The purpose of this lesson is for students to represent numbers using base-ten blocks, base-ten diagrams, expanded form, numerals, and word form.
Prior to this grade, students represented numbers within 1,000 using number names, base-ten blocks and diagrams, and expanded form. They used place value to compose and decompose numbers within 1,000.
In this lesson, students revisit these familiar representations and ways of reasoning about numbers as they work to build fluency with addition and subtraction within 1,000. The base-ten diagrams and the expanded form will continue to be used to support students throughout this unit. Give students access to base-ten blocks, in case requested.
- Represent numbers to 1,000 in different ways using place value understanding.
- Representemos números de distintas maneras.
