Try giving medicine to llamas - there's no chart. Although it's basically a simple ratio calculation, since there are no meds dosed by the mfgrs specifically for llamas they are all "off label"and it gets tricky. In using meds labeled for sheep or horses you have to convert from the label dose in milligrams or the number of "clicks" for gun dispensers for the weight of the other livestock, then take into consideration the guidelines on a llama's physiology needs compared to the other livestock, then calculate the dose based on the weight. It can get SO confusing unless each step is written down and combined into one equation to give the # of clicks or milligrams to give for the llamas weight. Someone without math skills has to call the vet and ask. Then how can they possibly check the vet's advice for accuracy??
I've mentioned this thread to several people. They all had the same response: it would be irresponsible to drop or reduce math instruction; what's desperately needed is MORE math in public schools.
