Lesson 6

Ten Times as Many

Lesson Purpose

The purpose of this lesson is for students to represent and solve multiplicative comparison problems involving multiples of 10.

Lesson Narrative

In this lesson, students apply place value understanding, where they look for and make use of structure, to what they have learned about representing and solving multiplicative comparison problems (MP7). They use tape diagrams and equations to represent multiplicative comparisons that are “10 times as many”. 

Students will build on this understanding in the next section as they convert measurements from larger metric units into smaller ones (for instance, from meters to centimeters, kilograms to grams, or liters to milliliters).

Teacher Reflection Questions

In today’s lesson, students considered multiplication with products greater than 100. What vocabulary did you hear students using that indicated a use of place value and beginning understanding of multiplication of multi-digit numbers?

Suggested Centers

  • How Close? (1–5), Stage 6: Multiply to 3,000 (Addressing)
  • Compare (1–5), Stage 3: Multiply within 100 (Supporting)
