  2. A part-part-whole model can be used to represent these different ways.
  3. A group of objects can be partitioned into two or more parts.

Keywords

  • Whole - Whole means all of something. Complete.

  • Part - A part is a piece or section of a whole.

  • Partition - Partition means to split up a whole into parts.

  • Part-part-whole model - A part-part-whole model is a pictorial representation that shows the whole and its parts.

Common misconception

When describing the partitioning of a number, children may mix the parts and the whole.

Reinforce the stem sentence, ___ is the whole, ___ is a part and ___ is a part highlighting, the whole and each part using gestures.

In the video, the part-part-whole model has been referred to as a part-whole model. We recommend using part-part-whole when describing additive structures. We use part-whole when describing fractional relationships between a part and a whole.
