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.
