Key messages

Number sense is about having a competency with numbers that is based on understanding rather than reliant on memorisation or

algorithms

Number sense can be taught and developed with all

pupils in the class

Carefully crafted number talks are a powerful teaching

and learning strategy to develop number sense

Workshop 1

• Develop number sense through Number Talks and use of models (including Ten Frames and Dot Patterns)

• Develop fluency within ten

• Subitising

• Making tens

Workshop 2

• Develop number sense through Number Talks and use of models (including Empty Number Line and Hundred Square)

• Explore mental strategies for addition and subtraction

• Explore assessment and recording

Benefits for Pupils of Sharing and Discussion of Computation Strategies

• Clarify their own thinking

• Consider and test each other’s strategies to see if they are mathematically logical

• Investigate and apply mathematical relationships

• Build a repertoire of efficient strategies

• Make decisions about choosing efficient strategies for specific problems

What do we do to help them currently?

What else could we do to support their learning?
