Year 2 Maths Autumn Block 2: Addition and Subtraction

Autumn Block 2: Addition and Subtraction Within 100 (Year 2)

Develop secure calculation skills with this Year 2 addition and subtraction within 100 unit, aligned with the White Rose small steps and mapped to the Year 2 National Curriculum. This block helps pupils build fluency with number bonds, related facts and efficient calculation strategies before applying their understanding to increasingly challenging addition and subtraction problems.

Pupils revisit fact families and number bonds before exploring addition and subtraction with ones and tens, bonds to 100 and strategies such as making ten. They then progress to two-digit calculations, including addition and subtraction across ten, helping them develop confidence and accuracy when working within 100.

Week 5 small steps

  • Fact families to 20
  • Check calculations
  • Compare number sentences
  • Number bonds within 10
  • Related facts (ones and tens)

Week 6 small steps

  • Bonds to 100
  • Add and subtract ones
  • Ten more and ten less
  • Add and subtract tens
  • Add by making ten

Week 7 small steps

  • Add a 2-digit and 1-digit number (crossing ten)
  • Subtract (crossing ten)
  • Subtract a 1-digit from a 2-digit number (crossing ten)

Week 8 small steps

  • Add two 2-digit numbers (not crossing ten)
  • Add two 2-digit numbers (crossing ten)
  • Subtract two 2-digit numbers (not crossing ten)
  • Subtract two 2-digit numbers (crossing ten)

Week 9 small steps

  • Find and make number bonds within 20
  • Number bonds to 100 (tens and ones)
  • Add three 1-digit numbers

National Curriculum objectives

  • Solve problems with addition and subtraction using concrete objects and pictorial representations
  • Recall and use addition and subtraction facts to 20 fluently, and derive and use related facts up to 100
  • Add and subtract a two-digit number and ones
  • Add and subtract a two-digit number and tens
  • Add and subtract two two-digit numbers
  • Add three one-digit numbers
  • Understand that addition is commutative but subtraction is not
