BCAMT 2022 - The Mathematical Power of Building to Specifications: Nat Banting



 - The teaching move keeps the thinking going

- A "move" can be allowed, if it keeps the thinking going

- Do the move you anticipate will keep the mathematical thinking going

- You can change the constraint, etc, it's your math!

- It feels different to "go in the opposite direction" (you own it, you discover it, you belong to it)

- The solution to the task is the argument. The benefit to this is the middle space. 

Menu Math:
1, 1, 1, 1, 2, 2, 2, 3, 3, 3, 4, 5, 5, 6, 6, 9, 10 --> Build 10 fractions that, when added together, create the largest number. 


Switch: Build a number that has a remainder of _ when divided by _.

- Have students act as a designer. We, as teachers, are invited into what they know. 

- "Ask for forgiveness, not permission." - Student Agency

        When agency comes in, you've got to be prepared to be surprised!

- Keep students thinking. 

- You are allowed to change just a single group's instructions! Keep students thinking. 

- They are building sense. They aren't just pushing around the sense that everyone else has laid out. 

- It is always a good idea to let the kids be brilliant. That is never a bad idea!

- "A culture: If students are going to be designers, you need to build the agency of a designer." 

- Custom Functions: Build the equation of a function that...

        - Write a bunch of requirements on a bunch of cards; every day, flip over, 3 or 4 or...

- Here's our direction of schooling...what happens if we flip it? 

Why start with less than student potential? 

- We don't have a lot of time...why not spend all of it in student thinking?

- Bravery starts with access --> When students know that one or two classmates will answer that question, they don't have to be brave. When we allow that to happen, we stop the thinking. Requiring answers from all provides access to thinking and space that requires bravery. 

- "A gateway: Start by asking students to 'choose' or 'change' one thing." Thinking can be continued by this simple task.

  1. "A gateway: Start by asking students to 'choose' or 'change' one thing." Thinking can be continued by this simple task. I would love to try this. So simple. I just gave the matchstick problem to my 6s, an extension the next day could be for them to choose or change one thing about the problem.

    Love building questions. This is a great example of menu math. 1, 1, 1, 1, 2, 2, 2, 3, 3, 3, 4, 5, 5, 6, 6, 9, 10 --> Build 10 fractions that, when added together, create the largest number. I do a lot of building questions with place value and number lines.

    Will definitely follow Nat Banting.

  2. Also, I feel the above mean, median, mode question has merit. It relies on a strong understanding of each vocabulary concept and invites trying, and tinkering.

BCAMT 2023 - What is Extending? - Phil Stringer

 New Reporting Order has been followed up with videos Chris Hunter bit.ly/BCAMT2023 What does "extending" look like in your math classroom? Working in how to calculate using spreadsheets ("if", etc.) Extension is not synonymous with perfection! How do students set up, attempt, demonstrate, etc? We make answer keys with mistakes ALL THE TIME, and we are extending at Grade 9 math! Play with AI or ChatGPT to get extending and synthesizing questions.  WrongMath on Twitter -- collection of photos with bad math @xphils     pstringer@croftonhouse.ca

BCAMT - Peter Liljedahl - BTC: Closing the Lesson

 BTC: Closing the Lesson Consolidating a Lesson Have a conversation Teacher scribe "I've put up three questions from today's lesson, but I may have put them up in the wrong order. What should the order be and why? Turn and talk." Once they've decided and shared, do the questions together. You are scribing , not instructing.  This is the first opportunity for students to notice and name the variation. They get the questions one at a time, so don't really have time to compare and contrast during  the lesson.  [Guided] Gallery walk -- only relevant for a divergent task (every group does it differently and now we can look at all of those different options for solving) Do/Give Some Notes Not everyone wants students to have notes to look back on -- linear progression from K to 12 Notes help PARENTS see what's going on in the classroom.  Because of this, we've become way too obsessed with note HAVING, leading to becoming too obsessed with note TAKING Writing ...

BCAMT 2023 - Helping Students Enjoy Pre-Calculus 11, 12 and Calculus Courses - Ron Coleborn

What does it look like when students are enjoying a course?  The thinking process, as long as we feel confident and have support Getting the thinking and not feeling like we have to know it right away because of a test tomorrow, etc. Assignments, Desmos (activities and regular graphing calculator) Not easy because there is a lot to cover! Presentation Folder Most of the assignments in the folder should take ~4 days, so give a week or so. 1-1.5 class periods, the rest is outside of class.  Contact Ron: ron.coleborn29@gmail.com Seeking to find material that fits into both content and competency - what hits the learning standards as a whole?  Desmos:  Inserting picture and create graphs/points around that Mystery Functions - creating using piecewise functions Desmos Selfie - picture behind and create a graph pic (PreCalc 12 for transformations, could do PreCalc 11 with more simplistic functions) Example 2 Leap Frogs - Quadratics Either with counters and squares or the ...
