Key lesson features
- Mastering mathematical understanding
- Mastering mathematical thinking
- Mastering mathematical language
What does a Mathematics Mastery look like at Sudbury Primary School?
- 6 parts (Do Now, New Learning, Talk Task, Developed learning, Independent Task, Plenary)
- Concrete objects (Concrete, pictorial, abstract)
- Partner talk tasks
- Use of full sentences
- Transitions
- Maths meetings
- A maths lesson is made up of 6 parts. Some are quick 5 minute refreshers, practising a skills, other parts are longer and teaching the children something new and also include opportunities to have a go with a partner. We have a CPA approach to maths – simply concrete meaning actual objects used (cubes, beadstring, dienes/place value blocks etc.), Pictorial – how you can draw the maths and ABSTRACT – the numbers and symbols.

The Big Picture gives conceptual understanding in real life situations – why we are learning the maths?
Examples of unit themes for each year group. Year 1 Fairy tales (Goldilocks, Red Riding Hood), Year 2 jobs (builder, teacher, tailor), Year 3 famous landmarks (Millennium stadium, Blackpool pleasure beach), year 4 countries and continents (Paris, map of the world…)
Progression in calculation at Sudbury Primary School
Addition:
- Joining two groups and then recounting all objects using one-to-one correspondence
- Counting on
- Part-part-whole
- Regrouping ten ones to make ten
- ‘Make ten’ strategy
- Adding three single digit numbers (make ten first)
- ‘Make ten’ strategy
- Adding three single digit numbers (make ten first)
- Partitioning to add (no regrouping)
- Introducing column method for addition, regrouping only
- Partitioning one number, then adding tens and ones
- Rounding one number, then adding the tens and taking away extra ones
- Partitioning to add without regrouping
- Column method with regrouping
- Make ten strategy
- Using known facts
Subtraction:
- Using known facts - Pictures and crossing out or circling. Pictorial and abstract and objects/concrete can be used as well.
- Taking away from the ones
- Counting back
- Make ten strategy
- Regroup a ten into 10 ones
- Taking away from the tens
- Partitioning to subtract without regrouping
- Column method with regrouping
- Subtracting tens and ones
- Subtracting tens and adding extra ones
- Partitioning to subtract without regrouping
- Column method with regrouping
- Bridging through ten
Multiplication:
- Skip counting in multiples of 2, 5, 10 from zero
- Solve multiplications using repeated addition
- Skip counting in multiples of 2, 3, 4, 5, 10 from 0
- Multiplication is commutative
- Bar modelling to represent the parts, the whole and the number of parts in multiplication word problems
- Use of part-part-whole model to establish the inverse relationship between multiplication and division
- Doubling to derive new multiplication facts
- Ten times bigger
- Multiplying by 10, 100 and 1000
- Multiplication of 2-digit numbers with partitioning (no regrouping)
- Multiplication of 2-digit numbers with partitioning (regrouping)
- Show with a video at the end alongside division
- Short multiplication of 3-digit number by 1-digit number
Division:
- Sharing objects into groups
- Division as sharing
- Use of part-part-whole model to represent division equations and to emphasise the relationship between division and multiplication
- Division by partitioning and sharing into equal groups with no regrouping required
