Lesson details
Key learning points
- Word problems can be represented in a bar model by identifying the parts and the whole.
- To find the whole, we need to add the parts together.
- To find a part, we need to subtract the part we know from the whole.
- If the units are different, they need to be converted to the same unit.
Keywords
Bar model - A pictorial representation of a problem where bars are used to represent the known and unknown quantities.
Part - Some but not all of something. It is an amount or section which, when combined with others, makes up the whole.
Whole - All of something. It is complete.
Common misconception
Converting between units; interpreting a word problem; confusing parts and wholes.
When representing as a bar model, visualise the problem to help determine what the parts are and what the whole is.
