Stockbridge Counts – Combining & partitioning & place value

OUR CURRENT FOCUS ACROSS THE SCHOOL IS COMBINING & PARTITIONING AND PLACE VALUE

From Monday 20th February to Friday 31st March

What will this look like for my child?

Combining & partitioning and place value within Early Level (Nursery and P1, but earlier or later for some)

Make finger patterns:

  • To show numbers 1 to 5 using one hand
  • To show double patterns for 1 to 5 (two hands)
  • To show doubles plus one patterns (two hands e.g. double 3 plus 1)
  • To partition numbers (e.g. “Make 6 on your fingers. Can you make it another way?”)
  • To partition 10 (e.g. 9 fingers up and 1 down shows 9 + 1 = 10

Recognise flashed patterns (domino and random)

  • Explore partitions of numbers through dot patterns

Combining & partitioning and place value within First Level (P2, P3 & P4, but earlier or later for some)

Combining and partitioning

  • Partition numbers up to ten into number bonds (e.g. know that 5 = 1 + 4 and so on)
  • Use number bond knowledge to say what number gets us to/from a decade (e.g. 34 + ? = 40, 54 – ? = 50)

Place value

Split a number containing tens and units

  • In a standard way e.g. (36 is 3 tens and 6 units)
  • In a non-standard way (e.g. 36 is 2 tens and 16 units)

Demonstrate how the value of a digit depends on where it is placed e.g. the 3 in 236 means 3 tens or 30

Split a number into its place value parts e.g. 364 = 300 + 60 + 4 (numbers up to 1000)

Combining & partitioning and place value within Second Level (P5, P6 & P7, but earlier or later for some)

Combining and partitioning

  • Partition 100 (e.g. 23 + ? = 100) to help with percentage calculations
  • Partition 1000

Place value

  • Demonstrate how the value of a digit depends on where it is placed (numbers up to 1 million)
  • Split a number into its place value parts
    • In the range 1 to 1000000
    • For decimals up to 2 decimal places (e.g. 2.5 is 2 and 5 tenths)
  • Split a decimal up in a non-standard way (e.g. 3.2 can be 2 and 12 tenths)
