About This Lesson
This unit of lessons was designed to suggest methods of teaching regrouping without the traditional algorithm of “carrying”. They allow young students to compose a ten from ten ones and to understand and be able to explain how place value is changed when a two-digit and a one-digit number are added. Collaborative learning and the use of manipulatives are included in each lesson. The overarching objective of this unit is to further develop students’ understanding of numbers and their relationship to other numbers. Aligned to Common Core State Standard: 1.NBT.4
