Math Links for Week Ending Apr. 14th, 2017

Though still in beta form it's pretty cool that Desmos has started to move into the dynamic geometry area. It's not so much that we need another dynamic geometry platform (Geogebra and Geometer's Sketchpad are already awesome) but, hopefully, this will mean that soon we can incorporate dynamic sketches into Activity Builder. Right now, however, you can just play around, there are just a few building tools and you can't save your sketches. But who knows where this will lead. It didn't take long for me to make something simple (below) that shows some mathematical properties. Thanks to @dpscher for pointing this out.

When I saw Splat for the first time as a friendly way to solve equations. I loved how it could be used for just about any grade. And now @SteveWyborney has put out slides for Splat with Fractions. So good. Watch the how to videos and download the PPT files.

"I've felt like I'm always assessing" - says @MrOrr_Geek. As a teacher I think, if you are doing your job, then that has to be true. In his latest post about connecting formative assessment and 3Act tasks. Some of the best assessment you can do with students is formative. Take a look at this post for some insights as to how to handle it

Two Easter themed activities from our Engaging Math Blog. Both are review activities. One is for analytic geometry and the other for proportional reasoning. It's a good time to stock up on those plastic Easter eggs from the Dollar store

I tweeted this out a couple of weeks ago but forgot to add it to the weekly links. It's @standupmaths doing the math behind the double domino. I didn't know that this was a thing that could happen and was surprised at what happens - you will be to Great for connections to similar triangles, ratios and Pythagorean Theorem.

And I was so inspired by it that I did my own double brick experiment. As you can see at the end, I was quite proud of the result.

Ooh I like this one. A cool fraction question dealing with areas of triangles.

Having kids make inferences from graphs is important. The inference I see here is that my Mac is getting less secure.
