Lesson Plan

Before the Lesson
Before teaching this lesson, you might want to review math word (story) problems with students. Talk about key words students might read in a problem that will help them decide whether to add or subtract.

Lesson
Provide students with a copy of the BIG Pumpkins work sheet. Talk about the chart with students before asking them to solve the problems. If this is their first experience this year with word (story) problems, you might have students complete the work sheet with a partner. Otherwise, let them solve the "big pumpkin" word problems on their own. (See the Answer Key in the Assessment section below.)

Extension Activities

• Teach the concept of "rounding numbers" by having students round off numbers on the work sheet to the nearest hundred pounds.
• Challenge students to create a picture or bar graph to illustrate information on the chart.
• Teach the concept of "tons."
• Share with students photographs of some very large pumpkins:

Have them write a story about the day they woke up to find that overnight a 1,300-pound pumpkin had grown in their gardens!
• Have students make up their own word problems about the chart.

Assessment

Students will correctly solve at least four of the five word problems.
ANSWER KEY: 1. 76 pounds; 2. 2,600 pounds; 3. Dave Stelts's pumpkin weighed 9 pounds more; 4. 3,752 pounds; 5. 63 pounds. Challenge Question! The pumpkins weighed 12,161 pounds, which is close to 6 tons.
