For Primary levels mathematics teachers

I'm delighted to find this site, which in many ways have similar views as I on problems and misunderstanding when learning mathematics.

suitable words

Purpose of communication is for the listener to understand the speaker. Thus, the language and words used should be selected with reference to the listener. However, I notice there are people whose purpose of communication is to express themselves. In this case, the media/language/words used were suitable to the speaker, and usually listeners do not understand.

When I am a listener in such situation, I won't be too anxious to know what's the message, because that's not the purpose of the speaker to speak in the first place.
