Learning Activities

  • Sexually Transmitted Infections (essential)

    Time: 30 minutes



    • Inform students that today they will be learning about the risks of sexual activity so that they can make responsible and informed choices regarding their sexual health
    • Deliver PowerPoint presentation, using prompts in presentation notes to conduct discussion throughout presentation, if desired
  • STI Bingo

    Time: Approximately 30 to 40 minutes



    • Ask students to name a few examples of sexually transmitted infections and record responses on available board
    • Tell students that they are going to play a game that will review facts about sexually transmitted infections
    • Distribute STI bingo boards to each student. The boxes on the boards contain words relating to sexually transmitted infections, their transmission and prevention. Each board is different.
    • Tell students that statements will be read aloud that relate to sexually transmitted infections. Students will work individually or in pairs to determine the response to the statement and then share it with the class. Once a correct response is provided, and it appears on their bingo board, the participants will mark it off with a marker or dabber.
    • Use the STI bingo statements to read the statements aloud. Statements can be read in numerical order, or have students choose a number from 1 to 28 to pick a new statement.
    • After each statement is read, give students a moment to think of a response (individually or in pairs) and share with the class
    • Give the students a time to find the correct response on their STI bingo cards and mark it off
    • The first person to have five boxes crossed out that line up horizontally or vertically and calls out "BINGO" will be the winner
    • If the game ends quickly, explain that the next winner is the person with all the boxes on the STI bingo board crossed out
