Use efficient strategies and common measure conversions to solve problems in a range of contexts
Lesson details
Learning outcome
I can use efficient strategies and common measure conversions to solve problems in a range of contexts.
Key learning points
- Use known facts to solve problems involving measures.
- Use informal methods such as partitioning and bridging to solve problems involving measures.
- Convert between units of measure to simplify problems.
Keywords
Convert - To change a value from one form to another, such as converting 1 m into 1,000 mm
Common misconception
Pupils may need support to identify the operation(s) involved in solving a problem and when a problem is presented with mixed units and it is necessary to convert one of them.
Read the problems aloud. Ensure that children identify the operation(s) involved and see this as a clear step in solving the problem. Emphasise the units of measure so that attention is drawn to them and they identify whether conversion is needed.
Teacher tip
The problems are presented first with no values to encourage children to think about the problem, identify what is known and unknown and represent the situation in a bar model first. This may need explaining to children. There may be some who need a prompt for the unit conversions.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
