Math Links for Week Ending Dec. 29th, 2017

I love this activity from @Desmos for introducing probability concepts. Especially the 36 spinner slides.  So much goes into coding those pages so having someone do that for you is a gift. Have your kids try it out.

I like this activity from @MathEqualsLove about continuous vs discrete data. Students are given six cards with three one of three representations on it (situation, graph and variables). The other two are blank. Great for discussion on the ideas of continuous vs discrete data.

I really like the nature of randomness and as it turns out getting things to be truly random is pretty hard. This tech company that protects 10% of the websites on the net does so by requiring a regular stream of random numbers. And how do they do it? Lava lamps. Thanks to @Esping_Math for this one.
