Caroline Mukisa is on a mission to help parents to support their childrens Math learning and is a big fan of sneaking math into children's (and parent's) diets. She blogs as the Maths Insider.

This blog post is the culmination of a fight; a really big fight. You see when Sol invited me to guest post on Wild About Math! I took it as an opportunity to seize possession of the big, shiny, blue book my 10 year old had kept hidden away for the past 6 months so that she wouldn't have to share it with her brother, The Guinness Book of World Records.

Following the liberation of the big, shiny, blue book, her brother wasn't going to just let me take it and read it for research purposes, he wanted it and he wasn't giving up without a fight. He even brought in reinforcements, his 2 little brothers. Guinness World Records 2010, you see, still has thousands of extreme facts but also has thousands of photos of the biggest, fastest, smallest, loudest and more, so even my pre-numerate 18 month old wanted to take a look.

I did win the battle (OK I took it back while they were sleeping) and present below 10 math questions using fascinating facts from Guinness World Records 2010. Answers at my blog.

#### Just warming up
