I love some of the little and simple activities that Desmos is building using Activity Builder as their backbone. Here are a few that they have released recently.

This first one is on solving equations. In general, solving equations is not a very engaging activity but here they have given students a challenge. Create an equation that has a solution closest to zero. And because of some of the Desmos only features it is pretty interactive.

The next one is on solving systems of linear equations. It starts really harmlessly by asking if there are any numbers that have a difference of 8 and a sum of one. Again, by using some of their tools you get interaction and then when they start entering their choices you get graphical representations to lead directly to the intersection of two lines.

Finally a card sort and questions that help distinguish between linear and non linear relations. It is not that long (like the others) but incorporates challenges that help solidify concepts for students.

And I guess this is a bonus one from @ddmeyer. I love the video series that this one on graphical intersection is based on this cool football footage. They have made it into a nice Desmos activity of course.

Can you help me with a new problem? What do you notice? What do you Wonder? #mtbos #mathchat pic.twitter.com/xWJkLVXXpg— Jon Orr (@MrOrr_geek) December 8, 2016

I love this one from @Errs5. I like it because you can do it and not know anything about the area of a circle.

.@ddmeyer Is the area of the yellow less than the area of ONE circle, equal to ONE circle, or more than ONE circle? please RT pic.twitter.com/cJ52QSai8L— MathDDSB (@Errs5) December 5, 2016

Something nice and simple on multiplying decimals from @Danluevanos after a request from @robertkaplinsky.
