African Safari
Adventure
Math Story by Claudette J. Young
Kit and Matthew began their African safari at the watering hole. They had two
days to see all the wildlife they could. Their parents and the guide kept them safe.
The first morning ten elephants claimed the waterhole
for their morning bath. Soon Kit counted eighteen zebras
coming for water. A dozen baboons wandered in and started making noise and
acting silly. Matthew laughed hard and loud at their antics. His noise sent five zebras
running off.
The next day everyone rode into the bush. They paused to
look at a lone rhino standing in a clearing. While they were
looking, the rhino began to charge them. Kit and Matthew
screamed, but the guide drove them to safety.
Further on they found a pride of eight lions dozing under an acacia
tree. Above the lions played twenty-two monkeys in the tree.
Matthew and Kit saw a giraffe with a baby standing beside a tree. The giraffe
stretched to reach its food with its tongue. A trio of jackals moved nearby to threaten
them. The jackals ran out of sight when the jeep came too close to them.
Everyone was tired. They’d seen no leopards, or hyenas, or cheetahs. Lions
hadn’t roared, but a rhino had threatened them. What an exciting adventure they
had!
