## Glyphs for All Reasons

 Students learn a powerful way to display data, the glyph. Representation, communication, and problem solving are important parts of this lesson.

### Learning Objectives

 Students will: create glyphs interpret glyphs

### Materials

 Crayons Paper plates Class Notes Recording Sheet Glyph Overhead

### Questions for Students

 If you want to know who walks to school, how can you tell from the glyphs the class made? How many students in the class walk to school? Ride the bus? How many is that in all? How many neither walk nor ride the bus? How can you tell? [Students who walk to school will have blueberries on their plates. Students who ride the bus will have blackberries drawn on their plates. Students who neither ride the bus nor walk to school will have a plum drawn.] How many students in our class like mashed potatoes? [Answers will depend upon the students' responses. Count up the number of plates with potatoes drawn on them.] How many students in our class have brothers? Have sisters? Have no brothers or sisters? How could you tell that from looking at the glyphs? Does anyone have two brothers? Three sisters? [Answers will depend upon the students' responses. The number of green peas drawn indicates the number of brothers a student has. The number of sticks of celery indicates the number of sisters a student has.] Could you find out from the glyph how old someone is? How? [Yes, you can find out someone's age by looking at the number of radishes drawn.] Suppose I want to find out how many students brought their lunch today. How would I do that by looking at the glyph? [You would count the number of plates which have carrots drawn on them.] How many students have a birthday this month? Can I tell how many students have a birthday in [name another month]? [The number of students with birthdays this month will depend upon student responses. Simply count the number of plates with a blue rim. No, you cannot tell how many students have a birthday in another month.] How would you help a friend read your glyph? [Student responses will vary. Some students may suggest creating a key, similar to a pictograph, to indicate what each picture represents.]

### Assessment Options

 At this stage of the unit, it is important to know whether students can do the following: Create and read a glyph. Record student observations on the Class Notes Recording Sheet. Ask students, "Is your food diary chart up-to-date?"

### Extensions

 The glyph is such a versatile data representation tool that you will wish to have students make glyphs several times during the year. It is especially appropriate as a "getting to know you" activity during the first week of school. It is also an innovative way to review social studies data. For example, suppose you have just studied regions in your state or the characteristics of your community or of several states. A glyph that could be used in the latter case might be: Pick a state. [You might assign states to students.] On your paper, draw the outline of your state. If it was one of the original colonies, draw the outline in blue. If not, draw it in red. Draw a green star where the capitol is, and write the capitol's name there. Draw any large rivers in blue. Draw any mountains in brown. If your state is on the seacoast, draw some waves where the coast is. Draw a red star where you live. Draw a picture of one important crop.

### Teacher Reflection

 Which students could easily classify data about themselves and draw the appropriate indicator on the glyph? Which students could gather data by looking at another student's glyph? Are any students still having difficulty with the objectives of this lesson? What additional instructional experiences do they need? What will I do differently the next time that I teach this lesson?
