The class started with Dr Yeap reviewing the previous session; talking about whole numbers and going through the different theories. And I am reminded about giving children variation and not repetition!
Then, the problems arises.
We did Problem 9,10,11 and 12.
Problem 9 and 10 involves addition and here, I would like to share about Problem 9.
Dr Yeap got us to write the digits '0' to '9' on a piece of paper. The problem was to use the digits (digits are not to be repeated) to make a sum. For example, 32 + 54 = 86.
Note that not one digit was repeated.
I had tons of fun making different sums and I shared the addition that I had with Liyana. We challenged ourselves to create different sums and to count how many possible ways to make a certain number. We then realised that the greatest possible number that we can get is 98 and the smallest possible number is 39. It was such a fun experience for me and I really, really, really want to implement this activity with the K2 children when I had the chance. =)
