Solve problems using a bar model to represent a whole partitioned into two parts
I can solve problems using a bar model to partition a number into two parts.
Lesson details
Key learning points
- Partitioning of numbers to five can be represented using the bar model.
- The bar model and the part-part-whole diagram can be used to represent stories.
- Systematic thinking can be used to ensure all possible responses to a problem can be found.
Common misconception
As before, children may confuse the whole and the parts, or add them all up to find the total.
Place objects in each part of the bar model and combine them to make the whole, or starting within the whole, partition them into the parts.
Keywords
Partition - Partition is to split a whole up into parts.
Combine - Combine means to put parts together to make a whole.
Bar model - A bar model is a pictorial representation of a problem where bars are used to represent the whole and the parts.
