**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?!
