Kids were engaged, came up with a solution path, adjusted it as needed, persevered, and explained themselves. Maybe the only thing I could think of would be to try to communicate in writing as well? Great job.<br /><br />BTW, the best example I have seen that connects the area of four circles to a sphere's surface area is this: http://www.youtube.com/watch?v=VvFYZLpMbR4<br />Robert Kaplinskyhttps://www.blogger.com/profile/12730219834465583755noreply@blogger.comtag:blogger.com,1999:blog-2256375873271579383.post-11480325196470457732013-05-20T12:15:47.690-07:002013-05-20T12:15:47.690-07:00I hate when I read your blog, because you make me ...I hate when I read your blog, because you make me realize how boring I am (can anyone say Bueller?) My concern with this in a high school class is that students would just proportionally reason, but it would not match the objective, which of course is to find the surface area of a sphere. <br /><br />I echo Nathan's thought about the surface area. I've always wondered how I could explain to the students why the SA of a sphere is what it is without calculus. I am having a little troubles visualizing it. <br /><br />As for a sequel, what about a FOOTBALL?

I love the pre-lesson estimation on 101qs and on estimation180, talk about fun and safe entries into the problem. I'm definitely stealing this in its entirety. For sequel, I'd have a larger ball (tennis?) for kids to estimate. Then I'd have kids estimate with different coins, maybe with nickels and dimes. <br /><br />Thank you!!Fawn Nguyenhttps://www.blogger.com/profile/03605571262680195155noreply@blogger.com
