What’s Going On in This Graph?

 

I guess it has been a bit since I posted something about my first teachable of mathematics but here is one for you if you are teaching data analysis, data management or just want to have students interpret graphs.  Not y = f(x)  graphs but data driven real data graphs.

Chart It

 

Do you need to make a chart or graph?  You might want to consider Chart It.  It is free and offers Geo-Charts too.  Simply paste data directly from Excel, csv or text.  To see their website click here.

Straight Line Graphs

From their website, "Maths teacher Kathryn Hurrell, at Comberton Village College, helps her lower ability Year 9 pupils understand straight-line graphs by turning the mathematical concept into a practical activity.

Kathryn gives groups of pupils some simple y=mx+c equations and they work out pairs of suitable coordinates and stand at that point within a large scale set of axes on the classroom carpet."
