Lesson details
Key learning points
- Drawing a part-part-whole model can help you to understand a mathematical story or equation.
- Moving counters or cubes within a part-part-whole model can help you to understand a mathematical story or equation.
- Describing a problem or equation can help you understand it.
- You can tell a story to represent an equation or completed part-part-whole model.
Keywords
Equation - An equation says that two things are equal. It will have an equal sign ( = ) and the expression on either side will have the same value.
Part-part-whole model - This shows how the whole can be partitioned into parts and recombined. It demonstrates the equality between the parts and the whole.
Common misconception
When using part-part-whole models, children may put counters in the parts and whole simultaneously.
Work practically, moving counters to show we can partition the whole into parts and recombine the parts to make the whole again.
