SESSION THREE: 25TH SEPTEMBER 2013, WEDNESDAY

Third day of Elementary Mathematics with Dr. Yeap, MORE problems and QUIZ!!!

3 THINGS THAT WE LEARN IN MATHEMATICS:
  • Conceptual – cardinality
  • Procedural – procedures in doing math sums
  • Conventional – things that need to be exposed to, for example, rote counting


PROBLEM OF THE DAY:

Problem 9: Addition of 2 digits numbers to form 2 digits number answer.

We created our digit cards from 0 to 9. We have to use the number cards that we have to form addition sums. It was fun and required much thinking. After manipulating with our digit cards, here are some observations that we have found:



The digit “0” can only be used in the sum.

The digit “9” can only be used in the ones place.

The largest number that we can have the answer of is 98.

The smallest number that we can have the answer is 39.




Problem 11: What are the different ways to share a piece of rectangular chocolate equally among 4 persons?

Similar shapes:
Rectangles


















Triangles

Different shapes

















I was really amazed that there are actually so many ways that we can share a rectangular chocolate among 4 persons.

That’s all for today~~
