Math (and biology) facts for 5 year olds

Last night The Pea was grilling 3Po on the math facts she considered essential to any entering kindergartener. 3Po answered 1+1, 2+2, 3+3, 4+4 and 5+5 with ease......

Pea: What's 6 plus 6?

3Po (thinking hard)....... twelve!

Pea: What's 7 plus 7?

3Po (thinking hard): Um........

Pea: Use your fingers to count, 3Po!

3Po (looking annoyed): Well, I don't have fourteen fingers!
