Chapter 1 (Sept)
Chapter 1 Place Value of Whole Numbers: Chapter 1 is a critical chapter. The chapter focuses on quantities to 100,000, but CCSS expects understanding to 1,000,000, which can be added. Note that students are expected to be proficient renaming numbers (1200 is 12 hundreds or 120 tens). Students use place value chips instead of base ten proportional materials. These are more abstract. Expanded notation and comparing are emphasied with the place value models and chats.d
