These are Math conversation starters that you could use in just about every class to get the ball rolling. They are presented in no order and all created by teachers for teachers and are free for you to use
- Between Two Numbers - visualpatterns.org, @fawnpnguyen, comes a new site. On this site you are given pairs of images and asked to compare them somehow. Proportional reasoning skills are the main idea here and eventually she expects to have enough so you could do one per week.
- Math Before Bed - @MrOrr_geek. On this site you will see images with question prompts that you could use to start a math fight or get kids thinking. I'm not sure how long he can keep it up but he has put up a new one every day since it's inception. They run the span from k-12 so there is something for everyone.
- Estimation 180 - @Mr_Stadel, this gives you and your students something different to estimate every school day (that's the 180 piece). Don't forget to check out the links on each that give previous estimates.
- Visual Patterns - @fawnpnguyen will literally give you hundreds of examples of visual patterns for students to extend. And of course there is a teacher's guide.
- Fraction Talks - @NatBanting, this gives you many images that are broken up in ways that you can then use to talk about fractions. They are done in a way that they have a low floor high ceiling (I think). Don't forget to see the Fraction Talks tweets as well and I even made a online websketch of a dynamic fraction talks image here.
- Which One Doesn't Belong - @MaryBourassa inspired by the book by @Trianglemancsd of the same name. The premiss is simple, there are four things and students have to decide which one doesn't belong. The beauty is that there is always a reason that could be given for each of them to not belong. The categories are shapes, numbers and graphs and there is even a section for incomplete sets.
- Math Talks - @fawnpnguyen there are several prompts for student discussion as well as sample student responses. There is also a teacher's section to help you figure out how to pull these off in your classes.
- 101 Questions -@ddmeyer has a huge number of images and videos (less than 1 min long) that try to illicit a mathematical response from students. Anyone can submit media and then are asked to ask a question about the images or videos they see. Those questions are then compiled so you can see them all. Some of the more popular ones are expanded into full 3 Act Tasks.
- Open Middle - @Anderson02B, @RobertKaplisnki, @Math_m_Addicts, @danluevanos and @zmill415 and based on an idea from @ddmeyer. It has prompts for students ranging from k-12 organized by topic. The premiss is that each of these prompts has a fixed beginning and end but the middle has many possible pathways.
- Graphing Stories - @ddmeyer and @Buzzmath that give many examples of situations for students to take some motion or action and turn it into a graph (eg position-time). There are simple instructions and a basic handout to get kids going.
- Number Talk Images - @Pierre_Tranche this site give several images that you can use to spark a conversation with students. They are organized into Dots, Photos and Strings and there are some great ones here.
- SolveMe Mobiles -
- Daily Desmos -
- Would You Rather - @jstevens009 plays that party game where you are given two choices and asked to choose. The difference here is the theme is math.
Next come some blogs. There are far too many to point out here but I thought I would point out a few where there are consistently things being created and shared out.
- Engaging Math - This is where my teaching partner and I house all of the activities we've developed for grade 7-12 math (Ontario Standards)
- Found Data - I'm a fan of stats but sometimes it's hard to find interesting data sets. So I started this blog to house data sets that I have found or created that I think are either interesting or helpful in teaching a particular statistical concept.
- Tap Into Teen Minds - here @mathletepearce has been creating 3 Act Tasks and other activities for years. Everything is tagged by both Ontario curriculum and Common Core standards.
- Mr Orr is A Geek - here @MrOrr_Geek does a great job of sharing out his activities both iPad centric and otherwise. He's done some work on spiralling, with 3 Act Tasks and has shared out some great stuff on standards based grading.
- Making Math Meaningful - if you like spiralling and are looking for resources for grade 10 applied or 10 academic then @MaryBourassa has a complete day by day of each course (among many other things for courses like MHF4U)
- Slam Dunk Math - here @AlexOverwijk typically takes activities and does a deep dive on them. They are heavy on detail and focus on creating a thinking classroom
- Wheeler's Thoughts on Teaching - here @Wheeler_Laura shares out full lessons, often using Pear Deck as her main tech tool. She also does a great job of #sketchnoting bigger teaching ideas, pedagogy and concepts.
- Dy/Dan - probably one of the best know math bloggers, @ddmeyer posts regularly and consistently puts out high quality stuff (check out his Vimeo channel) not to mention his 3 Act Tasks and the conversations and math fights he has with thousands of math teachers.
- Des-Blog - it's no surprise that I love Desmos (especially activity builder) and on this blog they are constantly showing off the best stuff created for classroom consumption
- Divisible by 3 - here @Mr_Stadel, creator of Estimation 180, shares out his activities and thoughts including his set of 3Act tasks.
- MathyCathy's Blog - here @mathycathy shares much of her classroom work using technology in the classroom. She's big on Desmos and Nearpod.
- RobertKaplinski - here @RobertKaplinski shares out his work on conceptual ideas in teaching and has a great set of problem based lessons
- Sign of the Times - this blog from @dpscher has conceptual looks at math topics through the vehicle of dynamic web sketches.
- Math Equals Love - if you want a blog where you will see tonnes of resources shared then see what @mathequalslove puts out. Lot's of downloadable resources ready made including interactive notebooks.
- I Speak Math - in this blog @jreulbach shares classroom ideas and math resources from a range of grades and activities and they are tagged by topic as for easy searching.
- Continuous Everywhere but Differentiable Nowhere - if you want some resources and ideas for the older grades then @samjshah has you covered.
- GFletchy - here @Gfletchy looks at the fundamentals of mathematics (especially for the younger grades) with 3 Act Tasks, lesson ideas and don't miss his progression videos.
- MissCalcul8 - do you want ideas for teaching math? Both from a curriculum standpoint and a classroom management standpoint, then @misscalcul8 has you covered.
- Steve Wyborney's Blog - here @SteveWyborney has developed an excellent resource called Splat!. With this you can have students solving equations even in some of the youngest grades. Do not miss this.
- Pi Day - And of course there is Pi Day, I have a Pinterest page collecting links related to Pi that I have been adding to over the years.
