Why this why now
This unit allows pupils to deepen their understanding of the relationship between addition and subtraction. The part-part-whole structure is used to identify what is known and unknown in a given context or problem. Pupils generalize about how to find a missing part or whole using addition and subtraction. They have the opportunity to apply this understanding in different contexts including statistics.
Prior knowledge requirements
- Know the inverse relationship between addition and subtraction
- Use number facts to solve missing number problems
- Recognise equivalent expressions in different forms
- Interpret adn present data using bar charts, pictograms and tables
