Lesson 14

Múltiplos de 10,000 y de 100,000

Lesson Purpose

The purpose of this lesson is for students to reason about the position of numbers relative to their multiples of 1,000, 10,000, and 100,000.

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. They allow students to reason visually before they transition to reasoning numerically when they round numbers in future lessons.
