This lesson teaches how to draw arrays using repeated addition sentences. It explains how to interpret number sentences and create arrays by drawing columns and rows. Two different arrays are drawn from the same repeated addition sentence, demonstrating the flexibility of array representation. The lesson concludes by summarizing the key points and reinforcing the concept of arrays in mathematics.
