Math Links for Week Ending Jan. 8th, 2016

I love the way this blog post starts out:
"Last night I decided that it would be useful for my students to have more practice with the graphs of combined functions"
And then @marybourassa creates a Desmos Activity about combining functions, posts it on Twitter for feedback then shares it out. We are truly living in a great time. If this was 10 years ago, that would be just another worksheet. Now it's an interactive activity that has been vetted by teachers from across North America. Seriously, it's a good time to be a math teacher

We have been posting a few "Tower Challenges" on our Engaging Math Blog. They are all review assignments where students answer questions to accumulate building materials to create the tallest tower in the end. Here is one for grade 8 on Algebra and Equations.

I have created a new post on my Found Data blog. Here I blog about data sets that can be used to teach statistics. On this latest post the data is real-time info about earthquakes and is good for any single variable analysis.

I always love calculus activities and although this is not an "activity" per se, I love the simplicity of the beginning with this rate of change worksheet. Download at the link below and as the commenter suggested, also try out the @Desmos activity Waterline.

I thought this was a nice little review for what the solution for a system of equations was from @DaneEhlert. Good use of the football video we have (hopefully) all seen.

I really like this new video from @numberphile on the iPhone of the sliderule. I honestly never really considered how they work but you could easily incorporate them in your classes when dealing with estimation.

Dang, I missed Right Triangle Day! Dec 9, 2015 (12/9/15). I wonder when the next right triangle day will be?
