Title: Foldable Activity: Rational, Integer, Whole, and Natural Numbers

Grade Level: 7th Grade Subject: Mathematics

Objective: - Students will be able to differentiate between rational, integer, whole, and natural numbers. - Students will create a foldable to organize and label examples and non-examples of each number type.

Materials: - Google Slides presentation - Paper or cardstock for foldable - Scissors - Glue or tape - Markers or colored pencils

Procedure:

1. Introduction (5 minutes):
   • Begin the lesson by asking students if they can define rational, integer, whole, and natural numbers.
   • Explain that today, they will be creating a foldable to help them understand and remember the characteristics of these number types.
2. Google Slides Presentation (10 minutes):
   • Share the Google Slides presentation with the students.
   • Go through each number type (rational, integer, whole, and natural) one by one, providing definitions and examples.
   • Include visuals and interactive elements to engage students.
3. Foldable Instructions (5 minutes):
   • Distribute the paper or cardstock to each student.
   • Instruct students to fold the paper in half horizontally, creating a top and bottom section.
   • Then, have them fold the paper in half vertically, creating a left and right section.
   • Open the paper and fold it in half diagonally from the top left corner to the bottom right corner.
   • Open the paper again and fold it diagonally from the top right corner to the bottom left corner.
   • Students should now have a foldable with four sections.
4. Creating the Foldable (15 minutes):
   • Instruct students to label each section of the foldable with one of the number types: rational, integer, whole, and natural.
   • On the top flap of each section, students should write the definition of the number type.
   • On the bottom flap of each section, students should provide examples and non-examples of the number type.
   • Encourage students to use different colors and illustrations to make their foldable visually appealing.
5. Sharing and Review (10 minutes):
   • Allow students to share their foldables with the class.
   • As each student presents, ask them to explain their examples and non-examples, ensuring their understanding of the concepts.
   • Summarize the key points and clarify any misconceptions.
6. Conclusion (5 minutes):
   • Review the definitions and characteristics of rational, integer, whole, and natural numbers.
   • Emphasize the importance of organizing information visually to aid understanding and retention.
   • Collect the foldables for assessment purposes, if desired.

Extensions: - Students can create additional sections in their foldable for other number types, such as prime numbers or even/odd numbers. - Students can research real-life applications of rational, integer, whole, and natural numbers and add them to their foldables. - Students can work in pairs or small groups to create a collaborative foldable, combining their knowledge and examples.

Note: Adapt the time allocated for each section based on the pace of your class.
