I'm hoping to use this for my son, so I've been going through the math exercises, and I found what I consider to be an error. OR, at any rate, you marked an error that is not. Rounding 12.50 to the nearest integer should technically yield 13, I believe. If rounding a number from a final 5, if the number is odd, you round up, but if it's even you leave it as is. e.g. 12.50 rounds to 12 whereas 13.50 rounds to 14.
