Lesson Planning of Unit of Fractions
Subjects Mathematics
Grade II
Students` Learning Outcomes
- Recognize and name unit fractions up to 1/12
- Recognize fractions like two third, three fourth, four fifth and so on using 2/3, 3/4…
Information for Teachers
- Division of objects has now been advanced up to 12 parts and mixed parts like 2/3, 3/4, 4/5 and many other combinations.
- Key points will be one out of twelve out of 4, 4 out of 5.
- While teaching the lesson, the teacher should also consult textbook at all steps wherein and whenever it is applicable.
Material / Resources
Writing board, chalk/marker, duster, cards ½, 1/3,, ¼ shapes of different objects like circles rectangles, a list of months in a year properly displayed at some prominent place.
Introduction
- Ask: if you cut an apple in 2 equal parts and take one part how much of the apple do you have? (Expected answer would be as; Half)
- How can we write half in numbers? (Expected answer would be as; ½)
- How can we write one third in numbers? (Expected answer would be as; 1/3)
- How can we write one fourth in numbers? (Expected answer would be as; 1/4)
Development
|
Activity 1
- Ask the students about their birthdays. They will say different dates and months.
- Ask: How many months in year? (Expected answer would be as; 12)
So one year has 12 parts which are the 12 months.
|
JANUARY, FEBRUARY, MARCH, APRIL, MAY, JUNE, JULY, AUGUST,SEPTEMBER, OCTOBER,NOVEMBER, DECEMBER
|
- Ask: How many parts is the year divided in? (Expected answer would be as; 12)
- One month is one part out of 12
- How can we write it?
- (Expected answer would be as; 1/2, 1/3, 1/4, to 1/12)
- Encourage students to use their knowledge to write down the parts of the year in fractions.
- Say that a month can be called as one twelfth of a year (1/12).
- So the month of your birth is 12th portion of the year.

Activity 2
- Draw a rectangle on the board and divide it into three parts. Color the 2 parts to show the expressions of 2/3.
- Ask how many parts of the whole (3)
- How many color parts (2)
- How can we write it 2/3)
- Further explain the concept of three fourth by dividing the shape into 4 equal parts and then shade three portions.
- Always encourage the students to write the fraction.
- Correct if needed.

Activity 3
- Divide the class in-groups.
- Give each group a cut out shape.
- Ask them to think of any number from 1-12 and divide the shape in that many equal parts (with a pencil and ruler)
- Now cut-out out one part from the whole and write the fraction for it.
- How many total parts (10, 7, 8, etc.)
- How many parts do you have? (Expected answer would be as; 1)
- What’s the fraction? (Expected answer would be as; 1/10, 1/8, 1/7, etc.)
- Now say to the students to cut-out another part from the shape.
- Now you say How many parts do you have? (Expected answer would be as; )
- How can we show it in numbers? (Expected answer would be as; 2/10, 2/8, 2/7)
- Guide them on how to write these fractions. (Ask each time: how many parts of the whole? How many parts do you have?)
- Practice with different fractions in the same way.

Sum up/ Conclusion
- Conclude that we can divide things into many equal parts and write the fractions for them.
Assessment
- Distribute a sheet with different shapes divided into 12 parts.
- Ask them to color in shape according to the fraction that you say.
Follow up Tasks
- Ask them to make a story about dividing something into equal parts and sharing it.
- The story should mention one or two fractions
- Teacher is also required to involve the students in solving the problems given in the exercise at the end of unit/chapter.
