Here are a few of my Grade 4 learners. I've been doing better and better with them (probably because of the small class size--18 learners), while I've been doing worse and worse with the 5/6 class (31 learners). The profound-looking one is Reaobaka, while the eager short guy on the left (who's the best at maths) is Obenne. On the right we have Thataone, and in the back Kobamelo on the left and Kaone on the right.
A teacher friend tells me that the key to classroom management is finding what your kids love and taking it away if they won't behave. They certainly love me taking their picture, and if I could print it out somehow I think they'd be ecstatic. Certainly worth considering.
