2nd year in a row doing this lesson with 5th Grade. Students learn about Chuck Close, the grid method, and breaking big jobs into small pieces and sharing in the workload to accomplish big things. Last year my 5th graders created two large portraits of our Principle and Vice Principle. This year 5th graders created portraits two other administrators at our school. These portraits are 32"x 40". Students do not know who they are creating portraits of as they are doing it. I keep it a secret. An 8x10 photo is cut into one inch pieces and spread out among 4 classes of 5th graders. Students enlarge their piece of the portrait to 4"x4" using a grid, then complete it with pencil value. Students do the initial layout and piecing/taping together of the squares. I come back when they are done and straighten up some of their seems. It is a lot of fun to watch the students guess who the portrait is of as it comes together. The whole lesson takes about 3 class times (50 minutes each)to teach and complete. After these are done, we give them to the subject of the portrait as a gift.
Students use a grid with the numbers of the pieces written on it as a map while they put the portrait pieces together.
Students lay their one inch square on top of their value drawn piece for comparison.
Sometimes a few pieces get lost, but special helpers get picked to do the missing pieces. Everyone enjoys this project.
