I rolled a large dice, students then built that number, compared their thinking to their partners by providing evidence of their thinking by counting their objects. This activity was a fun way to talk about what to do when your partner makes a mistake, how to kindly ask them to check their work and how to learn from mistakes. The most common mistake we ran into today in this activity was students miscounted 1:1 their objects. What did we learn from that? Putting objets in an organized manner (straight line, dice pattern, tens frame, etc) may help students to be accurate and double checking your work by recounting is something mathematicians always do.
