When I look at hundreds of hours of videos of Japanese classrooms where they get high performance from ordinary teachers and hundreds of hours of US classrooms where we get ordinary performance from very good teachers. I see the goal of the Japanese teacher is different from the goal of the US teacher. The American teacher looks at a problem they are going to use in a lesson and asks themselves, "how can I teach my kids to get the answer to this problem?" The Japanese teacher asks "what's the mathematics the students are supposed to learn from working on this problem?" - Phil DaroAnswer getting, that seems to be the issue. Watch the video and then take a look at Keith Devlin's post on it.

We really like this activity which is basically a tweak of a very common activity done by most teachers when having students learn about scatterplots. In this case we normally have students measure their various body parts and then compare them to see if there is a relationship. The twist here is that we include comparisons that kids can make to real people about their heights, arm spans, foot size and hand size. See all of our templates here

Annie from the Math Forum talking about apps to help support conceptual learning. Apps include a sketchpad sketch that deals with types of triangles, an app that introduces the idea of distance time graphs, an app that introduces the idea of systems of equations and algebra tiles.

I love this activity by Nat Banting. There are all sorts of ways you can demonstrate the concept of conditional probability. But playing egg roulette might be the best of them all.
