I’ve written about wodb.ca in my post: Make Reasoning a Routine
Provides over 200 image based growing (and shrinking) patterns for students to determine how the pattern is growing, and how many items would appear in a given future image.
I’ve written about visualpatterns.org in my post: Make Reasoning a Routine
Lots of various dot and actual photograph images to support all kinds of operations. Also has great further resources for making number talks differentiated to your own class.
Many problems, Pre-K to 12, structured by students filling in blanks with digits from 1 to 9 to get a certain type of answer. Gets students to reason as well as practice skills and mathematical thinking.
A collection of GIFs which can be prompted simply by “What do you notice, what do you wonder?” The blog also gives instructions on how you can make your own dynamic gifs using DESMOS. Just wonderful. Can’t wait to explore more.
A great collection of images that beg our students (and us) to use our numerate skills and take some risks by estimating some often quite challenging quantities. The low floor and high ceiling is built in as all images come with space for you to enter a guess that is “Too High” one that’s “Too Low”, your actual “Guess”, and your reasoning. Most images also include the actual, real life answer so that we can reflect!
This blog is a collaborative effort by teachers who are seeking to experiment with their own questioning styles, and they’re documenting the journey for us! This is probably my favourite post on reversing homework questions…love it!
Desmos as a dynamic graphing calculator is pretty awesome, but this platform for building activities is amazing. Push an activity out (either from stock or self generated) and watch your entire class progress through questions, graphing, drawing on the screen by hand, and working off of each other’s progress… it really will turn your class into a work of art.
Great ways to get students to start and develop their algebraic thinking. Students work with the “balanced equation” structure to try to solve various puzzles. The website is growing daily, and more and more interesting puzzles are being added. Have fun!
This is an oldie but a goodie by Dan Meyer. A series of videos where the independent variable is time, and the dependent variable is…well anything…including the height of your bum off the ground as you go down a water slide. Comes ready with a handout for students, and discussion questions.
This is a Twitter account which posts great visual proofs and queries at a fairly fast pace. Very interesting take on some great math content which begs us to ask our students “What do you wonder?” and will I think empower many of our students to show their thinking using GIFs down the road.
This was my bible when I started re-thinking how I teach. It’s filled with ready made gems of 3-Act math tasks which cause curiosity, encourage divergent thinking, and are inherently low floor/high ceiling. Dan Meyer is a master of finding opportunities for us to make all of our students feel the love. If you’re hesitant about any of these…just try them…they’ll change your life.
A great website and twitter account (@FractionTalks) that asks teachers and students to estimate ratios/fractions/percent with regards to spacial reasoning as well. A fun way to start a class, and a great daily reasoning routine. Encourage students to sketch, estimate, think, argue…really anything but measure. Have fun!
This is a fantastic collection of contextual problems that can range from K-12, and that can be done as a minds on, all the way to multi lesson, over-arching problems. A great way to get students to, again, estimate, think, reason out, and apply math. Thanks to @robertkaplinsky for the work!
Want your students to fight??? About math that is! Agree or Disagree is a pretty young site, so not a tonne of resources, but a great idea which you can consider contributing to. Pit your students against each other, and watch the math talk fly!
