Unit 4, Lesson 14
Multiples of 10,000 and 100,000
Grade 4
Preparation
Lesson Narrative
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. Number lines allow students to reason visually before they reason numerically to round numbers in future lessons.
- Engagement
- MLR8
- Use a number line diagram to identify (orally and in writing) 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.
Required Materials
Activity 1
Required Preparation
- Create number lines from the blackline master and post them around the room before the activity.
Teacher Reflection Questions
Who participated in math class today? What assumptions are you making about those who did not participate? How can you leverage each of your student’s ideas to support them in being seen and heard in tomorrow’s math class?
