My son has just started year 6 (year 7 in the UK).
I want to help him with the topic they have started the year with, but I have no idea what it is called in English and I'm struggling to find anything on the usual sites I go to.
As a rough translation it seems to be called "groups" of the mathmatical kind.
He has to produce equations (?) like these below (if it doesn't format properly please read the brackets as the curly kind)
charactisation
A={a|a is a letter from the word "sink"}
list
A={s;i;n;k}
And then an Eulero-Venn diagram to show A, which I can't do here.
Theroy was by Georg Cantor
Started the above yesterday, today have added improper and proper sub groups, and the use of a sysmbol that looks like a squashed C,( so the arms are longer but it is more squat), and the same symbol crossed out to show a group is not a sub group of another group and the same squashed C with a dash underneath for the improper subgroup that is the orginal group, and a crossed through O to show the improper "empty" group.
He is having a hard time processing all the info, although we more less have the concepts sorted he is a bit fuzzy in places and I'd like to get him some less "dense" (and more example rich) explanations and practice....but it is a bit hard to do when when you don't know what you are looking for title wise (:
Hope I haven't mangled the explanation too much, quite hard to decribe in words.
Really grateful for an info about what the above is called.
