This packet contains a variety of activities and tasks that aligns with Common Core's progression of decimals. These activities follow the concrete, representational, abstract format of conceptually understanding the development of decimals. This progression is base on the following standards: 4.NF.6, 4.NF.7, 5.NBT.1, 5.NBT.3, 5.NBT.4, 5.NBT.7, and 6.NS.3, which in turn leads to algebra and beyond.
