Lesson Planning of Multiplication of Fraction with Whole Number
Subject Mathematics
Grade 4th
Students` Learning Outcomes
- Multiply fractions with whole numbers.
Information for Teachers
- Multiplying a fraction by whole number follows the same rules as multiplying two fractions.
- A whole number can be considered as a fraction with a denominator of 1.
- Therefore when a fraction is multiplied by a whole number the numerator of the fraction is multiplied by the number.
- The denominator is multiplied by 1 which does n`t change the denominator.
- While teaching the lesson, teacher should also consult with textbook at all steps where and when required.
Material/ Resources
Writing board, chalk, marker, duster, chart paper, textbook
Introduction
- Write on the board: 1 whole and ask:
- How many halves (1/2) it has? [2]
- Can I say it is as 2 x ½? [Yes]
- Write the following on the board and make students repeat with you.
- Ask the students; what we get if we divide any number with 1. i.e. 7 ÷ 1 = 7 / 1 = 7 (Repeat with other numbers)
- Announce that today we will talk about multiplication of fractions with whole numbers.

Sum up / Conclusion
- Conclude lesson with the following points.
- Multiplying a fraction by whole number follows the same rules as multiplying two fractions.
- Each whole number can be written in fraction form, i.e. 12 = 12/1, 35 = 35 / 1
- Therefore when a fraction is multiplied by a whole number the numerator of the fraction is multiplied by the number.
Assessment
- Give the following questions to solve by showing all steps of multiplication.
Follow up
- Give following questions to do in their notebooks.
- A group of farmers planted 72 fields of vegetables. They planted 1 / 6 parts of the fields with cabbage. How many fields of cabbage did the farmer plant?
- Alana wants to cut down on sugar-so she decided to only use 2/3 of the amount of sugar mentioned in the recipe of 400 gm. How much sugar will she needed
