### Day 2 - Whole Numbers

If you ask Google what is whole number?

Whole number is...

A whole number is a number that is not a fraction of a number, a percentage or has a decimal. If you have a number like 21.32, it has a whole number portion (21), but in itself, this number is not a whole number because it contains a fraction (.32). The term integer or natural number may be used to define a whole number.

Today we learnt about whole numbers and using the ten frame, we did and find different ways to find the total of 5, 6 and 7. It is very useful as it led us to see other kinds of patterns, like arranging to make tens, counting in 5, or arranging it to see it in 6 each which makes all in the total of 18. And that is one of the way which the children learn, through visualization. The use of the concrete materials are also important in visualization and another way which we learnt how children learn is CPA (Concrete, Pictorial, Abstract).

We also learnt about the 4 uses of numbers; Ordinal, Nominal, Measurement and Cardinal. And in ordinal numbers, there are different concepts in time and space where we should use it appropriately, for example in a race where only the 1st is distinct, we can say that that person is 1st in the race, however, for the others whose ranking are still not determined, we can only say, that person seems to be 2nd from the finishing line. And that is the distinct and difference between time and space.

So far, I have learnt and understood:

How children learn:
1. Patterns
2. Visualization
3. Number sense
4. Metacognition

Ways to teach a child:
1. Exploring
2. Role-Modelling
3. Scaffolding
4. CPA (Concrete, Pictorial, Abstract)
