I recently saw this video from Haichi Toaru (@haichi_toaru) referenced online as an example of 3rd grade math in Japan. At first glance, the whiteboard looks a little intimidating, with so much kanji and geometry packed on screen at once, but I think Toaru-sensei is pretty great and this is not only appropriate for a 3rd grader, but a fun lesson for an adult learner of Japanese to pick up on some new geometry-related vocabulary.
