After a few minutes carefully take the envelope away from the stamp. Put the stamp between two sheets of blotting paper to dry and place a light weight on top. Always handle the stamp carefully with tweasers. School Discuss the meaning of classification. Challenge each group to come up with at least three different classifications for the stamps provided.
Groups present their stamps to the class who try to guess what classification system was used.
Each pupil chooses one stamp, examines it carefully, and prepares a short oral description to deliver to the group or the class. After the description has been delivered, have all pupils roughly sketch the stamp according to the description given. Compare the sketches with the stamp. Pupils evaluate this by giving their own oral description of a stamp. Can they suggest improvements to increase accuracy of the descriptions.
