Synopsis
In this activity, students engage with reading, writing, and comparing numbers to better understand the effects of human activity on the world’s organisms. Each section of the 1,000 Number Packet highlights a different species whose habitat has been impacted by climate change.
Accompanying Teaching Materials
Teaching Tips
• Review the background information and directions with students as a whole group. Then, let students work independently on the 1,000 Number Packet. The Comparing Numbers section can be completed in partners or independently.
• See the lesson Using Numbers to Think About Biodiversity (Number Sense and Biodiversity #2) for differentiated options, 100 Number Packet and 20 Number Packet (teacher-led).
• It is important to note that the concept of endangered animals may be difficult for some students. Be sure to check in and provide a safe space for students to share their feelings related to this topic.
• This resource is a great addition to a unit on understanding numbers in base ten.
• To extend learning, students may research other organisms on the IUCN Red List in their region.
Scientist Notes

Students can use numbers to investigate and tally species that are listed on the IUCN Red List. It is imperative that they are able to identify and correlate the pace of biodiversity loss with changes in the environment. Every supplementary resource included in the activity guide has been thoroughly researched and approved by our scientific review team.
