Unit 3, Lesson 34# Multiply two-digit multiples of 10 by two-digit numbers using a place value chart

EngageNY 60 min(s)

In this lesson, students discover that a two-digit multiple of 10 times another two-digit number is the same as 10 times n-whole number times another two-digit number, e.g., 30 x 14 = 3 x 10 x 14. Then, students use the place value chart to develop their understanding of how to multiply a two-digit multiple of 10 times another two-digit number.
