hook:

The first time through the video, some kids were talking.  One girl yelled, “¡cállate! This looks interesting!”
So I started it over.

I had a random kid get out his phone and start his stopwatch.  Zooming out from the horn, I wrote the number 1,250,000 on the board, and asked them what they thought that number meant.  After a few guesses I told them it was the number of  children who die per year of hunger related causes.  Since many of our students really lack basic maths skills, and this is a math enhancement class, I had them figure how many died per month, then asked about the total for the last 3 months – since that’s the time period the video highlighted.

We talked about how slope is a rate of change, so if we wanted to find the rate children die per week, we’d have to find out how many weeks there had been in 3 months, which we put on the x-axis.  We put 312,500 at the top of the y-axis, and figured the rate of change.  We repeated this for days, hours, and minutes.  They did a really good job!

At the end, we figured how many had died while doing this problem, based on the stopwatch time.  I told them for every A & B on tomorrow’s test, I’d donate \$2 to UNHCR.

I had this slide ready in case they asked me where the Horn of Africa was. If nothing else, now they know Africa is not a country.
