Materials

  • Copies of "Our Great States" booklet (pages 10-14)
  • Copies of "Great State Word Problems" worksheet (page 19), or use overhead
  • Scissors
  • Stapler
  • Yellow crayon for each child
  • Crayons (optional)
  • Slates or individual boards for each child (or several sheets of paper)
  • Overhead projector (if needed)

Preparations

  • Read over the lesson.
  • Make "Our Great States" booklets (pages 10-14).
  • Make overhead of "Great State Word Problems" worksheet (page 19), if needed.

Worksheets and Files

Lesson plan, worksheet(s), and rubric (if any) at www.usmint.gov/kids/teachers/lessonPlans/300-305.pdf.

  1. Hand out copies of the "Our Great States" booklet (page 10-14).
  2. Read through the booklet as a class and have students highlight with a yellow crayon significant dates and numbers.
  3. Hand out slates or individual boards (or use paper) for each child to work on. (If you wish, you can pair students up for these activities).
  4. Read "Magnificent Math!" (page 18) aloud.
  5. Make sure students understand how to extract the missing information from the problem.
  6. Ask students to solve each problem on their slate or paper. Check for accuracy.
  7. Pass out the "Magnificent Math!" worksheet (page 19). The students will be assessed based on their ability to correctly solve four word problems using information from their "Our Great States" booklet. Students will also create their own word problem using data from their own lives.

Enrichments/Extensions

  1. Have students write word problems about their own lives, creating addition and subtraction problems to go with them. These word problems can be compiled into a class book.
  2. Students can search for significant dates and numbers in their own state's history. Using this information, they can write a collection of word problems for another class to complete.
  3. Using family information (birthdays, ages, addresses, telephone numbers, etc.) students can create word problems to share with the class.

Assess the students' ability to correctly solve four word problems using information from their "Our Great States" booklet.
