Topics: Two and Three dimensional shapes, measurement
proportions
Grade level: Third
Objective: After reading the book Flat Stanley the
students will be able to determine the difference between two
dimensional and three dimensional shapes.
Materials: Flat Stanley by Jeff Brown New York: Harper
& Row, 1964
toothpicks, gummy candy, marshmallows, pieces of clay, starburst
candy, construction paper, scissors, various two and three dimensional
shapes
Book Review: An enormous bulletin board falls on Stanley
Lamchop and squashes him flat as a pancake. Stanley is now 4'
tall, about 1'wide, and ½ " thick. The story tells
how Stanley;s life changes because of his new proportions, and
his adventures while his brother, Arthur, figures out how to return
Stanley to his former proportions.
Activity:
Introduction: In small groups have the students construct a
paper model of Stanley using the measurements given in the story.
- Have the students determine other things that are ½ inch
thick and list them on the board.
- Discuss the idea of being only ½ inch thick and have
students decide if Stanley could really stand by himself using
the dimensions given in the book.
- Then proceed to discuss how Stanley changed throughout the
book. Introduce the concepts of two and three dimensional shapes
using numerous objects as manipulatives. Have students brainstorm
lists of these two types.
- Once students grasp the two concepts, have the students make
edible models of three dimensional models using the candy listed.
The students can share their models and then eat them when they
are finished.
Extension Activities: The students can create their own
"Stanley story" and make a model of their character
using their dimensions.
