Lesson details
Key learning points
- Visualising and representing problems as bar models (by identifying the parts and whole) helps us to solve problems..
- The bar model helps us to understand the structure of the maths and to form a calculation to help solve the problem.
- If parts are unequal, we can use additive relationships; if parts are equal, we can use multiplicative relationships.
- Number facts can be used when solving problems involving mass.
Keywords
Bar model - A bar model is a pictorial representation of a problem where bars are used to represent the known and unknown quantities.
Whole - The whole is all of something. It is complete.
Part - A part is some but not all of something. It is an amount or section which, when combined with others, makes up the whole.
Volume - Volume is the amount of space that an object takes up. In this case, the specific amount of liquid in a container. It can be measured in ml.
Common misconception
Children may misidentify the parts or wholes in a problem.
Children should be encouraged to visualise the problem to help them identify the parts and whole.
