Workshop: Large Numbers

Find Large Numbers for Local Contexts. The lesson begins with a discussion of large numbers using the context of seating capacity in large stadiums and populations of the cities where they are located. To help students relate to the numbers in the table, find corresponding numbers for your town or city to include in your conversation. For example, find the following data as appropriate:

• number of students in the school
• number of seats in the school auditorium
• number of seats in a local high school football stadium
• population of your city or town
• population of the largest city in your state

Prepare for the Workshop. Review student work and progress from previous lessons to guide instructional decisions about the following expectations:

E1.

Read and write large numbers (to the millions).

E2.

Compare and order large numbers (to the millions).

E3.

Represent large numbers (to the millions) using place value charts, number lines, and number sentences (e.g., 10,705 = 10,000 + 700 + 5.)

E6.

Round quantities to benchmark numbers.

E9.

Estimate sums and differences for large numbers.

In Part 2 of the lesson, students will identify their level of confidence with a particular concept and choose problems from a Workshop Menu. Use your own evaluation of students' progress to help guide their choices.

Plan to organize the class into partners or small groups based on the problems they select. These groups may change as the workshop progresses.

Plan to play Draw, Place, and Read. Plan to have students play the Draw, Place, and Read game in small groups as they finish their workshop tasks. Students should have been introduced to this game in Lesson 4 of this unit. Directions and Place Value Charts are in the Student Activity Book. If students are not familiar with this game, introduce the game after Part 1 of this lesson so students can play independently during the Workshop.
