From 2nd to 17th May is Fair Trade Fortnight – a World Vision campaign aimed at making people aware of the impact of what and when they buy – it’s about primary producers getting a fair deal, without exploitation. The Fair Trade certified label provides an independent guarantee that the products you buy are supporting families to lift themselves out of a cycle of poverty in developing countries. A product must meet stringent fair trade standards before it can display the label. Fairtrade products currently available in Australia are: coffee, tea, chocolate, cocoa, nuts, sports balls, rice, quinoa, sugar and cotton.

Landline have an interesting video about cocoa growing in Papua New Guinea.

Initially some students believed that just a few more than 70 should suffice, while others decided the more the better and thought a few hundred should be added – just to make sure! After coming up with some ways to use random number generators to model the problem (10-sided dice, cards, throwing stones on a 2 x 5 grid) we used the Maths300 software to generate a stem and leaf plot for 100 trials. Following the activity, students estimated that between 110 and 150 chocolate buds were sufficient to have confidence that each cookie contained 7 choc buds. And now they want to make cookies…..
