Is Addition like Subtraction? Math Monday and Wonderopolis


We are going to be the "Wonder of the Day" on Wonderopolis Thursday May 28, 2015! 

One afternoon all the first graders were gathered on the carpet discussing what we wanted to learn about numbers. When, just like that, one inquisitive mathematician asked "Is addition like subtraction?" A few students shared their thoughts on this question, but as they did they found themselves wondering even more. Knowing we needed more time to think about this and to try out a few ideas, we headed out into the workshop to grapple with our inquiry. 

The more we explored the more we wondered, so we sent this tweet~




Then, @CherylGehres sent us this tweet~

It was a great cupcake frenzy!
Friends who saw the similarities tried to convince those who did not. Those who saw the differences set out to prove they were indeed different! The debated raged on. Then, just like that we got these tweets-







AND then THIS...



We are THRILLED to announce that on Thursday May 28, 2015 we will celebrate as OUR wonder will be the featured "Daily Wonder!"  Please visit our wonder on Thursday, May 28, 2015!

Our final finding was, "Yes, addition is like subtraction because if you take something away and then put it back it's the same again."

I really enjoyed seeing the thinking your students are doing digitally and how they are connecting with other students about math. Thanks for joining today.
