What's Going On In This Graph?

The New York Times runs a weekly online article called "What's Going On In This Graph?".  It is a great opportunity to engage your math/science students.  This one I have chosen would be great for your math students studying finance, loans, amortization etc.  To see the article click here.  To see previous articles click here.  Below is a graph of another article they have students compare a graph of the age of first-time mothers in 1980 versus a graph in 2016 and compare.

Photomath

From their website, "Photomath is a mobile application described as a "camera calculator", which utilizes a phone's camera to recognize mathematical patterns and to display the solution directly onscreen. It is available for free on Google Android and iOS"

I have utilized this app on my phone and it works well with typed questions and even on my hand written questions.  Not only will it show you a solution but will show you the steps used to get the solution algebraically and graphically.  This works from basic arithmetic through trigonometry and Calculus.  To see the webpage click here.  The downloads can be found for iOS by clicking here  and for Android by clicking here. 

NY Times - What's Going On in This Graph

Here is a bonus post for today.  Yesterday the New York Times announced that they would publish monthly, "What's Going On in This Graph".    According to their website, "Teachers tell us these data visualizations are rich texts for classrooms across the curriculum, not just in the math or statistics class. Whether in a literature class analyzing Jane Austen’s language, a science class considering climate data, or a civics class studying gerrymandering, teaching students how to read, interpret and question graphs, maps and charts is a key 21st-century skill."  To see the website click here.
