Jim Siegel and Chelsea Corcoran/Quadt give an example in which children explore the career of an endangered species biologist by participating in a hands-on population survey. By conducting a survey, utilizing their math skills, to estimate the number of endangered animals left in their area, children will experience first-hand the real work that people do on national wildlife refuges near them!
