Lateral Problem Solving

Eggs in a basket

How could it be that an egg is left in the basket and three people each take an egg?

What does it mean to say that each person takes an egg?

Could all three people take an egg leaving one in the basket?

Act it out! 

Must each person remove an egg from the basket?

 

Manholes

 Why is it better to have round manhole covers than square ones?

     I believe the manhole question is at the level of evaluation.  To determine a feasible explanation for round covers the student may have to appraise/assess why they would be round as opposed to square.  On the other hand, this question may be at the synthesis level.  Students would have to combine information they know regarding  squares and circles to develop reasoning why round would be better than square.  They would have to discuss their reasoning and logic behind round manhole covers instead of square ones.

  1. Your guiding questions were really helpful to me. I found that part of the exercise the most difficult. I really found your worksheet helpful for the manhole problem; which I didn’t get until I read the answer. But, with your synthesis question, the solution to the problem might be more visible for a student (I know it would have helped me).
