1
Warm-up: Who is it? (5 min)
Display the first slide. Read a sentence aloud and ask students to point to or name the person the pronoun is talking about.
"Mrs. Smith dropped her chalk. Who does 'her' refer to?"
2
Video & Key Discussion (10 min)
Pause points for Khan Academy video:
0:22 (Etymology) : Ask: "What does 'Ante' mean?" (Before). Can they think of other 'Ante' words?1:20 (Gender) : Ask: "If I replaced 'She' with 'He,' would the sentence still make sense? Why not?"2:10 (Prediction) : Pause after "The monkeys threw snowballs." Ask: "What word will we use to talk about the monkeys in the next part?"3:10 (Correction) : Ask: "Why does using 'it' for 'monkeys' create a confusing mental image?"
3
Main Activity: Antecedent Match-Up (20 min)
Divide students into small detective agencies (groups of 3-4). Give each group a set of Sentence Clues and Pronoun Cards .
Students identify the underlined noun (the antecedent).
They must find the matching pronoun card based on gender and number.
Circulate to check for common errors like using "he" for feminine names or "it" for plural animals.
4
Closure: Quick Fire Round (5 min)
The teacher shouts a noun; students shout the pronoun that should replace it.
"The dogs!" → They
"Grandpa!" → He
"The pizza!" → It
"Sarah!" → She
Watch Out For
Gender Confusion
Proper names can be tricky. Use clear examples (Jillian) and remind students that the pronoun must match the identity of the person.
Number Mismatch
Using "it" for groups of objects or animals is a common 3rd-grade error. Emphasize that plural nouns (ending in -s) always need plural pronouns (they).
