Q2 First guess the answer and then calculate:
(a) A flower has five petals. A bunch of flowers has 13 flowers. How many petals are there in the
bunch?
(b) A book has 64 pages. What will be the total number of pages in 8 such books?
(c) Students stand in rows in the assembly. There are six rows of students. Each row has 17 students.
How many students are there?
(d) A design has 3 flowers in it. A piece of cloth has 17 such designs. How many flowers will be on the
cloth?
(a) Number of flowers in one bunch = 13 Each flower has 5 petals. Total petals in the bunch = 13×5
Adding the number in the boxes:
So, 13×5 = 65
Thus, there are 65 petals in a bunch.
(b) Number of books = 8 Each book has 64 pages. Total pages in 8 books = 8×64
Adding the number in the boxes:
So, 8×64 = 512
There are 512 pages in all the 8 books.
(c) Number of rows in assembly = 6 Each row has 17 students. Total students in 6 rows = 6×17
So, 8×64 = 512
There are 512 pages in all the 8 books.
(d) Number of rows in assembly = 6 Each row has 17 students. Total students in 6 rows = 6×17

Q2 Multiplication Patterns
9×1=9
9 × 2 = 18 1 + 8 = 9
9 × 3 = 27 2 + 7 = 9
9 × 4 = 36 3 + 6 = 9
9 × 5 = 45 4 + 5 = 9
9 × __ = __ __ + __ = __
9 × __ = __ __ + __ = __
9 × 8 = __ __ + __ = __
Did you see the pattern in the 9 times table? What numbers are adding up to 9?
Answer. The multiplication pattern is explained in the table given below. Ones digit of all the numbers
are in descending order i.e. 8, 7, 6, 5, 4, 3, 2, 1. And, the tens digit are the numbers in ascending order
i.e. 1, 2, 3, 4, 5, 6, 7, 8. Ones digit number and tens digit number adds to 9.
9×1=9
9 × 2 = 18 1 + 8 = 9
9 × 3 = 27 2 + 7 = 9
9 × 4 = 36 3 + 6 = 9
9 × 5 = 45 4 + 5 = 9
9 × 6 = 54 5 + 4 = 9
9 × 7 = 63 6 + 3 = 9
9 × 8 = 72 7 + 2 = 9
9 × 9 = 81 8 + 1 = 9
