Exercises from activity book Thinking skills: 1. Identifying 2. Logical Mathematics Moral Value: 1. Carefulness 2. Diligent |

Refleksi :

For step 2, subtraction with regrouping, pupil Toh Yue Qing still not really understand the concept. She only understand when I said “ If you have 2 sweets, would you be able to give me a sweet?” when I asked her this kind of questions by giving her a more concrete consept instead of numbers, she could easily solve the problem. So I think that’s the way she could really understand a concept.
