Estimation 180 took a bit of a summer break. However, a couple of productive contributions include the guest posts from other educators and the Estimation 180 handout post.

As we warm up for the new school year, I'm adding a few estimates that came up during the past couple of summer months. Happy summer (what's left of it)! Enjoy:
Day 161: Remember all those coins? I took them to my bank's Coinstar to deposit them.
Day 162: Let's find the combined weight of the bowl and all those coins from Day 161.
Day 163: Another height estimate. I know. This one comes from my time at Drexel University working with The Math Forum and other educators during our EnCoMPASS work. 
Day 164: Nothing says summer better than water play, right? How many people can squeeze into this pool?
Day 165: How many people can squeeze into this large pool?

Speaking of summer and pools, check this out. I came across this at my sister's pool. I'm extremely curious about this. How cool?!

I invited a handful of people to write some guest blog posts for Estimation 180.
