Notes for Parents/Teachers

Topics Covered:

  • Whole Numbers (up to 1000): Place value, comparing, ordering, odd/even
  • Number Patterns: Skip counting by 50
  • Addition & Subtraction: 3-digit with regrouping/borrowing
  • Multiplication & Division: Tables 2-5, 10; remainders
  • Fractions: Parts of whole, comparing unit fractions, comparing like fractions
  • Money: Decimal notation, addition, subtraction, change
  • Measurement: Length (m and cm conversion)
  • 3D Shapes: Properties of cube
  • Picture Graphs: Reading scaled graphs (scale of 2)

Common Mistakes to Watch For:

  1. Place value: confusing hundreds/tens/ones values
  2. Subtraction: borrowing across zeros
  3. Fractions: thinking bigger denominator = bigger fraction
  4. Money: decimal point placement
  5. Picture graphs: forgetting to apply the scale

Progression from P1:

  • Numbers extended to 1000
  • More complex addition/subtraction (3-digit with regrouping)
  • Division with remainders introduced
  • Fractions introduced (comparison and like fractions)
  • Money in decimal form
  • Scaled picture graphs

Suggested Follow-up:

  • Practice place value with manipulatives
  • Use real money for shopping problems
  • Draw fraction bars to visualize comparisons
  • Create own picture graphs with different scales
