Lesson 13-Ways to Multiply and Divide- Here are some ways to multiply and divide numbers:
Multiplication:
- Standard Multiplication: Multiply each digit of one number by each digit of the other number, starting from the right, and add up the partial products.
Example: 345 x 12 345 x 12
690 (partial product: 345 x 2) +3450 (partial product: 345 x 1)
4140 (product)
- Multiplication by a Power of 10: When multiplying a number by 10, 100, 1000, and so on, simply shift the digits to the left by the corresponding number of zeros.
Example: 56 x 100 = 5600
- Multiplying by 1 or 0: Multiplying any number by 1 results in the same number. Multiplying any number by 0 always gives 0.
Example: 56 x 1 = 56 56 x 0 = 0
Division:
- Long Division: Divide the dividend (the number being divided) by the divisor (the number dividing the dividend) using long division method. It involves dividing, multiplying, subtracting, and bringing down the next digit.
Example: 126 ÷ 4 _______ 4 | 126 – 12 (4 times 3 is 12) — 6 (subtract 12 from 12, bring down 6) – 4 (4 times 1 is 4) — 2 (subtract 4 from 6)
- Division by a Power of 10: When dividing a number by 10, 100, 1000, and so on, simply shift the digits to the right by the corresponding number of zeros.
Example: 5600 ÷ 100 = 56
- Division by 1: Dividing any number by 1 results in the same number.
Example: 56 ÷ 1 = 56
These are some basic methods of multiplying and dividing numbers. Remember to practice these techniques to improve your skills and speed in arithmetic operations.

Application of Class 5 Maths Lesson 13-Ways to Multiply and Divide
The application of Class 5 Maths Lesson 13 on Ways to Multiply and Divide is to develop the foundational skills and understanding necessary for performing multiplication and division operations accurately and efficiently. Here are some practical applications of these concepts:
- Calculating Total Costs: Students can apply their multiplication skills to calculate the total cost of items when given the price per unit and the quantity. For example, if a bag of apples costs $2 and a person wants to buy 5 bags, they can use multiplication to find the total cost as 5 bags x $2 = $10.
- Sharing Items Equally: Division skills can be applied in situations where items need to be shared equally among a group. For instance, if there are 24 cookies to be distributed equally among 4 friends, students can use division to find out how many cookies each friend will get, which is 24 cookies ÷ 4 friends = 6 cookies per friend.
- Scaling Recipes: Multiplication skills are helpful when scaling recipes up or down. If a recipe requires ingredients for 4 servings and needs to be doubled to serve 8, students can use multiplication to adjust the ingredient quantities accordingly.
- Understanding Measurements: Multiplication and division are also useful for converting measurements. For example, students can convert centimeters to millimeters by multiplying the length in centimeters by 10 or convert liters to milliliters by multiplying the volume in liters by 1000.
- Determining Area and Perimeter: Students can apply multiplication to find the area of rectangles or squares. For instance, to find the area of a rectangle with length 5 units and width 8 units, students can multiply the length and width: 5 units x 8 units = 40 square units.
These applications demonstrate how the concepts of multiplication and division learned in Class 5 Maths Lesson 13 can be used in various real-life scenarios, developing practical problem-solving skills and enhancing mathematical fluency.
Case Study on Class 5 Maths Lesson 13-Ways to Multiply and Divide
Real-Life Application of Class 5 Maths Lesson 13 – Ways to Multiply and Divide
Scenario: Farmer’s Field
Let’s consider a case study involving a farmer who needs to apply the concepts learned in Class 5 Maths Lesson 13 – Ways to Multiply and Divide to solve a real-life problem.
Background: Mr. Smith is a farmer who owns a rectangular field. He wants to divide his field into smaller sections to grow different crops. The field has a length of 120 meters and a width of 80 meters.
Problem: Mr. Smith wants to divide the field into smaller rectangular sections, each with a length of 40 meters and a width of 20 meters. He needs to determine how many sections he can create and how much area each section will cover.
Solution:
- Determining the Number of Sections: To determine the number of sections, we need to divide the total length of the field by the length of each section. Similarly, we divide the total width of the field by the width of each section.
Number of sections in length = Total length of field ÷ Length of each section = 120 meters ÷ 40 meters = 3 sections
Number of sections in width = Total width of field ÷ Width of each section = 80 meters ÷ 20 meters = 4 sections
Hence, Mr. Smith can create a total of 3 sections in length and 4 sections in width, resulting in a total of 3 x 4 = 12 smaller rectangular sections.
- Determining the Area of each Section: To determine the area of each section, we multiply the length and width of each section.
Area of each section = Length of each section x Width of each section = 40 meters x 20 meters = 800 square meters
Hence, each smaller rectangular section will cover an area of 800 square meters.
Conclusion: Through the application of multiplication and division concepts learned in Class 5 Maths Lesson 13, Mr. Smith was able to determine that he can create 12 smaller rectangular sections in his field, each covering an area of 800 square meters. This knowledge helps him plan and manage his crops more effectively, ensuring efficient use of his farmland.
