The document discusses five energizing activities to boost vocabulary production and retention for second language learners. It recommends having students create stories and songs using target vocabulary words from weekly class lists. This allows students to practice using different aspects of word knowledge, like meaning, collocations, grammar, and appropriateness, in longer oral and written pieces. By producing language in context to achieve a communicative goal, this activity can facilitate retention of vocabulary through deeper internalization of word knowledge. Students also find the task fun.
