LESSON PLANNING OF FRACTION IN NUMERICAL FORMS

Subject Mathematics

Grade 2^{nd}

Students` Learning Outcomes

- Represent half, one third and quarter in numerical forms as ½, 1/3, ¼ etc.
- Shade the equal parts of a given figure to match a given fraction.

Information for Teachers

- One half is written as ½ numerically.

- One third is written as 1/3 numerically.

- One fourth is written as ¼ numerically.

Material / Resources

Writing board, chalk / marker, duster, card paper, textbook

Introduction

- Ask the students what is a fraction? (Expected answer would be as; dividing whole into equal parts)

- Draw the picture of bread on the board.
- If we divide bread in two equal parts so, each part is called “a half”

- If we divide bread in three equal parts, then each part is called “one third”.

- Similarly we can divide a piece of brad into 4, 5, and 6 …… equal parts respectively.

Development

Activity 1

- Divide the class into four groups.
- Distribute equal size rectangular card papers among the groups.
- Ask the groups to fold the card in half.
- Ask two groups to fold the paper in half length-wise and two groups width-wise.

- Ask the groups to open the card papers.

- Ask them in how many parts the card paper has been divided? (2)
- Are these parts equal? (Yes)
- Let us shade in its half portion.

- How we represent shaded part numerically?
- Write on the board:

__Coloured parts__- Total parts = 1/2
- We represent it as ½

Activity 2

- Now ask the groups to again fold in the same way.
- Groups will double it length wise and width wise just like before.

- Ask the student to open their card papers.
- After unfolding they will find the lines like this.

- Now ask in how many parts the paper has been divided? (4)
- Is every part equal? (Yes)
- Shade one part.

- How will we represent the shaded part numerically?
- Write on the board: ¼

- We will read it as one-fourth.
- Explain to the students that one fourth or ¼ means one part out of four equal parts.
- Similarly one third or 1/3 means one part out of three equal parts.

Activity 3

- Distribute the following worksheet among the students and as them to shade the given fractions.

Sum up / Conclusion

- One half is represented as ½.

- One third is represented as 1/3.

- One fourth is represented as ¼.

Assessment

- Represent coloured parts in fraction.

Follow up

- Draw rectangles and represent the following equivalent fractions.

- Ask the students to solve the questions given in their textbook
