LESSON PLANNING OF FRACTION IN NUMERICAL FORMS

Subject Mathematics

Grade 2nd

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

Fraction in Numerical Forms

  • 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
