Numbers: Numbers are symbolic representations that help us see and describe attributes.
I. Making Sense of Attributes
During this unit students use logical thinking to apply rules based on observable and measurable attributes to create a framework for organizing and understanding the world around them. Looking at a group of objects, students will make comparisons by describing similarities and differences. Classifying objects is done using a variety of attributes. Counting is one strategy used when sorting by attributes. Identifying 2D and 3D shapes is a strategy used when sorting by attributes.
II. Composition and Decomposition
During this unit students will compose and decompose numbers, sets, and shapes , and communicate precisely about measurement. Students will use non standard units to compare weight and length. Students will add to measure and compare to subtract. Students will unitize groups of ten and use ten and some more to describe teen numbers. A number can be represented by putting together parts of the number or breaking apart the number in different ways. There is more than one way to solve addition and subtraction problems. We use shapes to understand the composition of the real world. Shapes can be decomposed into its parts and new shapes can be made by putting together existing shapes.
