I remember she used to count from 1 to 51 for 1+50.
Agh, my kid is doing that! I've tried to explain about "counting up" from the larger number, and she just looks at me like I'm from Mars. She's got this huge verbal working memory, combined with much less impressive visual-spatial skills. She looks like she's leaping ahead in math, but she's not learning the short-cuts she's going to need. (I asked her how many wheels three cars have, and before I could even start sketching groups of four wheels she popped out with "twelve!" She did it entirely by counting in her head.) Glad to hear your kid got over it, I hope mine will too!
