In this lesson, students use a base number to compare the numbers of extinct, endangered, and vulnerable species and consider how to help protect animals and plants.

 

Step 1 - Inquire: Students estimate the number of living things in a group to get a sense of the large number of species in the world.

Step 2 - Investigate: Students write numbers to represent the number of living things on the IUCN's Red List.

Step 3 - Inspire: Students compare and contrast numbers to compare groups of living things, reflecting on how to help living things in their community.
