Procedure
	The actions of students and teachers and the interactions among and between students and teachers:

Students will brainstorm, with teacher guidance, questions regarding the cathedral (or church).

Students will be assigned to cooperative groups based on interest areas and be given certain questions to answer by the end of the week. (Prior cooperative group work is essential for this project.) Students will make some predictions and estimations regarding questions.

Group 1:
• Tight Squeeze. How many people fit in this church? Develop a plan to estimate the number of people that could fit in the church at one time. Show your steps. Implement the plan and show a solution.

Group 2:
• Tally-Ho. What can you tell us about the stained glass windows? Tally the patterns, the colors, the shapes and the sizes of the stained glass windows. Make a graph. What is the purpose of these windows in the church?

Group 3:
• Go on a Shape Hunt. What shapes do you find? You may observe all aspects of the church except the glass windows. Are there more of one kind of shape than another? Show how you came to your conclusions.

Group 4:
• Go on a Number Hunt. What do the various dates in the church mean and what do they tell us? Which building is older, the church or the school? Where do you see numbers in the church? Find them, read them, tell us about them.

Group 5:
• Skinny or Fat? Is the church longer than it is wide? Why is it called a cathedral?

Group 6:
• If I was a church mouse.... Is it farther to walk to the church or to Pudgies Pizza from our school?

Students will walk to the church bringing with them their questions and materials needed to do on-site observations.

Six parents will accompany students on the field trip to the church. Each parent will be responsible for three to four students. Parents will be prepped beforehand concerning expectations of the trip.

The teacher will circulate inside the church to facilitate the questioning, observation and research processes.

Students will record their findings using the worksheets which appear at the end of this lesson plan.

Calculations and problem solving will occur next. The teacher will use parent volunteers or 5th and 6th grade "learning buddies" to facilitate problem solving back in the classroom. Tasks involved in problem solving are recorded as performance indicators in Mathematics at the beginning of this lesson plan.

Students make journal entries throughout the week to record impressions of the experience of the field trip, the tasks and mathematics involved, and further inquiry questions.

Students, in cooperative groups, will present information gathered during the week to the whole class on Friday. Parents and other visitors will be welcome.
