[quote=Anonymous][quote=Anonymous]I don't get it. If you don't count something (dots, apples, whatever), how would you know that 3 + 2 = 5 (when you are first learning it)? Do you just memorize the way you memorize multiplication tables? [/quote] Kind of. You memorize certain facts like 2+2, 3+3, 4+4 ..... and then you use those to help you with the other facts. If 2+2 = 4, then 2+3 will have to be one more than 4, because 3 is one more than two. 2+2 is called a "double" fact and 2+3 is called a "double plus 1" fact. You are supposed to be able to add +1 and +2 in your head, automatically. That's just "counting on"[/quote]
