Number beads worksheet for learning counting and number identification.

Problem Description:

The task involves analyzing a series of number bead strings and determining the numbers represented by the positions of the yellow beads. Each row represents a different number range, and the yellow beads indicate specific values within that range.

Solution Approach:

1. Understand the Bead System:
- Each string of beads represents a sequence of numbers.
- Blue beads represent intermediate steps or placeholders.
- Yellow beads mark the specific numbers we need to identify.

2. Analyze Each Row:
- For each row, identify the position of the yellow beads relative to the given number range.
- Write down the corresponding numbers in the labels provided below each row.

3. Step-by-Step Analysis:

#### Row 1: Range 10 to 40
- Positions of yellow beads:
- First yellow bead is at position 25.
- Second yellow bead is at position 35.
- Labels: Write "25" and "35".

#### Row 2: Range 50 to 80
- Positions of yellow beads:
- First yellow bead is at position 65.
- Second yellow bead is at position 75.
- Labels: Write "65" and "75".

#### Row 3: Range 40 to 70
- Positions of yellow beads:
- First yellow bead is at position 55.
- Second yellow bead is at position 65.
- Labels: Write "55" and "65".

#### Row 4: Range 20 to 50
- Positions of yellow beads:
- First yellow bead is at position 30.
- Second yellow bead is at position 40.
- Labels: Write "30" and "40".

#### Row 5: Range 80 to 110
- Positions of yellow beads:
- First yellow bead is at position 90.
- Second yellow bead is at position 100.
- Labels: Write "90" and "100".

#### Row 6: Range 10 to 40
- Positions of yellow beads:
- First yellow bead is at position 15.
- Second yellow bead is at position 25.
- Labels: Write "15" and "25".

Final Answer:

Write the following numbers in the respective labels:

1. Row 1: 25, 35
2. Row 2: 65, 75
3. Row 3: 55, 65
4. Row 4: 30, 40
5. Row 5: 90, 100
6. Row 6: 15, 25

\boxed{
\begin{array}{c}
\text{Row 1: 25, 35} \\
\text{Row 2: 65, 75} \\
\text{Row 3: 55, 65} \\
\text{Row 4: 30, 40} \\
\text{Row 5: 90, 100} \\
\text{Row 6: 15, 25}
\end{array}
