The 8 + 6 story

For today's lecture,
we did a problem titled ' 8+6 story' where each group has to come up with  problem story which consist of the equation.
So here is my group's problem story:
John has 8 marbles.
Johnny has 6 marbles.
How many marbles they have altogether?

After each group have presented, Dr. Yeap mentioned that he could see different types of problem story.
1) part - whole problem story
Example:
Ben has 8 pens.
Tim has 6 pens.
How many pens they have altogether?
It has no concept of time of what they have now.

2) before - after problem story
Example:
Lila has 8 pencils.
Shanti gives her 6 more pencils.
How many pencils does Lila have now?
There is a change in lapse of time.

3) comparison problem
Example:
I have $8.
You have $6 more than me.
How much do you have?

Therefore I have learned that there are different types of problem story. It requires the student to be able to understand the problem and visualize in order to solve it.  And I found this table that illustrates the different types of word problems.

Dr Yeap also shared some significant information on what are the basic knowledge a K2 child should posses before going to P1.

1) Language - to read, to communicate with peers
2) Concrete Experiences - plenty of concrete experiences leads to visualization and imagination.
3)Number Sense 
4) Patterns
5) Social skills
