Worksheet Problems 1-3: Basic Word Problems
1 Sharing Apples Problem
Worksheet Problem 1
Sarah has 8 apples. She wants to share them equally between 2 friends. Can she do this without any apples left over? Is 8 odd or even?
Problem Analysis:

This problem asks us to determine if 8 can be divided equally between 2 people and identify if 8 is odd or even.

Definition:

Even numbers: Numbers that can be divided by 2 without remainder (0, 2, 4, 6, 8...)

Odd numbers: Numbers that cannot be divided by 2 without remainder (1, 3, 5, 7, 9...)

Given Information:

• Sarah has 8 apples

• She wants to share equally between 2 friends

• Question: Will there be any apples left over?

4 each, no remainder
Solution Steps:
  1. Step 1: Divide 8 apples by 2 friends: 8 ÷ 2 = 4
  2. Step 2: Check if there's a remainder: 8 ÷ 2 = 4 remainder 0
  3. Step 3: Since there's no remainder, Sarah can share equally
  4. Step 4: Since 8 divides evenly by 2, 8 is an even number
Step 1: Division

8 ÷ 2 = 4, with no remainder

Step 2: Verification

4 × 2 = 8, confirming the division is exact

Step 3: Classification

Since 8 can be divided by 2 without remainder, it's an even number

Yes, Sarah can share 8 apples equally between 2 friends (4 each). 8 is even.
Final answer:

Yes, Sarah can share the 8 apples equally between 2 friends. Each friend gets 4 apples with none left over. The number 8 is an even number.

Applied rules:

• Division test: Even numbers divide evenly by 2

• Remainder test: No remainder indicates an even number

• Equal sharing: Even numbers can be shared equally between 2

2 Seating Arrangement Problem
Worksheet Problem 2
There are 7 children in a classroom. The teacher wants to seat them in pairs. How many children will not have a partner? Is 7 odd or even?
Problem Analysis:

This problem asks us to determine how many children won't have a partner when 7 children are seated in pairs, and identify if 7 is odd or even.

Definition:

Pairing concept: Even numbers can be grouped into pairs with nothing left over

Remainder concept: Odd numbers have one item left over when pairing

Given Information:

• 7 children total

• Seating in pairs

• Question: How many children will not have a partner?

Solution Steps:
  1. Step 1: Try to form pairs: (child1, child2), (child3, child4), (child5, child6)
  2. Step 2: Count the remaining children: 1 child left over
  3. Step 3: Since there's one child without a partner, 7 is odd
  4. Step 4: Verify with division: 7 ÷ 2 = 3 remainder 1
Step 1: Form pairs

(👧, 👦), (👧, 👦), (👧, 👦) with 1 👧 left over

Step 2: Count remaining

3 pairs formed, 1 child without a partner

Step 3: Classification

Since there's a remainder when pairing, 7 is an odd number

1 child will not have a partner. 7 is odd.
Final answer:

1 child will not have a partner when seating 7 children in pairs. The number 7 is an odd number because it leaves a remainder of 1 when divided by 2.

Applied rules:

• Pairing test: Even numbers form complete pairs

• Remainder test: Odd numbers leave a remainder of 1 when divided by 2

• Visual representation: Pairing helps understand the concept concretely

3 Pattern Recognition Problem
Worksheet Problem 3
The school is numbering lockers. The even-numbered lockers will be blue and odd-numbered lockers will be red. Which color will locker number 15 be? Explain your reasoning.
Problem Analysis:

This problem asks us to determine if 15 is odd or even to decide the color of locker number 15.

Definition:

Even number pattern: Counting by 2s starting from 2 (2, 4, 6, 8, 10...)

Odd number pattern: Counting by 2s starting from 1 (1, 3, 5, 7, 9...)

Given Information:

• Even-numbered lockers are blue

• Odd-numbered lockers are red

• Question: What color is locker number 15?

Solution Steps:
  1. Step 1: Look at the last digit of 15: it's 5
  2. Step 2: Apply the last digit rule: 5 is odd
  3. Step 3: According to the pattern, odd numbers are red
  4. Step 4: Verify with division: 15 ÷ 2 = 7 remainder 1
Step 1: Check last digit

Locker number 15 ends in 5, which is an odd digit

Step 2: Apply rule

Since 15 ends in an odd digit, it's an odd number

Step 3: Determine color

According to the pattern, odd-numbered lockers are red

Locker 15 will be red because 15 is odd.
Final answer:

Locker number 15 will be red because 15 is an odd number. Since it ends in 5 (an odd digit), and follows the alternating pattern of odd, even, odd, even..., it falls in the odd category.

Applied rules:

• Last digit rule: Odd numbers end in 1, 3, 5, 7, or 9

• Pattern recognition: Numbers alternate between odd and even

• Division test: Odd numbers leave a remainder of 1 when divided by 2
