🌟 NEP 2020 Competency-Based Case Study

Orchard Mango Harvest Case Study

Grandpa gives Anaya 5 ripe yellow mangoes and gives Kabir 3 ripe yellow mangoes in cane baskets.

Analytical Task: Who has more mangoes and by how many? If Anaya eats all 5 of her mangoes, how many mangoes remain in her basket?
Evaluation & Model Answer:
1. Anaya has 5 and Kabir has 3. Since 5 > 3, Anaya has more mangoes.
2. Difference = 5 - 3 = 2 more mangoes.
3. If Anaya eats all 5, her basket has 5 - 5 = 0 (Zero) mangoes left.
Rubric: 1 M for comparison + 1 M for difference + 1 M for zero calculation
