Solve problems involving converting units in different contexts
Lesson details
Learning outcome
You can solve problems involving converting units in different contexts
Key learning points
- Use known units of measure and their equivalents to solve problems
Keywords
Convert - Change a value or expression from one form to another, such as grams into kilograms.
Common misconception
The most common mistake pupils will make when faced with these sorts of questions is not taking into account the unit conversion that needs to take place if the units of measure are mixed.
You may wish to consider drawing extra attention to the fact that the units of measure are different when presenting the Practice tasks, for example highlighting them in different colours if appropriate.
Teacher tip
The lesson incorporates a variety of calculation types: those which should be known facts such as times tables, those which are relatively easy to calculate and can be worked out mentally such as multiplying by 10, and those which require a written strategy. You may wish to use further modelling.
