She wasthe first American woman to win threegold medals in one Olympic Game. Born in a poor family, young Wilmawore a brace on her left leg. Back then it was easy to discount her chances forsuccess. But Wilma was not discouragedby her disability. She took off her braceevery time she could. As her legs grewstronger, her discomfort disappeared.Her talent left others in disbelief. Today,Wilma Rudolph is remembered as one ofthe top athletes of the twentieth century!

English-Language Development StrategiesChoosing Prefixes

English-language learners may be confused by the altering of word meaningsby adding prefixes. They may also have trouble deciding when to use one oftwo similar prefixes, such as dis- and un-. To practice, write base words onthe board and ask students to give the correct prefix (happy [un-], agree[dis-], comfortable [un-]).
