Teaching Notes
First fraction operation! Conceptually intuitive when denominators match: pieces are same size, just add how many you have. 1/4 + 2/4 means '1 fourth plus 2 more fourths = 3 fourths.' Visual models make this concrete. KEY MISCONCEPTION TO PREVENT: Do NOT add denominators! Denominator names the piece size, doesn't change when combining. Use language: 'We have 3 fourths total, not 3 eighths!'
Vocabulary
Common Mistakes
- Adding both numerators AND denominators (1/4 + 2/4 = 3/8)
