Educational "Adding One Sheet" worksheets with visual aids for early math practice.

Problem Description:

The task involves completing addition sentences by observing the images provided. Each row shows a set of objects, and the goal is to determine the total number of objects when one more object is added.

Solution:

#### First Row: Socks
- The image shows 5 socks.
- One additional sock is shown separately.
- The total number of socks is \( 5 + 1 = 6 \).

So, the number sentence is:
\[
5 + 1 = 6
\]

#### Second Row: Hats
- The image shows 6 hats.
- One additional hat is shown separately.
- The total number of hats is \( 6 + 1 = 7 \).

So, the number sentence is:
\[
6 + 1 = 7
\]

#### Third Row: Hands
- The image shows 6 hands.
- One additional hand is shown separately.
- The total number of hands is \( 6 + 1 = 7 \).

So, the number sentence is:
\[
6 + 1 = 7
\]

Final Answer:

\[
\boxed{5 + 1 = 6, \quad 6 + 1 = 7, \quad 6 + 1 = 7}
\]
