I don't know how well this puzzle will translate to a toot. Imagine each line is on a card: □□▷ □□□ ■■ ■ □■ □▷▣ ▣ □▣ ■▷ ■▣ ▣▷ □□■ □▷ ▣▣ □□ □ ▣□ □□▣ ■□ ▷ □▷□ □▷■ ▣■ □▷▷ Put them in order. (The 5th graders could do it, but they did have a helpful example first... There may be more than one solution, but I think there is ONE really good order. Can you find it?) (I should also mention that every adult I've shown this to gives up. But I only showed it to two rather grouchy teachers.)
The nice thing that happened in class today: Grade 5 students solve a puzzle where they put cuneiform numbers in order (there is no guidance, just work with the symbols, how do you order them?) I told them they are like archeologists cracking a code. They did it! "But were is zero?" "It wasn't invented yet." I said this seriously. I mean ... it's true. Later that day the same student asked if it was a joke. I got to tell them no! Zero had to be invented. Everything had to be invented!
Bases. (decimal, binary etc) are best explained through examples. "You can only writer three symbols in base 3. These are: 0, 1, 2" So you count: 0, 1, 2, 10, 11, 12 ... I think the word "symbols" is confusing, but so is "characters"? Students don't think of numbers or letters as "symbols" or characters. The card sorting puzzle helps with this. But I'm always refining the language: How would you put this as plainly as possible?
#desmos is out of control. Here is my guide to all of the features I've found so far. You can make logic gates in there. You can do lists and iterate things: They've added summation and it's a little strange sometimes how it works. This threw me. You set i to be a list and it give you three answers. It won't evaluate it if you don't set an upper bound. I'm excited but also a little horrified that this is the new SAT calculator. It's just so feature-rich. image

Remote software updates, feature enabling/disabling, and the most extreme remote bricking raise several "consumer rights" issues that have not been adequately addressed. #tesla #solar #rightToRepair
