Back when I was creating the tasks for Estimation 180, my goal was for my students to develop their number sense one day at a time. Therefore, as random as some of the tasks might appear on the site, I tried my best to create series of tasks so students could use referents from previous days to tackle the current estimation task. Here are my top 3 favorite series. They are fun and have made teaching and learning math enjoyable and meaningful for both my students and me. I hope they bring you joy too!

Days 1-5: The height of my family and me (I made a video on How I Use Days 1-5)

Days 205-210: Cheeseballs (BONUS: watch the videos of me attempting these tasks)

Days 176-180: Basketball court (walking, biking, scootering... distance, rate, time)

Be sure to look for the downloadable handouts that go with each of these series of task.

If you like these, then I think you're going to love the Estimation 180 Toolkits. They're like a supercharged Estimation 180 experience. Check out the FREE Preview of the toolkits.
