OH.GSS. Geometry and Spatial Sense: Students identify, classify, compare and analyze characteristics, properties and relationships of one-, two- and three-dimensional geometric figures and objects. Students use spatial reasoning, properties of geometric objects, and transformations to analyze mathematical situations and solve problems.
GSS.1. Grade Level Indicator: Characteristics and Properties: Identify and sort two- dimensional shapes and three- dimensional objects. For example:
GSS.1.b. Sort shapes and objects into groups based on student-defined categories.
GSS.1.c. Select all shapes or objects of one type from a group.
OH.M. Measurement: Students estimate and measure to a required degree of accuracy and precision by selecting and using appropriate units, tools and technologies.
M.2. Grade Level Indicator: Use Measurement Techniques and Tools: Compare and order objects of different lengths, areas, weights and capacities; and use relative terms, such as longer, shorter, bigger, smaller, heavier, lighter, more and less.
OH.PFA. Patterns, Functions and Algebra: Students use patterns, relations and functions to model, represent and analyze problem situations that involve variable quantities. Students analyze, model and solve problems using various representations such as tables, graphs and equations.
PFA.1. Grade Level Indicator: Use Patterns, Relations and Functions: Sort, classify and order objects by size, number and other properties. For example:
PFA.1.a. Identify how objects are alike and different.
PFA.1.b. Order three events or objects according to a given attribute, such as time or size.
PFA.1.c. Recognize and explain how objects can be classified in more than one way.
PFA.4. Grade Level Indicator: Use Algebraic Representations: Model a problem situation using physical materials.
PFA.A. Sort, classify and order objects by size, number and other properties, and describe the attributes used.
