There are so many amazing things about the Estimate 180 site. There is a huge variety on the site. So many math concepts are covered in the over 200 estimation activities on the site. In a few weeks, I am going to use a series of lessons designed around estimating height and I am looking at another that estimates the amount of money in coins. You can browse the site or search estimations based on math topic. I also love that these are multi-day activities that are built to help kids think across time and to use understandings from one day to solve the next day's challenge.
Mr. Stadel must think about estimation all day every day because so many of these estimations come from real, daily life and I think kids will start seeing estimation opportunities everywhere after a few weeks of these.
I loved this site so much that I just had to share. I am excited to jump into another estimation with my kids next week (Cheeseball Estimations) and see where the conversations go!
