# Model and represent a number in different ways by using place value concepts

Big Ideas: Numbers can be decomposed into smaller parts and then composed to recreate that number. Numbers can be modeled in more than one way by composing the parts in different ways. This lesson continues to develop students' understanding of the structure of the base ten system. This task explores how numbers can be modeled and represented in different ways. In this task, students will decompose a number into multiples of ten to help Post Officer Peg in packaging the mail. The work in this task will help students build a strong foundation in understanding the base ten system that will foster understanding multiplication and division and in working with decimals. Vocabulary: decompose, compose, model Special Materials: base ten blocks (optional)
