This lesson is for students learning geometry. I begin the geometry unit reading The Greedy Triangle. After reading the book, I give the student a worksheet referencing the book that was read aloud. We go over the worksheet together. As we go through our geometry lessons and learn vocabulary, the students come up to the front and "model" or "pose" for the term. Then a picture is taken with a digital camera.

Vocabulary:
acute angle- student holds arms out to the side
(Def- angle Less than 90 degrees a "cute" angle)
Obtuse angle - student holds arms out to the side
(Def- angle Greater than 90 degrees less than
180 degrees)
Right angle- student holds arm straight up by their ear
and one arm out to the side(Def-90 degree angle)

Ray- student holds one hand out to the side with a fist
(vertex/point) and the other hand out to the side

both directions

line segment- student holds out both hands to the sides

flip - a student stands facing forward in a fancy pose and
takes one picture - then take a picture with the same
student with their back facing the camera to show the
flip. Def- an object moving from front to back along
the same plane

Slide- student faces the camera in a pose taking one
picture then moves to the left or right still facing
the camera. Def- an object that moves from left to
right along the same plane

Rotate- student stands and take one picture, 2nd picture

Definitions provided may be adjusted to the grade level. Vocabulary terms may be added to make the book longer or to fit your classroom needs.

After the definitions have been discussed, you have taken pictures, and written the definitions it is time to put the book together. Give the students time to write all of their geometry definitions in awesome (grade level) sentences. Then have time where everyone can share their outstanding sentences. Do a silent vote to choose a sentence for each vocabulary term to be added to the book.
