Product Description
This project is written to be an in-class project but can be adapted to be an at-home project. The packet includes a teacher instructions page, a Shel Silverstein poem, instructions for the student, an example that has been fully worked out, student answer document, summative thinking questions, and an early finishers / extra credit assignment. I have included the text from the first page of the packet below that explains the objective and procedures, and gives an overview of the project:

Objective: The student will be able to set up proportions and solve them to answer real-world problems.

Overview: Students will measure their current height and pretend they are now 100 feet tall. Students will measure the height or length of various objects and find their new height or length in “Big World” by setting up a proportion, using the ratio of their current height to their height in Big World.

Materials: “It’s a Big World” project handouts, yard sticks or measuring tapes

Procedure:

1. Introduce project by reading aloud the Shel Silverstein poem, “One Inch Tall”. Have students follow along in their project packet.
2. Read aloud the page that begins, “Imagine if one day we …”
3. Pair students up and have them measure each other’s height in feet. Students record their height in the box.
4. Have students convert their height from feet to inches and record this in the box, as well.
5. Go over the coffee cup example as a means of reviewing proportions and previewing the project expectations.
6. Review the grading rubric with students so that they understand how they will be assessed.
7. Students begin working individually or in pairs to measure the heights or lengths of various objects. They then use the ratio of their current height to their height in Big World to set up a proportion. They solve it to find the heights or lengths of their objects in Big World. All measurements and proportions are recorded in their packet. Remind students to show all of their work. They also convert from inches to feet, as needed.
8. Independently, students answer the Thinking Questions as a project wrap-up.
9. Early finishers may work on the extra credit assignment at the end of the packet.
