While introducing the concept of Addition of Fractions, in class V, Daljeet, a mathematics teacher focuses only on using the standard correct procedure to solve a given problem. She gives many questions to her learners for practice by using the algorithm taught. As a mathematics teacher, Daljeet exhibits

Correct option is B

Relational understanding: This refers to the ability to connect mathematical concepts and see relationships between them. While focusing on a single procedure might involve some basic connections, it doesn't necessarily encourage broader relational understanding.
Instrumental understanding: This refers to the ability to use mathematical procedures effectively and accurately to solve problems. Daljeet's focus on the standard procedure and providing practice questions aligns with this type of understanding.
Understanding of learners' needs: The passage doesn't mention Daljeet tailoring her approach to address specific needs of her learners or gauging their understanding beyond rote application of the procedure.
Understanding of learners' errors: Similarly, the passage doesn't mention Daljeet actively identifying or addressing common errors made by her learners in addition of fractions.
Therefore, while Daljeet might be promoting instrumental understanding through her approach, it lacks elements of the other options mentioned.
