Notes for Parents/Teachers

Topics Covered:

  • Whole Numbers (up to 100): counting, place value, comparing
  • Number Patterns (skip counting by 5s)

  • Time (reading o'clock)
  • Shapes (2D shape properties)
  • Money (counting coins)
  • Picture Graphs (simple interpretation)

Common Mistakes to Watch For:

  1. Place value: confusing "digit" with "value"
  2. Comparison: not comparing from the highest place value
  3. Word problems: not reading carefully for "more than" vs "left"
  4. Picture graphs: miscounting symbols

Suggested Follow-up:

  • Practice place value with physical objects (base-10 blocks)
  • Use number lines for addition and subtraction
  • Real-life money practice with coins
