I'm so excited to see your work! I'm at NCTM (the National Math Conference) and this is the kind of problem we should be seeing more often in second grade classrooms. I'm hoping to skype with you next week to talk more about this challenging problem!!
We had a lot of fun solving it, Ricky! Can't wait to hear from you!!!May need to switch days - as I will now be administering the STAAR on Wednesday. What other day are you available to SKYPE?
