The 5th Grade Math Club discovered a mistake in a task created by the Mindset Mathematics team, and their teacher, Ms. Maurer, wrote the team to see if her students were correct...please see correspondence below:
"Hello,
I note that you were part of the team that developed Mindset Mathematics. The resource has been a game-changer, providing a framework for emotionally healthy access to math for every child. The kids LOVE the tasks (yay!).
Is it possible that the mathematics puzzle (rectangular solids views are on page 31) requires 16 yellows to complete? My 5th grade math club kids have convinced me that another yellow is necessary to complete all of the 6 views...
Thanks,
Sue from Ukiah, California"
"Hi Sue,
Your students are right and congratulate them from us on their justification and argumentation. Despite our best efforts WE made a mistake and your students caught it. I'm attaching the corrected images here, but the truth is they probably had more fun finding our mistake than they will building the corrected version.
Thanks for reaching out!
Jen"

"I am very proud of the 5th grade students! It was really fun to see how empowered the students have become to argue for and justify their thinking." -Ms. Maurer
