In May, our school took the 8th graders to Washington D.C. and New York. I was able to capture a few estimation tasks for class and the site. There were many opportunities to have estimation conversations with students about memorials, monuments, sceneries, and other happenings during the trip.
Day 156: We were at the Abraham Lincoln Memorial and there's a giant penny that greets you at the entrance of a small museum hallway. I've seen this penny on previous trips, so I remembered to bring my measuring tape.
Day 157: We stopped off at The Smithsonian Air & Space Museum (Steven F. Udvar-Hazy Center) right after our plane landed at Dulles Airport. They had a Dowty R391 Propeller. The camera angle doesn't do this propeller justice.
*Side note: your armspan (from middle finger to middle finger) is supposed to be approximately equal to your height. This was a fun conversation and activity to have in class. Try it!
Day 158 and Day 159: We took a boat ride on the Hudson River around The Statue of Liberty. As everyone was exiting, I noticed the emergency signs stating benches had life jackets stored inside. Even though the benches could probably fit more than posted, talk about the logistics/problems behind storing too large of a number of life jackets in a bench.
Day 160: We were at Times Square and LEGO had a Star Wars Spacecraft on display. The answer has even more fun facts: weight, time to design and build, etc.
I believe estimation is key to building number sense and being a better problem solver. I explore middle school math with my students.
