Prior to this point, students have learned to compare and order large numbers. They have also read, written, and decomposed numbers in terms of place value. In this lesson, students look at the relationship between multi-digit numbers and multiples of 1,000, 10,000, and 100,000. Number lines are the central representation of this lesson. They allow students to reason visually before they transition to reasoning numerically when they round numbers in future lessons.
- Identify the closest multiples of 1,000, 10,000, and 100,000 to a given whole number.
- Let’s explore multiples of 1,000, 10,000, and 100,000 and how other numbers relate to them.
- Create number lines from the blackline master and post them around the room before the activity.
