The image you uploaded appears to be a worksheet focused on
column addition and subtraction using visual aids (dots or counters). The tasks involve calculating the total number of dots in each column and writing the result. Below, I will explain how to solve these problems step by step.
---
General Approach
1.
Identify the Columns: Each problem is divided into columns, with dots representing numbers.
2.
Count the Dots in Each Column: Count the number of dots in each column separately.
3.
Perform Addition or Subtraction: Depending on whether the operation is addition (+) or subtraction (−), calculate the result.
4.
Write the Answer: Write the final answer in the provided space.

Detailed Explanation for Each Type of Problem
####
1. Column Addition
-
Step 1: Identify the columns and count the dots in each column.
-
Step 2: Add the numbers together.
-
Step 3: Write the sum in the provided space.
Example:
- Suppose one problem has two columns:
- First column: 5 dots
- Second column: 3 dots
- Calculation: \( 5 + 3 = 8 \)
- Write the answer:
8
####
2. Column Subtraction
-
Step 1: Identify the columns and count the dots in each column.
-
Step 2: Subtract the smaller number from the larger number.
-
Step 3: Write the difference in the provided space.
Example:
- Suppose one problem has two columns:
- First column: 7 dots
- Second column: 4 dots
- Calculation: \( 7 - 4 = 3 \)
- Write the answer:
3
####
3. Mixed Problems
- Some problems may involve multiple columns or mixed operations. Follow the same steps as above but ensure you handle each column correctly.
