Exemplars (from the NaCCA curriculum)

E.g.1: Solve real-life problems on populations. While studying her family's history, Saratu discovers records of ancestors 12 generations back. She wonders how many ancestors she has had in the past 12 generations. She starts to make a diagram to help her figure this out. The diagram soon becomes very complex.
