Slide 2 Revision on Multiplication concept Our Dear parents: Kindly you are asked to guide your little son/daughter throughout the slide show by pressing the sound bottom when needed. Slide 3 How many wings do 5 chicks have? Each chick has 2 wings So 2 + 2 + 2 + 2 + 2 = 10 OR .. We can use another operation Multiplication Operation 2 X 5 = 10 Slide 4 If each student has 3 books, so how many books do 6 students have? Addition Operation So 3 + 3 + 3 + 3 + 3 + 3 = 18 OR .. We can use another operation Multiplication Operation 3 X 6 = 18 Slide 5 Repeated Addition Slide 6 Its a birthday party, use mathematics to prepare for the party. Now its the story time. Its a birthday party, Lets prepare for it using Mathematics. Now its the story time. Its a birthday party, Lets prepare for it using Mathematics. Slide 7 Jane wants to put 3 pieces of cake in each plate, if she has 8 plates. How many pieces of cake does she want in all? Using Addition Operation 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 Using Multiplication Operation 3 X 8 = 24 Pieces of cake It means 3 is repeated 8 times Slide 8 Jane wants to decorate the reception by putting 5 flowers in each vase. If she has 6 vases. How many flowers does she want in all? Add. Sentence: 5 + 5 + 5 + 5 + 5 + 5 = 30 Flowers Multiplication Sentence: 5 x 6 = 30 Flowers 5 is repeated 6 times MULTIPLICATION CONCEPT JANES BIRTHDAY PARTY Slide 9 Jane wants to put 6 candles in each cake. If she has 5 cakes. How many candles does she want in all? Add. Sentence: 6 + 6 + 6 + 6 + 6 = 30 Candles Multiplication Sentence: 6 x 5 = 30 Candles 6 is repeated 5 times Slide 10 So in multiplication if we change the multiples places, the result will be the same. Slide 11 Jane asked 3 of her friends to get fireworks with them, but no one remembered. How many fireworks did she get? Add. Sentence: 0 + 0 + 0 = 0 Fireworks Multiplication Sentence: 0 x 3 = 0 Fireworks 0 is repeated 3 times MULTIPLICATION CONCEPT JANES BIRTHDAY PARTY Slide 12 Now its the party time. Jane has got 1 present from each friend, if she has 7 friends. How many presents did she get? Add. Sentence: 1 + 1 + 1 + 1 + 1 + 1 + 1 = 7 presents Multiplication Sentence: 1 x 7 = 7 presents 1 is repeated 7 times MULTIPLICATION CONCEPT JANES BIRTHDAY PARTY Slide 13 Meaning of multiplication: Repeated addition and its sign is called times (x). Multiplication property: 3 x 2 = 2 x 3 = 6 ( If we change the multiples places, the result will be the same). Multiplying by One: Any number x One = The same number Multiplying by Zero: Any number x Zero = Zero MULTIPLICATION CONCEPT WRAPPING UP Slide 14 Complete the following: a) 5 + 5 + 5 + 5 = .. X = b) 7 x 8 = 7 + 7 + 7 + . + . + . + . + . = c) 6 x 9 = .. X . = d) 3 x 1 = . e) 8 x . = 0 MULTIPLICATION CONCEPT GUIDED PRACTICE Slide 15 Explain this drawing using addition and multiplication sentences: Set 1 Set 2 Set 3 Addition sentence : 4 + 4 + 4 = 12 Multiplication sentence: 4 x 3 = 12 4 items in 3 sets. Slide 16 Choose the right answer: Choose the right answer: The multiplication sentence that represents the following drawing is: MULTIPLICATION CONCEPT INDEPENDENT PRACTICE Slide 17 Slide 18 Choose the right answer: 6 + 6 + 6 + 6 = . X . 9 x 2 = 1 x . = 1 Slide 19 Slide 20 Slide 21 Slide 22 Slide 23 Our Dear Students: Please revise and study by heart all times tables, ( starting from table 2 till table 9)
