Maths Mastery

 

 

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
