Interesting lesson as Number Bond is discussed. I noticed throughout all the lessons, there is always a need for number bonding (relation of numbers). This is also known as number sense.
When a child have a strong foundation in their number bonding, the child is able to understand different concept quickly. For example, instead of subtracting 7 from 10, the child will be able to see that 7 and 3 makes 10.
Next, putting a 10-space table chart in class is useful as it gives the children the visual cue to the combination / arrangement and / ways of making 10.
I believe, when a child is introduced to numbers, we can start to introduce bonding. For example, when they said 1 apple, 2 apples, 3 apples, we can use the concrete object to form different ways of making three. We can intoduce 2 and 1 apples makes 3 apples, and so on...
