### Kungfu math p4 slide5 (multiples)

1. 1. Whole Numbers Multiples What will we learn today? • determining if a number is a multiple of a given 1-digit number, • listing the first 12 multiples of a given 1-digit number, • finding the common multiples of two given 1-digit numbers.
2. 2. We have learnt aboutFACTORS in the last lecture.
3. 3. It’s time for us to take it to a new level. Let’s try to learn some new concepts today! Multiples
4. 4. What is a multiple? The result of multiplying a number by an integer (not a fraction).In the multiplication table, we can see that 3 6 9 12 15 18 21 24 27 30 Therefore, 12 is a multiple of 3, because 3 × 4 = 12 But 7 is NOT a multiple of 3
5. 5. Factors and Multiples• Factors and multiples are associated with multiplication.• Factors are what you can multiply to get a number.• Multiples are what you get after multiplying a number by an integer. factors 3 x 4 = 12 multiple
6. 6. List the first 12 multiples of a given 1-digit numberFor example, “4”The first 12 multiples are 4 8 12 16 20 24 28 32 36 40 44 48
7. 7. What is the 8th multiple of the digit ‘4’?The first 12 multiples are 4 8 12 16 20 24 28 32 36 40 44 48
8. 8. What is the 8th multiple of the digit ‘4’?The first 12 multiples are 4 8 12 16 20 24 28 32 36 40 44 48 32 is the 8th multiple of the digit ‘4’.
9. 9. Find the common multiples of two given 1-digit numbersFind the common multiple of 3 and 8 which is less than 30.
10. 10. Find the common multiples of two given 1-digit numbersFind the common multiple of 3 and 8 which is less than 30. 3 6 9 12 15 18 21 24 27 30Step 1: List down the multiples of 3.
11. 11. Find the common multiples of two given 1-digit numbersFind the common multiple of 3 and 8 which is less than 30. 3 6 9 12 15 18 21 24 27 30 8 16 24 32 40 48 56 64 72 80Step 2: List down the multiples of 8.
12. 12. Find the common multiples of two given 1-digit numbersFind the common multiple of 3 and 8 which is less than 30. 3 6 9 12 15 18 21 24 27 30 8 16 24 32 40 48 56 64 72 80Step 3: Circle the common multiple(s).
13. 13. Find the common multiples of two given 1-digit numbersFind the common multiple of 3 and 8 which is less than 30. 3 6 9 12 15 18 21 24 27 30 8 16 24 32 40 48 56 64 72 80 The common multiple is 24.
14. 14. Are you ready to try out the questions?
