# Lesson 6

¿Cuánto es 10,000?

### Lesson Purpose

### Lesson Narrative

In this lesson, students build on their understanding of the base-ten structure to develop a sense of the magnitude of 10,000. They first use base-ten blocks and base-ten diagrams to build four-digit and five-digit numbers. They then use a 10-by-10 grid to represent 100 and work together to build a representation of 1,000, and then 10,000. Students may notice the inherent multiplicative structure of the 10-by-10 grids or the array of 10,000 and use counting strategies to identify significant groups of 10 (for example, 10 groups of 100 and 10 groups of 1,000).

Activity 2: ¿Qué es 10,000?

### Learning Goals

Teacher Facing

- Develop a sense of the relative magnitude of 10,000.
- Recognize ten-thousand as 10 groups of 1,000.

### Student Facing

- Representemos 10,000.

### Required Materials

Materials to Gather

Materials to Copy

- Build Numbers (1-5 Digit Cards)
- 10-by-10 Square Grids

### Required Preparation

Activity 1:

- Create a set of cards from the blackline master for each group of 4. Remove the cards showing 1. These cards will be redistributed during the activity.
- Each group of 4 needs a small collection of base-ten blocks (for instance: 2 thousands, 5 hundreds, 10 tens, and 20 ones).
