Subject: Math

Lesson Length: 30 - 40 mins

Topic: Numbers and Operations in Base Ten

Standards / Framework:

Brief Description: In this lesson, students will round decimals to a given place value.

Know Before You Start: Students should have some experience with rounding. This serves as a great informal assessment to gauge student understanding.

Hook:

• 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.

Activity:

• 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.

Closure:

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

Differentiation:

• 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.
• Adapt the lesson to use Metric measurements.
