9. Teacher Notes Standards:
3.5.1 Measure line segments to the nearest half-inch.
Find the perimeter of a polygon.
Goal:
I want my students to understand the importance of being able to measure. They should realize that measuring is used all the time in the real world. It is also important to use a standard unit when measuring and be able to measure to the nearest half-inch. I also want my students to be able to find the perimeter of polygons and understand what the measurements could be used for.

11. Teacher Notes Instructions for the teacher:
I would print out each slide on a piece of paper and place them in order across a large table or counter (Except the teacher center).
By each center, I would have all the supplies the students needed.
Once the small groups of students were done with the centers on the table I would have them come up to the teacher center and we would discuss the questions.
To assess the students I would read their journals and make sure they followed the instructions, watch for participation, and make sure they completed their collage.

12. Teacher Notes Instructions for students:
Welcome to the Math Learning Center for Measuring.
In small groups you will go from center to center.
At each center you will read the instructions and then do as it says. Once you are complete move to the next center.
Once you are complete with all the stations on the counter, as a group go up and meet with your teacher for the last station.
Have fun and don’t forget to bring your learning center journal!
