" 'I don't do maths' is often said as a badge of pride, as though it excuses any personal responsibility. Yet, as job seekers, you say it at your peril."

A handy excel spreadsheet that has been formatted already, ready for action. Thank you Johan!

I am just busy catching up on some old bookmarking of ML research articles

Bess's 2011 grade 11 final papers

In this activity, students conduct an investigation to determine the rate of change in the popping of microwave popcorn. Four volunteers will estimate the time in the popping process where the rate of change is at 5 chosen levels. Other students will collect data on number of pops during consecutive 5 second time periods and draw histograms. Students will understand the approximate normal curve for a real data set and the relationship between the rate of popping and the shape of the distribution. This activity also provides an opportunity for students to understand human errors in data collection because not everyone will have the same number of frequencies in the corresponding classes of their histograms.

This simple Investigation, I did in the first term. It is not difficult to complete for the learners, but it takes a while to complete because they had to go out and "get" the answers. However, it went well because i actually had a 100% handing-in rate, which is always good.

Students will learn about daylight. They will collect data on sunrise and sunset in the town or city where they live.  They will understand the data pattern and offer a hypothesis about  the reasons that the amount of daylight varies during the year.

A simple guide to understanding basic statistics, for journalists and other writers who might not know math.

I have read the attached article in Die Burger of 10 August 2012. The article confirms the  urgent need for the teaching of mathematical literacy. It strengthen the view that if a person can do and understand maths he or she is not necessarily mathematical literate or numerate.
