This resource is inside The Hive, along with thousands more, plus powerful digital tools and time-saving systems.

This Teaching & Learning Program is designed for Grade 3 & 4 students.

It includes 5 days of differentiated lesson plans with:

  • Learning Intentions & Success Criteria aligned to NSW and Australian curriculum outcomes

  • Explicit teaching activities (I do)

  • Guided teaching activities (We do)

  • Independent teaching activities (You do)

  • Reflection questions

  • Support and extension activities to target every student in your class

  • 5 x differentiated rotation activities for consolidation and review at the end of each unit of learning

CURRICULUM OUTCOMES

Australian Curriculum:

  • Add and subtract two- and three-digit numbers using efficient written strategies including standard algorithms (AC9M3N04)

NSW Curriculum:

  • Outcomes:

    • Selects and uses mental and written strategies for addition and subtraction involving 2- and 3-digit numbers (MA2-AR-01)

  • Content:

    • Partition, rearrange and regroup numbers to at least 1000 to solve additive problems

      • Use an algorithm with understanding to record addition and subtraction calculations, where efficient, involving 3-digit numbers

      • Recognise how hundreds are exchanged in subtraction algorithms requiring regrouping

      • Recognise when mental strategies would be more efficient than a vertical algorithm for subtraction (Reasons about relations)

      • Solve subtraction questions with missing digits given the difference (Reasons about relations)
