Talk:Geometry for Elementary School/Points

I would not call those non-points 'balls', but rather 'discs'. Especially since 'ball' means sphere in the next chapter ('Lines').

Plane shapes
I am going to change back "plane shapes" to something like balls, discs or circles. I think it is bad enough to have an informal discussion of limits for elementary school students, we shouldn't push toward generality at this point. If the "limit" of one particular shape suffices we should stick to it.

Also, It is also not clear to me that any plane figure would do, at least with the definition I think of as the limit of a sequence of sets in the plane. But this point is kind of irrelevant, since it probably wouldn't come up again in ones education until measure theory. Thenub314 (talk) 08:28, 24 April 2010 (UTC)

Is this a high schools mathematics? Omwengareuben (discuss • contribs) 04:56, 26 November 2017 (UTC) Of course this is tautological since the definition of a 'line' is 'two connected points', and the definition of a 'plane' is 'the surface specified by three points'. (and the three point are not on the same line )

A typo detected
In the paragraph:

"When we name a point, we always use an uppercase letter. Often we will use P for "point" if we can, and if have more than one dot, we will work our way through the alphabet and use Q, R, and so on. However, nowadays many people with start with any letter they like, although the P still remains the best way."

the underlined bold word should be removed.

And good work!!
