Important Notes on Model Drawing

Dear 2C,

Some of you are struggling with model drawing.  Do not give up and keep practising. Below are some pointers that I always remind you in class when drawing models.


1. When you read a word problem, determine if you need to draw 'part-whole' or comparison model.
 If there is a word 'than' --> use comparison model . Otherwise, draw part-whole model.

2. When drawing comparison model, make sure your bars are aligned so that the difference between the bars is read accurately.

3. Some important key words are 'more than' and 'fewer than'.  The person who has more will have longer bar and vice versa. So it is important to understand the story sum and determine who have more and who have less.

4.It is important for you to be able to rephrase the question. For example, 'Ali has 20 fewer marbles than John' is the same as 'John has 20 more marbles than Ali'. This will help you to draw correctly.


5. Finally, a model must have
1) Label ( numbers / names)
2) The arrows / roof/ bracket (To indicate the start and end point )
3) The question mark ( What are you finding?)

Get your model drawing right as this is the foundation to understanding concepts in Upper Primary.

Happy Learning!
