once upon a time I would kill for a great lesson idea, then I started reading the internet and have too many

If the deluge of interesting problem-based material on the Internet overwhelms you, as it does Jonathan Claydon, Geoff Krall's curriculum maps are a great place to start. He's taken the Common Core's scope and sequence documents and combed the Internet for items that fit. He's included a few of my own items, some items from the Shell Centre, along with a lot of great lesson ideas I'd completely forgotten. Bookmark it. Throw him some love in the comments.
