To learn from the best about 3 Act tasks see Dan Meyer’s blog
My students and I LOVE Estimation180 but I have to carefully select which estimations we do since some are over their heads (I teach 2nd grade). Since we are a BYOT school, my students and I have decided to create our own estimation tasks and take pictures, videos, etc. One student wanted to estimate how many counting bears were in a bag so they got in groups, grabbed bags, and started estimating. They, of course, had to do a high and low estimate first and then counted their bears to see if they were close. They took pictures and videoed themselves counting the answers. It was great.
This gave me the idea of creating a 3 Act task with a larger number of bears to encourage my students to add four 2 digit numbers (our upcoming skill).

What do you notice? What do you wonder?
- How many counting bears are there? Estimate.
- Write an estimate you know is too high. Write an estimate you know is too low.
