Recurring Resources


Print enough copies of the worksheets and handouts so each student has one that aligns with his/her group. Print the Jigsaw Cards. You will need to cut these apart before class. You may want to laminate them first in order to make them last for longer. See instructions on the first slide of the cards for how to prepare cards for classes of different sizes.

If you took down the stations from Activity 5.1, re-set up each of the stations. That is, set up one transportation station with all four transportation cards, one food station with all four food cards, etc.


1. Use the instructional model to show students where they are in the course of the unit.

Show slide 2 of the 5.2 Carbon Emissions Jigsaw PPT.


Circulate the room during both home and expert group discussions to listen to the group conversations. Note if students are drawing on the main points from the handouts or if they have questions.


Encourage students to practice literacy and reading skills during their home groups by reading aloud to each other.

  • Strategically assign groups.

Assign students the reading for homework and discuss as a class the following period.

Extending the Learning

Have students keep a personal log about how they use energy in the four sections discussed in the jigsaw discussion: food, transportation, buildings, and electricity.

Have students do research on how electricity is generated in each of the countries in the Activity. They may be surprised that France produces less carbon than some other countries because they generate a lot of electricity with nuclear power!
