A question that doesn't have a single answer or a single way to find the answer is known as an open-ended question.
The question given above by the teacher is also open-ended as it doesn't have a single answer
- Task 1 has many answers like 28 + 50 = 78 , 55 + 23 =78 , 10 + 68 = 78 etc.
- Task 2 also has many answers like 50 - 16 = 34, 74 -40 = 34, 100 - 66 = 34 etc.
Open-ended questions in math:
- Enhance creativity in students.
- Assess the students on mental computation and estimation skills.
- Allow students to solve in different ways according to their understanding.
- Avoid rote memorization and enhance divergent thinking.
Hence the task in the above question would assess the students on mental computation and estimation skills.
