Saturday, February 28, 2015. 23 still isn't prime (sometimes). Who: J1 and J2. Where: walking around the neighborhood. When: after lunch on a saturday. In response to our earlier discussion that 23 is prime in the integers but not in the rationals, someone on Google Plus (either Curious Cheetah. Mentioned that 23 isn't prime in base 9. That led to another good discussion with the kids. Labels: 5 year old. Wednesday, February 25, 2015. Where: our reception room. When: after swimming lessons. 1) How to dea...

Sunday, December 28, 2014. Where: at the dining table and in front of our house. When: after lunch (observations from 19 December/day 18). Has made some progress. The root has sprouted. Maybe it is actually upside down and the avocado is confused? The pit split in the middle. There is a sprout in the middle. Some of the pit has peeled off. The exposed pit is a bit more rough than when we examined it last week. it feels like bumpy wax. Maybe it is actually upside down and the avocado is confused? The avoc...

Three J's Learning: May 2015
http://3jlearneng.blogspot.com/2015_05_01_archive.html
Sunday, May 31, 2015. Twist on an old puzzle and our number scavenger hunt. Who: J1, J2, J3. When: after lunch, before violin lessons. What did we use: mini-white board and things around our neighborhood. The first twist was to find how many answers there are to this puzzle. You can see us mid-work, having already identified two choices for the circle and several options for the other two shapes. Our number scavenger hunt. Last September, but I didn't really appreciate how good it would be for us until w...

Three J's Learning: a physical feeling for densities
http://3jlearneng.blogspot.com/2015/07/a-physical-feeling-for-densities.html
Monday, July 27, 2015. A physical feeling for densities. Thanks to Mom, our stair number line recently got a (partial) refresh with some snazzy new number posters. This stimulated a new exploration by J1 to study how dense different groups of numbers are. Well, that wasn't how he phrased it . . . J1's dialogue as he played on the stairs:. Hmm, what if I walk up the multiples of 2? Walks up skipping stairs, no problem here. Oh, that's pretty easy, but J3 might find it tricky. 1, 4, what's next ? 16, oh no!

Three J's Learning: January 2015
http://3jlearneng.blogspot.com/2015_01_01_archive.html
Thursday, January 29, 2015. Advancing the calendar trick. I've written twice ( first. About classroom experiences with a simple calendar trick that I originally got from Calendar Puzzles. Via Denise Gaskin's monthly newsletter. As happens so many times with these things, ideas from the kids make these activities into deeper and more interesting than I could have imagined on my own. Homework from them this time! For the reversed game, though, it isn't quite so easy. The relationship between the number...

Three J's Learning: June 2015
http://3jlearneng.blogspot.com/2015_06_01_archive.html
Monday, June 29, 2015. Programming class (grade 5 and 6). We started out with everyone showing their homework programs (drawing our names in Thai and English) and telling us one thing they really liked about the program and one thing that they found challenging. Here are a couple of highlights from the discussion. Reusing code: when do you write something new or just use code you have already written? We compared these two programs พิชชี่. Simultaneity: Jung was the only one (including last year) to have...

Three J's Learning: Equal? Ambiguous test questions
http://3jlearneng.blogspot.com/2015/08/equal-ambiguous-test-questions.html
Sunday, August 9, 2015. We have been looking at questions from a local exam contest. I thought two were worth discussing. Kaew had been in the mountains climbing for the last four days and recorded her distances on this graph (the first one below). The other graph shows the climbing distances from Ploy. Below the graphs are 4 statements by other people and we're asked how many of the statements are true. The statements are:. Weera claims: "Each day, Kaew climbed more than Ploy.". The math class answer.
