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— Zach Korzyk (@MrDeltaMath) January 9, 2020

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.

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.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— Luke Walsh (@LukeSelfwalker) January 7, 2020

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— Luke Walsh (@LukeSelfwalker) January 7, 2020
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.Curriculum Tags: Gr7, Gr8

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.Curriculum Tags: MHF4U

There is a new activity released from @Desmos to introduce the idea of dilations. Only 8 slides but nice and interactive as you would expect.
