• Give each student a printed copy of the original mapped data (with legend) from Step 1: Observation and Discussion along with the Design Tools Guide.
  Note: By now the students should be familiar with both the original map and the design tools.
• Explain: “Remember how we looked at the different mapped data representations and how we used the Design Tools to come up with our own symbols to answer the questions in the Fencepost Activity? Today we are going to discuss mapped data further and practice using these tools ourselves by creating our very own map legends with symbols, colors, marks…”
• First, let’s remind ourselves about our map from earlier in this lesson.
  Invite discussion about the following questions regarding the printed map you have handed out (10 minutes):

What design tools were used to draw the data on this map?
What is included in the legend?
Why do you think they chose this particular design tool for this set of data?
While some tools are better for representing sets of data, there is no right or wrong tool. Are there different design tools we could use to represent this data? Look through the card and discuss what some good choices might be for this topic.

Give each group two additional mapped datasets related to the topic so that each table of three students has a total of three maps to work with. Include the source of the data on each map. Click here for guidance on selecting maps for the exercise. Also, you can visit the Dataset Resources Guide.

A note about map selection for Data Sketches:
–  Select datasets that relate to your topic and tell a story when combined or layered together
–  Begin with data that can be simply drawn or simplified in some way
–  Exclude datasets with confusing legends
–  Try to include a ‘human element’ in at least one of your datasets (for example SOS’s: population density, nighttime lights, human climate niche or shipping routes)

• Invite students to silently observe their maps for a few minutes.
• Ask the students to decide within their group how they might represent the data in each of the three maps in a different way than it is currently while using three distinct design tools (ie. color, symbols, scale) from their Design Tools Guide for the three maps. Have students work on developing new legends for each map using scrap paper, pencils, and markers (10 minutes)
• Ask each student to choose one of the maps. Hand out the Data Sketches Student Worksheet 1 and the Base Map Template.
• Have students paperclip a sheet of tracing paper over the map template and follow the  prompts on Worksheet 1 (please show an example of what they are being asked to do). This worksheet will guide them through beginning their map. You, as the teacher, can walk through each step one at a time, if needed, or have the students follow the instructions independently. Note: The map template provided to be used as a guide under the tracing paper requires each student to create a map that is on the same scale as the others so that these maps can be easily layered together in the second part of this exercise.
  
• “Sketch” – the final task of this worksheet asks for the student to use their new legend as a guide to sketching out their mapped data in a new way. Students are also asked to note important features. Students may begin by tracing the outline of the countries and, although it is not necessary and sometimes time- consuming, it is a way that they can begin to process the map spatially. For that reason, the timing of this component is variable and left up to the teacher. Students should have a minimum of 20 minutes to respond or the teacher may choose to break here and allow the students to complete their mapped “work of art” at home overnight and wrap up the next day with Part 2.
