Step 1: state what changes and what stays fixed
After the first reading, ask the student to describe the situation without using calculations. On the second reading, identify the quantities, units and relationships. Phrases such as ‘the remainder’, ‘twice as many’ or ‘after giving away’ describe how quantities are connected.
Writing a one-line question in the student’s own words can prevent work on the wrong target. The sentence should name what must be found and the unit expected.
Step 2: represent the relationship
A bar model is useful for some part-whole and comparison problems, but it is not the only representation. A table may suit repeated changes, a diagram may suit geometry, and an equation may be clearer when the unknown relationship is already understood.
The representation should reduce complexity. If it adds more labels than the original question, pause and simplify it.
A clear representation should follow these principles:
- Label units and meaningful quantities.
- Use consistent parts or scales in models.
- Mark the unknown clearly.
- Avoid decorating the diagram with unused information.
Step 3: solve one relationship at a time
For multi-step questions, write a short purpose beside an intermediate result, such as ‘amount left’ or ‘value of one part’. This keeps the chain of reasoning visible and makes checking easier.
If the student is stuck, ask which quantity would make the final step possible. Working backwards from that need often reveals the next useful calculation without giving away the whole solution.
Step 4: check meaning, scale and units
Substitute the answer into the story. Is it larger or smaller than the starting amount as expected? Does the total match the stated relationship? Are people, dollars, centimetres or another unit required?
An estimate can catch misplaced operations. The exact result may be complex, but its approximate size should usually make sense.
