The Grand Random Challenge: The most random maths questions ever! (English Edition)

A collection of the grandest and most random maths questions for you to have a go at.
How many times have you encountered a learner who looks at a mathematical problem and says “I can’t do that – I don’t know anything about cakes” or similar? As a Functional Skills lecturer, it is something that I encounter almost on a daily basis. Learners can do the maths, but they just do not understand how to use it. Traditionally as teachers we have just kept on feeding learners with a varied diet of exactly the same thing – no wonder they become disengaged! As a profession we can do better than that and our students deserve that much at least.
These Grand Random Challenge cards stem from my agricultural background (no pun intended) and perhaps indicate more about my mental thought processes than my natural mathematical ability. However what they do provide is an opportunity to help learners develop self-confidence with using numbers and an ability to put thought into the process skills required in order to answer a random mathematical problem. Generally there are no exact answers to these questions; it simply depends upon assumptions and estimations made. For the pure mathematician this might be a step too far, however for the pseudo scientist or mathematician it is this process that lets many down. The intention is that by participating in the Grand Random Challenge learners will be able to travel from what they do know to somewhere they had never considered previously. A canal full of tomato ketchup for example!
Hope you enjoy
