Christmas and Maths

Being the nerd that I am, there are just tons of things that we can relate numbers to in holidays. Christmas is coming up and there are a plethora of number related fun that we can have like the probability of obtaining a certain present, estimating the price of a present (taking into account the Christmas "sales" that were present at the time), or the usual estimation of the speed of Santa based on the weight of presents using statistics of popular "wished for" gifts of the year along with average reindeer speed, wind resistance, entry/exit house time, etc.

There is quite a list of things you can do this holiday season, but one that I stumbled upon was this one:

12. Unwrapping Gifts (and Math)

Well, I doubt that anyone will be in the mood, but here goes!

1. Determine the probability that Dad gets a tie.
2. Estimate and time how long it takes to unwrap all the presents.
3. Compare and contrast this with how long it took to wrap them.
4. Chart the number of gifts received versus those given.
5. Estimate and weigh the bags of recycled wrapping paper.
6. Explore nets with the extra boxes, and measure them using cubits.
7. Sort your gifts into Venn diagrams and make a pie chart to illustrate your findings.
8. Line up all the Christmas chocolates into arrays; sort, group and put them into sets.
9. Use the leftover ribbon to explore topology and create a gigantic mobius strip.
10. Try to build a rhombicosidodecahedron out of the recycled wrapping paper or just take a short break from math.
