Grado 4
Preparation
Lesson Narrative
This lesson shifts the focus from reading and writing numbers to describing the multiplicative relationship between place values in a multi-digit number. In previous lessons, students used base-ten blocks to represent large numbers, and wrote numbers in expanded form. In this lesson, students use their developing understanding of the value of a digit to begin to articulate that a digit in one place is ten times the value as the same digit in a place to its right.
The syntheses in this lesson help students connect the language of “ten times the value” to equations to help them represent this concept.
