This comprehensive notes sheet / packet reviews all types of commands, including affirmative tú, negative tú, Ud. commands, and Uds. commands. After each section there is a set of practice conjugations for the students to complete. It also includes a fun mnemonic device, and a large side-by-side comparison chart at the end that helps them tell the difference between all the types.
While designed to accompany the Realidades 3 textbook (Ch. 3), you can use these notes to review commands with your students REGARDLESS of your textbook/curriculum!
