Informal and mental strategies for adding and subtracting two 3-digit numbers

10 lessons

Threads

  • Number: Addition and Subtraction
  • Ratio and Proportion

This unit develops mental strategies applied to numbers bridging 100 and applies them to adding and subtracting 3-digit numbers. Pupils consider how to partition numbers to enable them to bridge multiples of 10 and 100. They also use number lines to find the difference and make decisions on which is the most efficient strategy to add or subtracts pairs of 3-digit numbers. This consolidation of mental and informal strategies prepares pupils for the introduction of more formal strategies in later units.

  1. Add two 3-digit numbers using partitioning
  2. Add two 3-digit numbers using adjusting strategies
  3. Add 2 and 3-digit numbers by redistributing
  4. Choose the most efficient strategy to add two 3-digit numbers
  5. Subtract 2 or 3-digit numbers using partitioning and bridging a multiple of 10
  6. Subtract a pair of 2-digit numbers by finding the difference
  7. Subtract 3-digit multiples of 10 by finding the difference between them
  8. Choose the most efficient strategy to subtract from a 3-digit number
  9. Use addition and subtraction to solve problems involving bar charts, pictograms and tables
  10. Use addition and subtraction to solve problems in different contexts
