"Challenge the code reading ability of your students. 

Students develop a face diagram using symbols. 

From hair color to birthdays, students share a little about themselves with their classmates. 

After all the bioglyphs have been completed, display them and challenge your students to identify their classmates. 

Students may ask questions that require yes or no answers only! 

"Is this your bioglyph?" is not an acceptable question! 

After ten minutes, have each student write their name on their picture and allow time for them to check their answers."
