Solve problems with numbers with up to 3 decimal places
Lesson details
Learning outcome
I can solve problems with numbers with up to 3 decimal places
Key learning points
- Apply known facts and place value to solve problems involving up to 3 decimal places.
- Extend column addition and subtraction to include numbers with up to 3 decimal places.
- Use number facts to 10 to bridge through ones, tenths and hundredths.
Keywords
Represent - A representation is a way of showing a mathematical idea. Concrete objects, pictures and symbols can all be used to represent mathematics.
Operation - A mathematical process such as addition, subtraction, multiplication or division can be described as an operation.
Efficient - An efficient strategy is a way of solving a problem that is accurate and can be done more quickly than others.
Common misconception
Pupils may look to adopt a formal written strategy straight away when this is not necessary.
Share different strategies utilised by pupils within the lesson and compare these to expand pupils' understanding of efficiency.
Teacher tip
Give plenty of time for pupils to represent problems with bar models without an emphasis on finding the answer. This will support pupils to access the maths through the worded contexts and enable them to identify appropriate operations to help solve.
