Activity
1. Solve Exercise 1 on Page 109 in Math 3 Textbook
Problem: What is the number?
Guidance: To determine how many times a large number surpasses a smaller one, divide the larger number by the smaller one.
Answer:
2. Solve Exercise 2 on Page 110 in Math 3 Textbook
Problem: What is the number?
a) Calculate how many times a long pencil is longer than a wax crayon.
b) Calculate how many times a long pencil is longer than a thumbtack.
Guidance:
a) To find how many times a long pencil is longer than a wax crayon, divide the length of the pencil by the length of the crayon.
b) To find how many times a long pencil is longer than a thumbtack, divide the length of the pencil by the length of the thumbtack.
Answer:
a) A long pencil is 2 times longer than a wax crayon (10 cm : 5 cm = 2).
b) A long pencil is 5 times longer than a thumbtack (10 cm : 2 cm = 5).

Problem: There are 32 balls arranged in rows and columns as follows:
a) What is the number?
Each row has ? balls.
Each column has ? balls.
b) The number of balls in a row is how many times the number of balls in a column.
Solution:
Step 1: Observe the illustration and count the number of balls in each row and column.
Step 2: To find how many times the number of balls in a row is greater than the number of balls in a column, divide the number of balls in a row by the number of balls in a column.
Answer:
a) Each row has 8 balls.
Each column has 4 balls.
b) The number of balls in a row is 2 times the number of balls in a column. (Because 8 : 4 = 2).

Problem: The large boat carries 24 tourists, and the small boat carries 6 tourists. Ask:
a) How many more tourists does the large boat carry than the small boat?
b) The number of tourists on the large boat is how many times the number of tourists on the small boat?
Solution:
a) The number of tourists the large boat carries more than the small boat = Number of tourists on the large boat - Number of tourists on the small boat.
b) The number of tourists on the large boat is how many times the number of tourists on the small boat = Number of tourists on the large boat : Number of tourists on the small boat.
Answer:
a) The large boat carries more tourists than the small boat:
24 - 6 = 18 (tourists)
b) The number of tourists on the large boat is how many times the number of tourists on the small boat:
24 : 6 = 4 (times)
Answer: a) 18 tourists.
b) 4 times.
