  • Read and discuss the sample comic.
    • Have you ever gone on a road trip? 
    • How many miles do you think you traveled? 
  • Review rounding. Have students solve Emily’s rounding problems as a class.


  • Using the sample comic as a guide, have students create their own "Rounding" comics. 
  • Have students choose a number with decimals to the ten thousandths place.
  • The four-panel comic should include: 
    • Panel 1: Should describe a real life scenario where rounding can take place, e.g., crowd size at a football game, miles flown in a year, number of candy bars sold in a candy store, etc.
    • Panel 2: Students will share their number and explain how to round it up or down.
    • Panel 3: Students will round to the nearest tenth.
    • Panel 4: Students will round to the nearest hundredth.
    • Panel 5: Students will round to the nearest thousandth.


  • Have students share their finished comics with a partner. Is their partner comic accurate?


  • Allow students to use the speech-to-text feature.
  • Allow students to use the voiceover feature to read their comics aloud.
  • Allow students to work in pairs or groups as needed.
