Essential Question: Why are numbers important?
Unit Summary: Students will examine the essential question, “Why are numbers important?” They will work in groups to locate numbers from five books from an assigned section of the library based on the Dewey Decimal System. The groups will find books holding specified number criteria and will fill out a chart to show the numbers they have located. They will use their numbers in number sentences to show greater and less than statements. Then students will discuss the value of numbers and ways they use numbers every day.
Extension Activities
1. Take a field trip walk around the school. Have the students write down all the numbers they
see. Return to class and have them list all they ways numbers are used.
2. Hold a library scavenger hunt. Divide the students into small groups and assign them three
numbers that correspond to the call numbers on books in your library. Have them locate
books with that number and order them from least to greatest.
3. After reading the book, have the students write a short description of the main idea of the book. Use the phrase, “I am a mathematician. I know that _________.”
