*Thanks Fawn for passing the links on to me.
I'll let Joe do the talking in his posts, but here's where Joe made my heart skip an estimation beat:
Joe incorporates a number line into his estimation challenges in this post. My favorite quote from Joe:
"It's clearly a work in progress, and we need to continually reflect on what we are doing and where we are going."
Joe does some fine work with a Clementine. Brilliant! I have estimation envy. Pay attention to the extension activities the kids came up with in this second post:
"We wondered whether all clementines had nine wedges, and agreed that this would be an interesting question to explore. Would bigger clementines have more wedges? This was another question that arose in the discussion."
Be sure to leave Joe a compliment (comment) as he's rockin' the number line! I'm adding this to my Estimation 180 tool belt!
