Skill: Identify a whole

The whole is the complete object or collection before it is split into parts. To find it:

1. Look for the outside boundary around everything.
2. Include all the equal parts inside that boundary.
3. Check that all the parts together make the complete object.

Example: A chocolate bar is split into 3 equal pieces.

$$\boxed{\text{piece}}\boxed{\text{piece}}\boxed{\text{piece}}$$

• The outside boundary around all three pieces shows the whole.
• The whole is the entire chocolate bar.
• One small box is one part, not the whole.
• When the 3 equal pieces are put together, they make 1 whole chocolate bar.

So, the answer is: The whole is the entire chocolate bar.
