Day 4

Day 4 - 25th August 2011

Expose variation in word problems

3 situations in an addition/ subtraction problem:

1. Change problems (unknown can be the final, change or initial)
2. Part-part whole problems (e.g. there are 37 students in a class. 19 students are present. how many students are absent?)
3. Comparison problems (comparing at least 2 quantities. e.g. i have $37, you have $2 more. how much do you have?)

Children do not learn well through repetition. Exposing children to a variation of word problems encourage children to use the same concepts to work with different problems. This will help teachers to find out how well the children understand.

Fractions

The condition for naming is to first form equal parts.

The idea of 1 fourth:

We were all given a piece of square paper to fold it into four equal parts.

It was clearly demonstrated to us that no matter how we fold the square paper, as long as we get four equal parts, we can name it!

However, being equal does mean it have to be identical! - idea of variation.

And lastly, from this activity we experienced the process of CPA!
