Problem 1:

Anna bought 4 red crayons and 2 blue crayons. How many crayons did Anna buy in all?

- Given:
- Red crayons: 4
- Blue crayons: 2

- Question: Total number of crayons Anna bought.

- Solution:
To find the total, we add the number of red crayons and blue crayons:
\( 4 + 2 = 6 \)

- Using Fingers:
- Extend 4 fingers on one hand to represent the red crayons.
- Extend 2 fingers on the other hand to represent the blue crayons.
- Count all the extended fingers together: \( 4 + 2 = 6 \).

- Answer:
\[
\boxed{4 + 2 = 6}
\]

Problem 2:

Sam had 7 pencils. He gave 3 pencils to Ben. How many pencils are left with Sam?

- Given:
- Initial pencils Sam had: 7
- Pencils given to Ben: 3

- Question: Number of pencils left with Sam.

- Solution:
To find the remaining pencils, we subtract the number of pencils given away from the initial number:
\( 7 - 3 = 4 \)

- Using Fingers:
- Extend 7 fingers on both hands to represent the initial pencils.
- Fold down 3 fingers to represent the pencils given to Ben.
- Count the remaining extended fingers: \( 7 - 3 = 4 \).

- Answer:
\[
\boxed{7 - 3 = 4}
\]

Problem 3:

Mia bought 8 gifts. 2 for her friends and the rest for her family. How many gifts did Mia buy for her family?

- Given:
- Total gifts bought: 8
- Gifts for friends: 2

- Question: Number of gifts for her family.

- Solution:
To find the number of gifts for her family, we subtract the number of gifts for friends from the total:
\( 8 - 2 = 6 \)

- Using Fingers:
- Extend 8 fingers on both hands to represent the total gifts.
- Fold down 2 fingers to represent the gifts for friends.
- Count the remaining extended fingers: \( 8 - 2 = 6 \).

- Answer:
\[
\boxed{8 - 2 = 6}
\]

Problem 4:

Ron has 7 oranges and 3 apples. How many fruits does Ron have in all?

- Given:
- Oranges: 7
- Apples: 3

- Question: Total number of fruits Ron has.

- Solution:
To find the total, we add the number of oranges and apples:
\( 7 + 3 = 10 \)

- Using Fingers:
- Extend 7 fingers on one hand to represent the oranges.
- Extend 3 fingers on the other hand to represent the apples.
- Count all the extended fingers together: \( 7 + 3 = 10 \).

- Answer:
\[
\boxed{7 + 3 = 10}
\]

Final Answers:

1. \( \boxed{4 + 2 = 6} \)
2. \( \boxed{7 - 3 = 4} \)
3. \( \boxed{8 - 2 = 6} \)
4. \( \boxed{7 + 3 = 10} \)

Explanation of Using Fingers:

Finger counting is a simple and effective method for young learners to visualize addition and subtraction:
- For addition, extend the fingers corresponding to each number and count all the extended fingers.
- For subtraction, start with the total number of fingers extended and fold down the fingers corresponding to the number being subtracted, then count the remaining extended fingers.

This method helps build a foundational understanding of arithmetic operations.
