It's always good to hear that the folks at @ONmathies continue to refine and update their apps. The latest is a fresh version of the pattern block app. So now, not only do you have an infinite amount of pattern blocks to use but you have more than the standard blocks (with more to come) but you can now save your work and upload it later. Here is the saved file from this image if you want to try out uploading into your own Patter Block app.

I have long been an advocate of coupling proving trig identities algebraically with verifying them graphically. Now @LukeSelfWalker has had the same idea and taken it to the next level with @Desmos Activity Builder. Check it out.

Using the Desmos table feature as a structure in proving trig identities. Then students see graphs of all of their steps as a way to check to their work. There is a lot of opportunity here to use snapshots in showcasing different paths for a proof. https://t.co/xEGe76HCNX pic.twitter.com/sLaNYrTyHl— Luke Walsh (@LukeSelfwalker) March 19, 2019
Do you want to have your students practice their fundamental skills in an engaging way? Then you might want to use @GFletchy's subitizing multiplication cards. This is an update to his original cardset and includes over 100 cards including some to focus on students moving away from counting.

Here's a neat idea, @MrNiksMathClass has developed what he calls Elastic Band Puzzles where the purpose is to find the sets of values that have the same characteristic. In these three examples it's the zero principal, fractions adding to 1 and factorable trinomials.

These are examples of my "Three Elastic Bands Puzzles" (simple to make, use with any concept, packed with thinking). Pick a theme and create 3 groupings. Then, challenge your kids to identify the groups by drawing non-overlapping elastic bands around each. #tvdsbmath #iteachmath pic.twitter.com/ZdBqLunna7— Math with P.

This data originally came out in 2014 but has recently been updated with 75 new artists. It shows the hip hop artists who have the highest number of words used in their first 35000 lyrics. The data is interactive on the original post and I have pulled out the raw data so that your students can actually use it for some single variable analysis.

Here's a nice video display of some data about the proportion of highest paid artists who are female from @MonaChalabi. It's a simple representation but the animation makes it look so elegant.

Art never seemed like a career that could give me financial security (and good god I want financial security). The fact is, women's art is just valued less than men's art. At best, 7 of the 100 highest paid artists in the world have been women, at worst, just 1. Biiiiiig thank you to @tate and @womeninthearts for commissioning me to do this!

Some interesting looking patterns.

1 + 2 = 3— Ed Southall (@solvemymaths) March 16, 2019
4 + 5 + 6 = 7 + 8
9 + 10 + 11 + 12 = 13 + 14 + 15
16 + 17 + 18 + 19 + 20 = 21 + 22 + 23 + 24
n²+(n² +1)+...+(n²+n)=(n²+n+1)+...+(n²+2n) pic.twitter.com/GMbeh5BpPO
I love this visualization from @MonaChalabi where she looks at the preferred age of date from dating site data. It's pretty interesting how this is split by gender.

Preparing my slides for a talk tonight @nytimes about why I don’t date older men. See second photo 🤮. Source: Data from OKCupid's users, 2014 (tens of millions of preferences were analysed by the site's founder Christian Rudder. I also copied his data visualisation technique here because it works so well). I'm really sorry that there isn't good data on same-sex attraction - will keep hunting!
