Lesson Plan of Common fractions

Subject Mathematics

Grade III

Students` Learning Outcomes

• Express the fractions in figures and vice versa.

Information for Teachers

• A fraction is a way of representing division of a “whole” into parts.
• A general rule to write a fraction is as;

• The bottom part of fraction represents denominator which means total number of equal parts of the whole.

• Top part of fraction represents numerator which means desired or require parts of whole.

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

Material / Resources

Writing board, chalk/marker, duster, any fruit, playing dough/clay, piece of papers/strips/cards, box filled with the figures flash cards divided into two, equal or unequal parts

Introduction

• Show a square piece of chart paper to the students.
• Ask the students to fold the paper in a way that it is divided into two equal parts.
• Explain that whole square is divided into two equal parts (use proper mathematical vocabulary during explanation).
• Write this activity on the board to show the fraction for example:

Development

Activity 1

• Give playing dough/clay to students and ask them to make a ‘Roti’ or ‘Nan’ in groups.

• Ask them to use a paper cutter/ruler to divide it into two halves.
• Ask in how many equal parts you have divided the Nan /bread? Write it on the board.
• Ask how many pieces they will take for ‘half’, write on the board?
• Guide students to write a fraction by writing total number of equal parts below a bar and number of concerning parts above the bar e.g. ½ .
• Introduce vocabulary numerator and denominator for the related numbers in the fraction to the students for better understanding of the concept.

• Ask them to make pieces of this ‘Nan/Bread’ for their four friends and show in fractions how much each would get?

Activity 2

• Divide the class into four groups.
• Provide those papers of different colors in different shapes e.g. square, triangle, rectangle, and circle.

• Ask students to divide different shapes into two equal parts.
• Tell them to paste their work on a big chart paper and write their fraction.
• Call all groups one by one to present their work and let other students ask questions so concept is clear to everyone.

Activity 3

• Provide a k sheet to students with different shapes and pictures.
• Ask them to draw a line to divide them in to two equal parts.
• Ask students to color half of the shapes and write fraction for the coloured part.
• Work sheet may carry following questions.
• Divide each shape into two equal parts and shade one part.

• Write fraction for the color parts.

• Encircle the figures to show the given fractions.

• Draw any shape to show the following by making a loop.

Sum up / Conclusion

• Ask following questions to wrap up the lesson.
  • • What is the total /part of any figure or shape called?
    • What does denominator stand for?
    • What does numerator stand for?

Assessment

• Give few diagrams or shapes divided into two parts, equally and unequally. Ask students to circle all those figures which are divided into two equal parts and write their fractions.
• Give some diagram of shapes to students and ask them to draw lines to divide into fractions and color.

Follow up

• Ask students to draw 5 shapes on notebooks and make as many as equal number of parts for the figures.
