Although we did not use it today, the Lesson 21 PowerPoint is available for download. Instead, we jumped into the Salty Eights game, with students working in groups of four to create and name ionic compounds. Compounds created by individual students were recorded on the Lesson 21 worksheet.
After completing the game, students had the remainder of the class period to work on the Lesson 21 homework: questions 4-8 on pages 107-108 in the textbook.
