Lesson Plan of Equivalent Fractions

Lesson Plan of Equivalent Fractions

Subject Mathematics

Grade III

Students` Learning Outcomes

  • Write three equivalent fractions for a given fraction.

Information for Teachers

  • Multiplying the numerator sand denominator of a fraction by the same (non-zero) number, the results of the new fraction is said to be equivalent to the original fraction.

Equivalent Fractions

  • The word equivalent means that the two fractions have the same value.

Equivalent Fractions

  • While teaching the lesson, also consult textbook where and when applicable.

Material / Resources

Writing board, chalk/marker, duster, diagrams or chart of fractions, proper strips, mathematics textbook

Introduction

  • Divide the class into five groups.
  • Give long proper strip to each group and tell them to observe the coloured parts and colour only one part.
  • Ask one group to divide it into equal parts and colour only one part.

Equivalent Fractions

  • Ask second group to divide it into four equal parts and colour only two parts.

Equivalent Fractions

  • Ask third group to divide it into six equal parts and colour only two parts.

Equivalent Fractions

  • Ask fourth group to divide it into eight equal parts and colour only four parts.

Equivalent Fractions

  • Ask fifth group to divide it into twelve equal parts and colour only four parts.

Equivalent Fractions

  • Call each group to present their findings on the board and compare with each other`s work.
  • Are all fractions showing the same shaded area?
  • Explain the concept of equivalent fraction.

Equivalent Fractions

Development

Activity 1

  • Show the following figures to the students and ask them what is similar in all figures. (You can also draw these on the board)

Equivalent Fractions

  • Ask from students what will fourth diagram look like, how many parts are required for next figure.(16)
  • Give them chance to make next figure.
  • Repeat this activity for 1/3 and ¼ as well.

Activity 2

  • Write some equivalent fractions on the board.

Equivalent Fractions

  • Ask students to look at all numerators and predict the relation between them.
  • What could be the rule to get 2 and 4 from 1?
  • Ask students to look at all denominators and predict the relation between them. What could be the rule to get 4 and 8 from 2?

Equivalent Fractions

  • Give them some time for pair discussion to make a rule to get next fraction.
  • Ask students to use the rule and tell next two equivalent fractions.
  • Repeat this for 1/3.

Sum up / Conclusion

  • Conclude the lesson by stating that by multiplying/dividing the numerator and denominator of a fraction by the same number we get an equivalent fraction.

Assessment

  • Assign some fraction to the students and ask them to make next three equivalent fractions.

Equivalent Fractions

  • Give flashcards containing some fractions and ask students to pick all those fractions which are equivalent.

Equivalent Fractions

Follow up

  • Ask students to write next three equivalent fractions of ½, 2/4, 4/8, 3/5, 1/6 and also draw diagrams to represent each fraction.
