I have liked a lot of the stuff that @SteveWybourney produces (my favourite is still Splat!). This year he has produced an e-book of his top 20 teaching tips. Though this is not a resource about mathematics, it does have some great ideas for general classroom practice. I won't give them all away here (you have to sign up at the link below) but I will tell you these are tips in the form of small things that you can do to help your relationships with your students. I will tell you one of my favourites and that is to "Tell a Story". I have had a lot of contact with this idea lately. First I saw it in a book called Weekend Language (recommended to me by @GFletchy) where the premiss is that if you want to give compelling presentations that "stick" then rather than have flashy graphics and dynamic slideshows, all you need are good stories (think: the way that we spend the weekends talking to our friends). Another way that story has come was during a recent interview I did for the @OAMEtalks podcast. I interviewed @RichardVanCamp and he spends the bulk of his time telling stories and we talked about the importance of story in education.

A new activity from @Desmos for describing transformations. And at the end there is a challenge creator for students to create their own transformation with a polygon.

Here's a nice dynamic resource from @Brzezinski_Math regarding radian angles and the circle. It's good practice for your students since it generates as many random practice questions as you need.

Here is the math your students actually need to know now:

"Now that everyone has powerful computers (like that smartphone in your hand), we should teach math as if computers existed.
Now that everyone is an entrepreneur, we should teach financial literacy (make it a graduation requirement like Missouri).
Now that we all use probabilities all day long in life, work, and leisure, we should teach statistics and probability.   
Now that every field is computational, we should invite youth to attack big problems with big data sets (that’s called data science)."

There is no secret of my love of Desmos so I'll start with couple of announcements. One is a new activity and the other is an opportunity. First, the new activity about scientific notation. It's a relatively short activity but it has nice visuals and has some student choice involved.

I like this activity from @emergentmath. It's about transversals and parallel lines. It starts with a favourite strategy of mine called concept attainment where students see examples and non examples. But the crux of the lesson is a simple activity that relates to a real map of streets. We could probably all do a similar activity using a screenshot of the streets in our own town.

I always appreciate how @MissCacul8 takes a math concept and puts some bling on it. In this case it's her kids doing a project on the unit circle by having to make a representation it. It seems simple enough but click on the link and see what her kids did. So many pies and cakes.

I've always been a fan of Open Middle problems. I think that they give students the licence to be correct with more than one way of doing things. And you can certainly get some open middle problems at the https://www.openmiddle.com/ but now @RobertKaplinski now has released the Open Middle book. This has all the info you need to get started and learn how to facilitate those types of questions.

It looks like @MrDeltaMath has been busy. If you have not ever looked at his site, you are really missing something that could help your students work through problems. In this case he's gone through geometry proofs but there are so many other dynamic solutions on this site for other math topics it won't matter what you (or your students) are looking for and as a bonus, it's free.

Happy to announce that I have finished the Geometry Proofs section on DeltaMath. It took 7 months, but I manually created & inputted 350 unique proofs and students can prove any way they choose. Lots of scaffolded modules too. Please share w/ Geometry teachers! #iteachmath #mtbos pic.twitter.com/o4HQoNAN3R

This is a fairly simple set of slides from @LukeSelfwalker students are asked to choose the smallest number from the list that no one else has chosen. The display of the class's data shows up as a dot & box and whisker plot. There could be a lot of places for discussion here. From the strategy for choosing a value to the way the data is organized.

For a day oneish type of activity, I created a few slides of "Pick the smallest number that no one else picks." The idea is bring up how student engagement is vital to our daily classroom activities and how we can learn from what other people contribute.https://t.co/CCE33jteLI pic.twitter.com/Bed4ev27Zj

Here's another great one from @LukeSelfwalker. This time its estimating radian angles. Such simple but effective practice and I like how he has students reflect at the end on how much they have done.

5 different slides for practicing angle measurements on the unit circle. I purposefully chose not to track how many are correct. Starting to think how correctness during practice is privacy for students.https://t.co/04vrPnjiNG pic.twitter.com/ST6Qxg11RF

I am a big fan of simple games that help reinforce math concepts. In this case it's probability based with this simple sum game with two dice. @MBurnsMath does a great job of explaining it and despite the fact that it starts out as an activity for grade 2 students, there are definitely ways to have older students use it as a math starter. Thanks to @MarkChubb3 for pointing out this one.

Though this activity from @mathface22 is long, it provides lots of practice and for students who are learning to sketch polynomial functions. I like how it allows you to trace out the function you think represents the equation and then shows you the correct graph.
