Building a paper bridge: An introduction to problem
solving
This activity allows the student to explore problem solving strategies while working with a partner. This activity
(building a paper bridge), requires students to question word definition and the application of those definitions.
Through problem solving strategies, students discover the need for applying math skills.

Super Bridge In this Nova activity students play the role of civil engineer to decide where to build four
bridges. This is the website to use: http://www.pbs.org/wgbh/nova/tech/build-bridge-p1.html
Learning outcomes
Goal: The student is to build the longest non-supported single span bridge possible using one sheet of 8.5 × 11
paper.
Objectives:
1. Students will explore a variety of ideas to solve a simple problem
2. Students will creatively find means of measuring materials to construct a paper bridge
Teacher planning
Time required for lesson: 45 – 90 minutes
Materials/resources
Each student group will need the following:
1 sheet of paper, 8.5 × 11 (although any size will work)
12 inches of masking tape
1 pair of scissors, pencil
Pre-activities

Pass out the handout titled Problem Solving Activity: To Build A Bridge (see following document)
Go over the activity with the students.
Group students into pairs.
Students should begin sketching ideas on the bottom of the Problem Solving Activity page.
Pass out to each group the following materials: 1 pair of scissors, 1 sheet of paper, 8.5 × 11, 12 inches of
masking tape. Students should have their own pencil.
6. As soon as students receive their materials they can begin construction of their bridge.
Assessment
1. Review the problem statement. Ask students for the definition of key words such as span.
2. Ask for students to display their bridge and show the span of their bridge. This is a good place to discuss
the meaning of “longest non-supported single span”.
3. Determine which group built the longest single span bridge.
PROBLEM SOLVING ACTIVITY - BRIDGE BUILDING
You will need a partner for this activity!
Goal:
Students are to build the longest non-supported single span bridge possible using one sheet of 8.5 x 11
paper.
Materials:
1) 1 sheet of paper, 8.5" x 11"
2) 12" making tape
3) 1 pair of scissors
4) a pencil
In the space below sketch 3-4 possible solutions for your bridge. You and your partner will need to
select one solution to try.
