Thinking about Number Talks

School is out, summer school is over, what now? I now have time to explore, create and crowd source new ideas for next years students! I have already been busy this summer reading and watching videos and have so many ideas churning. Today I am just going to use this space to put some of those ideas on paper so I can use it for inspiration all year long.

I have said and heard other teachers in my department say that kids just can't do math without a calculator. We have talked about how we should incorporate more mental math into our classes. Sometimes we do, sometimes we start out strong, then give in. Why are students mental calculations so weak? Is it because they are taught to memorize? Are they taught strategies but once they are given a calculator they don't keep up the practice so their skills become weak or even non-existent? Besides mental math skills, what students really seem to lack is number sense. They seem to be so reliant on the calculator they don't even know if what they have typed in makes any sense. How am I supposed to combat this?
I have been looking into incorporating Number Talks into my Geometry curriculum. From what I have read, the number talks should help my students gain flexibility with numbers allowing them to manipulate problems in their heads to find the correct answers as well as teach them to communicate their ideas and processes. If I had a nickel for every time a student said to me "well I know the answer is right, I just don't know how to explain it," I'd be rich! The number talks should also teach them to listen to others' ideas and determine their validity. All in all it sounds amazing. I think this will really help to support my classroom philosophy. As the teacher, I am not the answer key. I am not the keeper of knowledge. Everyone can teach us, parents, friends, and classmates included. I really try to foster a feeling of community and collaboration in my classroom, so I think number talks can only help and they are only supposed to take 10 minutes of class time and I think that time will be well worth it. I watched a blog and someone presented the challenge to do 30 number talks during the year with 10 of them being within the first 10 days of school. I think I am going to accept the challenge. I couldn't find a lot of high school videos on YouTube showing the process. I am a visual learner so I was really hoping for a bit more insight. When I do try it, I may record and post them. Good or bad, maybe someone can learn from my victory or defeat.

Facilitating PD

I love all the typical things about teaching high school math. I love seeing those light bulb moments. I love having kids leave class with a bit of spring in their step because math class was "fun". I really love when I have set up an activity so well that I don't actually have to do any teaching and the math-magic just sort of happens in class. But recently, I have been thinking about finding a different role. Trying to grow and flex my teacher muscles in a different capacity. Over the last few summers, I have been really diving into some personal PD, reading books and blogs, watching videos and going to a conferences. Every time I  finished a book I felt was particularly inspiring or left the last day of a conference I kept coming back to "man, I need to share this with EVERYONE!" So lately, I have been kicking around the idea of instructional coach or math coordinator as a potential move. The idea of leaving teaching, which I think I am getting better at eac...

My Math Autobiography

After reading Kent Haines blog "The Process Column" on how he incorporates math autobiographies into the first few days of his class, I have been inspired to try it in my class too. Class officially starts next week and I am going to read them mine and ask them to write their own version as well. I have invited a couple English teachers to write their math autobiographies too (like Kent did) so I can share experiences as well. I am looking forward to seeing what my kids say.  Here is my math autobiography: I remember very little about my math classes from school. There are a few things that stick out, but not for good reasons. I remember doing flash cards in first grade and feeling the victory of completing a set and getting to move on to the next and the utter defeat when I missed too many and I had to keep that set for a few more days until I got better. I remember playing around the world in fifth grade, standing behind my classmate trying to be the first one to ans...

High School Kids Still Like Play-doh

Wow, what an amazing first week! After a summer of reading some great books, a week long math conference, and incredible conversations with colleagues I jumped in feet first and tried some completely new things this year. I was nervous every day this week, so nervous my stomach was doing back flips every morning and for about 2 minutes before every class period. I didn't know if my new ideas were going to be successful or flop. That uncertainty was very scary and hard to push through. But I made it to the other side relatively unscathed. Day 1- The Play-doh experiment So I bought some mini cans of Play-doh and as I greeted my students for the first time I had them pick a color, find a seat, then read the directions on the board.  Directions: Use the Play-doh to create something that you like, something that you don't like, and/or something that tells us about you. Please keep it school appropriate :-) As I walked around the room introducing myself to each person ...
