Skip Counting by 100s Worksheets | 2nd Grade Math Activities - Free Printable

Problem Description:

The task involves skip counting by 100 and filling in the missing numbers in a grid. The goal is to complete the sequence by adding 100 to each number in the row.

Solution Approach:

1. Understand Skip Counting by 100:
- Skip counting by 100 means adding 100 to each subsequent number.
- For example, starting from 100: \(100, 200, 300, 400, \ldots\).

2. Analyze the Grid:
- The grid contains rows and columns of numbers.
- Each row follows a pattern where consecutive numbers increase by 100.
- Missing numbers need to be filled in based on this pattern.

3. Fill in the Missing Numbers:
- Identify the missing numbers in each row by adding 100 to the previous number or subtracting 100 from the next number.

Step-by-Step Solution:

#### Row 1:
- Given: \(100, 200, \_, 400, 500, \_\)
- Missing numbers:
- Between 200 and 400: \(200 + 100 = 300\)
- After 500: \(500 + 100 = 600\)
- Filled row: \(100, 200, 300, 400, 500, 600\)

#### Row 2:
- Given: \(300, 400, 500, \_, 700, \_\)
- Missing numbers:
- Between 500 and 700: \(500 + 100 = 600\)
- After 700: \(700 + 100 = 800\)
- Filled row: \(300, 400, 500, 600, 700, 800\)

#### Row 3:
- Given: \(500, 600, \_, 800, 900, \_\)
- Missing numbers:
- Between 600 and 800: \(600 + 100 = 700\)
- After 900: \(900 + 100 = 1000\)
- Filled row: \(500, 600, 700, 800, 900, 1000\)

#### Row 4:
- Given: \(250, \_, 450, 550, 650, 750\)
- Missing numbers:
- Between 250 and 450: \(250 + 100 = 350\)
- Filled row: \(250, 350, 450, 550, 650, 750\)

#### Row 5:
- Given: \(420, 520, 620, \_, 820, 920\)
- Missing numbers:
- Between 620 and 820: \(620 + 100 = 720\)
- Filled row: \(420, 520, 620, 720, 820, 920\)

#### Row 6:
- Given: \(80, 180, \_, 380, 480, 580\)
- Missing numbers:
- Between 180 and 380: \(180 + 100 = 280\)
- Filled row: \(80, 180, 280, 380, 480, 580\)

Final Answer:

The completed grid is:

\[
\begin{array}{cccccc}
100 & 200 & 300 & 400 & 500 & 600 \\
300 & 400 & 500 & 600 & 700 & 800 \\
500 & 600 & 700 & 800 & 900 & 1000 \\
250 & 350 & 450 & 550 & 650 & 750 \\
420 & 520 & 620 & 720 & 820 & 920 \\
80 & 180 & 280 & 380 & 480 & 580 \\
\end{array}
\]

\boxed{
\begin{array}{cccccc}
100 & 200 & 300 & 400 & 500 & 600 \\
300 & 400 & 500 & 600 & 700 & 800 \\
500 & 600 & 700 & 800 & 900 & 1000 \\
250 & 350 & 450 & 550 & 650 & 750 \\
420 & 520 & 620 & 720 & 820 & 920 \\
80 & 180 & 280 & 380 & 480 & 580 \\
\end{array}
}
