LESSON PLANNING OF UNIT FRACTIONS UP TO 1/12
Subject Mathematics
Grade 2nd
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 3/3, 3/4 ……………
Information for Teachers
- When the whole is divided into some equal parts, one part out of these equal parts is called unit fractions e.g. ½, 1/3, ¼ ….. 1/12.
- Two parts out of three equal parts is called two-third.
- Three parts out of four equal parts is called three –fourth.
Material / Resources
Writing board, chalk / marker, duster, textbook, shapes of different objects, chocolate bar
Introduction
- Bring a chocolate bar in the class or draw a picture of chocolate bar on the board.
- Divide the bar into two equal parts and shade one part if you are using a drawing.
- Now divide the bar into three equal parts and shade one part.
- Ask the students to represent the shaded part in fraction. (1/3)
- Now divide the bar into five equal parts and shade one part.
- Ask the students to represent the shaded part in fraction. (1/5)
- Tell the students that ½, 1/3, 1/5 is unit fractions. Mg
Development
Activity 1
- Display a chart having coloured strips on it.
- Ask the students to observe each strip and find out the number of equal parts, in which it has been divided.
- Find out how many equal parts are coloured?
- Represent in fractions coloured parts in each strip.
- Explain the students 1/5, 1/6… 1/12 are known as unit fractions.
Activity 2
Draw a rectangle on the board and divide it into three equal parts.
- Then coloured the parts of rectangle to represent as fraction 2/3.
- Ask students how many parts are of the whole? (3)
- How many parts are shaded? (2)
- So how we represent this fraction? (2/3)
- How will we read it? (Two-third)
- Make another rectangle and divide it into four equal parts.
- Shade three parts and ask the students how many parts are shaded? (3)
- How will we represent this fraction? (3/4)
- Repeat this activity with 4/5 and 5/6 ask fraction every time from the students.
- Encourage their answer and guide them.
Activity 3
- Draw the following shapes on the board.
- Ask the students to shade the given fraction.
- Encourage the students and at the end demonstrate on the board.
Sum up / Conclusion
- Unit fractions are one part out of total equal parts.
Two-third is written as 2/3.
Three-fourth is written as ¾.
Assessment
- Ask the students to draw a circle and represent the following unit fractions. ½, 1/3, ¼, 1/5, 1/6.
- Write the fractions for the following.
- Shade the following fractions.
Follow up
- Divide the following rectangle into six equal parts and represent the fraction. 5/6
- Bread was divided into 12 equal parts & you take 3 slices, your sister takes 4 slices & your mother takes 5 slices.
- Write fraction for you, your sister & your mother.
- Ask the students to solve the questions given in their textbook.
