Lesson details

Key learning points

Use a variety of contexts to show the whole group partitioned into 2 clearly identifiable parts.
Describe the parts and wholes in full sentences .
A whole group of objects can be composed of 2 or more parts.
Use a part-part-whole diagram to represent the two parts and the whole.
Recognise the whole and the two parts are the same quantity.

Common misconception

When using the part-whole model, children may think that the whole is also one of the parts.

When using the part-whole model, move the objects out of the whole into the parts, and replace the whole with a number.

Keywords

Whole - All of something. Complete.
Part - A piece of section of a whole.
Split - To break up a whole into parts.
Partition - To break up a whole into parts.
Part-part-whole - A pictorial representation that shows the whole and its parts.

When using the part-whole model we need to clearly show that the whole is partitioned into the parts and is not included as one of the parts. For each example, repeatedly move the objects back and forth to represent splitting /combining of the parts
