“Students review and extend important language for learning English, including how to say some letters of the alphabet, ask questions about language and identify parts of speech. The lesson includes an interactive game to test mastery of the content, which can be played in both online and face-to-face contexts. There is also a short optional extension activity about the NATO alphabet.” by Stephanie Hirschman.
