[quote=Anonymous]Get your kid on www.dreambox.com and they'll quickly start to see that it's useful to be able to break down and build up numbers using what you know about sets of two, three, five, ten, and so on.

For example, let's say you have 5+5.  Well, you know what your hands look like, you know you have ten fingers, so rather than count out 1, 2, 3, 4.. 10, you can "know" it because you've counted and seen it a zillion times.

Next you have this problem: 5+4.  Well, to start, a young child is going to count.  Soon they'll grow tired of that and after seeing how easy 5+5 is, they can say, oh, 5+4 is one less! That's 9.

And then 6+5 is also easy, because it's one more.

Then move up to dealing with 10s and 20s.  10+5 is obviously 15, so 9+5 must be.. right, one less.

You can try to "put" these math facts in your child's head, but that will be frustrating.  It's good for kids to see the patterns, test them out, quasi-"discover" them in supported instructional activities.
