Clarification ~ VSC 2.A.1.a ~ Mathematics Grade PK ~ School Improvement in Maryland

Clarifications: Each clarification provides an explanation of the indicator/objective to help teachers better understand the concept. Classroom examples are often included to further illustrate the concept. While classroom examples could be shared with the students, the intended audience for the explanation/clarification is the classroom teacher-not the student. In addition, classroom examples may or may not reflect the assessment limits.

Standard 2.0 Knowledge of Geometry

Topic A. Plane Geometric Figures

Indicator 1. Recognize and use the attributes of plane geometric figures

Objective a. Sort objects by one attribute such as: shape, color, and size

Clarification
Before children are ready to sort, they must first be able to identify attributes, match, and compare objects. The first attribute young children notice is color. Then they begin to notice the shape and size of an object. The attribute of size is more difficult for students. Provide opportunities for students to sort throughout the school year as these activities help them become flexible thinkers. Sorting experiences build the foundation for every area in mathematics: Algebra - In order to name a pattern, a student must be able to identify similarities and differences. Statistics - Sorting prepares students for organizing and analyzing data. Measurement - The attribute of size is noticed when students create sorting groups. Geometry - In creating sorts, students also use the attribute of shape to make groups. Number Concept - Sorting is a natural connection to number concepts because students count to identify the number in each group and to compare these groups. It is important that students describe the groups in a sort. This encourages them to reflect on the objects sorted and engage in reflective discussion. These discussions naturally introduce the language of mathematics with words such as more, few, many, most, and least to describe collections.
