Lesson details
Key learning points
- The teens numbers can be represented as ten and a bit.
- We can solve addition and subtraction problems with the ones part or tens part missing.
- A part-part whole model can help to represent the missing whole or missing parts.
Keywords
Partition - The act of splitting an object or value down into smaller parts.
Whole - All of a group or number.
Part - A piece or section of the whole.
Common misconception
Pupils do not connect a known partition of a teen number e.g. 16 is 1 ten and 6 ones to a subtraction or addition context and therefore use a less efficient strategy.
Practical experiences using a group of 10 and ones are key to supporting understanding that the partitioning structure can work for different contexts.
