Math Rocks Mission #9: Try and Reflect

As you may or may not recall from our session last week, I had mentioned there are two homework assignments before our next session. The first is Mission #8. And here is the second:

  • Choose a number sense routine like Quick Images or Choral Counting, or choose some other short activity like Estimation180 or Which One Doesn’t Belong? The key is the activity should only take about 10-15 minutes of your time in class. I also want it to be an activity you want to do with your students. I don’t want you to feel like this is some artificial task you’re doing to check off a box, “Yep, I did my Math Rocks homework.”
  • Try out the activity in class. Pay special attention to what the kids are doing and saying.
  • Take photos of any work that is shared. For example, if you do a number talk, take a photo of the board when you’re done. Avoid having students’ faces showing in any pictures or any identifying information.
  • Write a blog post reflecting on the experience. Some questions to consider: (Some! Not all! You don’t have to write a book.)
    • What activity did you pick and why?
    • What kind of planning did you do beforehand?
    • Was this the first time doing the activity with your class? How did you introduce it?
    • If you’ve done the activity before, what are you noticing about your students as they continue to encounter it?
    • How did the activity go? What kinds of things did the students say and do during the activity?
    • What are you curious about?
    • What surprised you?
    • What frustrated you?
    • What are you proud of?
    • What would you do differently next time?
    • Do you want to use this activity again with your students? Why or why not?
  • Include at least one photo in your post so readers can get a glimpse into the classroom experience you’re describing.
  • Tweet out a link to your reflection. Include the #ElemMathChat and #MTBoS hashtags.

Happy teaching!

    • Here is my Mission 9 Blog:

      I cannot convince anyone to let me try Estimation 180—I’m not giving up yet. I have received several requests for number talks, and that is what my blog is about. I had a really successful, unique experience with the number talk by replacing the “=” sign with “is the same as”.


  1. I have been invited to model number talks in several grades here at my school! Pre-K (I was sooooo nervous), 1st, 2nd, 4th. The fun part about them is that I think that the teachers learned as much about their students as the students learned about the talk.

    A surprising aspect is came from 2nd grade. I took a string from the book, Number Talks, that begins with 19 +1. It sounds simple, but the conversations have been rich! One thing I have been doing is trying not to use the = sign, and I use the words “is the same as ___.” In a couple of 2nd grade rooms, just 19 + 1 has been the topic of conversation for 2 days. (15-20 minutes each day!)

    Chapter 2 from Making Number Talks matter was really enlightening, even though I have been doing number talks for 10 years, called by a different name.

    This has been an awesome journey so far!
