LESSON PLANNING OF UNIT FRACTIONS UP TO 1/12

Subject Mathematics

Grade 2^{nd}

Students` Learning Outcomes

- Recognize and name unit fractions up to 1/12.
- Recognize fractions like two-third, three-fourth, four-fifth and so on using 3/3, 3/4 ……………

Information for Teachers

- When the whole is divided into some equal parts, one part out of these equal parts is called unit fractions e.g. ½, 1/3, ¼ ….. 1/12.

- Two parts out of three equal parts is called two-third.

- Three parts out of four equal parts is called three –fourth.

Material / Resources

Writing board, chalk / marker, duster, textbook, shapes of different objects, chocolate bar

Introduction

- Bring a chocolate bar in the class or draw a picture of chocolate bar on the board.

- Divide the bar into two equal parts and shade one part if you are using a drawing.

- Now divide the bar into three equal parts and shade one part.

- Ask the students to represent the shaded part in fraction. (1/3)
- Now divide the bar into five equal parts and shade one part.

- Ask the students to represent the shaded part in fraction. (1/5)
- Tell the students that ½, 1/3, 1/5 is unit fractions. Mg

Development

Activity 1

- Display a chart having coloured strips on it.

- Ask the students to observe each strip and find out the number of equal parts, in which it has been divided.
- Find out how many equal parts are coloured?
- Represent in fractions coloured parts in each strip.
- Explain the students 1/5, 1/6… 1/12 are known as unit fractions.

Activity 2

Draw a rectangle on the board and divide it into three equal parts.

- Then coloured the parts of rectangle to represent as fraction 2/3.
- Ask students how many parts are of the whole? (3)
- How many parts are shaded? (2)
- So how we represent this fraction? (2/3)
- How will we read it? (Two-third)
- Make another rectangle and divide it into four equal parts.

- Shade three parts and ask the students how many parts are shaded? (3)
- How will we represent this fraction? (3/4)
- Repeat this activity with 4/5 and 5/6 ask fraction every time from the students.
- Encourage their answer and guide them.

Activity 3

- Draw the following shapes on the board.
- Ask the students to shade the given fraction.

- Encourage the students and at the end demonstrate on the board.

Sum up / Conclusion

- Unit fractions are one part out of total equal parts.

Two-third is written as 2/3.

Three-fourth is written as ¾.

Assessment

- Ask the students to draw a circle and represent the following unit fractions. ½, 1/3, ¼, 1/5, 1/6.

- Write the fractions for the following.

- Shade the following fractions.

Follow up

- Divide the following rectangle into six equal parts and represent the fraction. 5/6

- Bread was divided into 12 equal parts & you take 3 slices, your sister takes 4 slices & your mother takes 5 slices.

- Write fraction for you, your sister & your mother.
- Ask the students to solve the questions given in their textbook.
