Learning activities:
Activity #1: Choose 2 people from your life (example: mom and dad) and think about as many differences as you can between them. Make sentences about them using comparative adjectives. For example: My mom is shorter than my dad.
Activity #2: Work in Pairs. Using superlative adjectives, make questions for your partner. For example, what is the quietest place you can think of? Where is the tallest mountain? Who is your nicest friend?
