “fraction” by explaining that it comes from the word “fracture” which means to break.
- On the whiteboard, demonstrate by drawing a circle (symbolizing a pizza) and dividing it into two equal parts. Describe it as “two halves,” and label each part with “1/2.”
---
**Direct Instruction (15 minutes):**
1. **Interactive Demonstration:**
- Use fraction circles or fraction bars to show 1/2, 1/3, and 1/4.
- Explain that fractions represent equal parts of a whole. Show students how to divide shapes into equal parts using different examples (circles and rectangles).
2. **Vocabulary:**
- Introduce key vocabulary: Fraction, Whole, Half (1/2), Third (1/3), Quarter (1/4).
- Write these terms on the whiteboard and have students repeat them aloud.
---
**Guided Practice (15 minutes):**
1. **Group Activity:**
- Divide students into small groups and provide each group with fraction circles or fraction bars.
- Ask students to partition their shapes into halves, thirds, and fourths.
2. **Worksheets:**
- Distribute simple fraction worksheets where students color in fractions of shapes.
- Walk around and assist students as needed, ensuring they understand how to partition and label fractions.
---
**Independent Practice (10 minutes):**
1. **Hands-on Activity:**
- Hand out construction paper and scissors to each student.
- Instruct students to cut out shapes and divide them into halves, thirds, and fourths. Allow students to color and label their fractions.
---
**Assessment (5 minutes):**
1. **Review and Oral Quiz:**
- Call on students individually or in small groups to describe and identify the fractions they have created.
- Evaluate their understanding by asking questions such as:
- "Show me a shape divided into halves. How many parts are there?"
- "Which fraction represents three equal parts?"
---
**Closure (5 minutes):**
1. **Summary:**
- Recap the lesson by revisiting the main points about fractions.
- Highlight the importance of equal parts in fractions.
2. **Connection to Real Life:**
- Discuss real-life examples where fractions are used, like cooking measurements or sharing items equally.
---
**Extension Activities:**
- For advanced students, introduce more complex fractions (e.g., 2/4, 3/4).
- Use interactive fraction games online or on tablets for further practice.
**Homework:**
- Assign a worksheet that involves identifying and coloring different fractions of shapes.
---
**Reflection:**
After the lesson, observe which parts of the lesson were most engaging and which parts might need more clarity or adjustment for next time. Note any students who struggled with the concept and plan follow-up activities to reinforce learning.
