Math Curse ~ A fun picture book full of math problems!

I am not a huge fan of math...but this picture book "Math Curse" by Jon Scieszka and Lane Smith was so much fun to read aloud. The kids and I tried to work out most problems as we were going through it.
A couple of quotes from the book that made us laugh:
"English is a word problem: .... #2 Does tunafish + tunafish = fournafish?" I know, I know...pretty cheesy but we loved it!
The other one was :
"Social Studies is a geography problem: The Mississippi River is about 4000 km long. An M&M is about 1 cm long. .... #2 Estimate how many M&Ms you would eat if you had to measure the Mississippi River with M&Ms."

Dragon and Fairy enjoyed this quick picture book. For another Math related book suggestion, that is a little bit longer, we liked reading "The Cat in Numberland" this past spring.
