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.a. Identify and describe two-dimensional figures and three-dimensional objects from the environment using the child’s own vocabulary.
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.
GSS.2. Grade Level Indicator: Spatial Relationships: Name and demonstrate the relative position of objects as follows:
GSS.2.a. Place objects over, under, inside, outside, on, beside, between, above, below, on top of, upside-down, behind, in back of, in front of.
GSS.2.b. Describe placement of objects with terms, such as on, inside, outside, above, below, over, under, beside, between, in front of, behind.
GSS.A. Describe and create plane figures: circle, rectangle, square, triangle, hexagon, trapezoid, parallelogram and rhombus, and identify them in the environment.
GSS.C. Sort and compare two-dimensional figures and three-dimensional objects according to their characteristics and properties.
GSS.E. Recognize two- and three-dimensional objects from different positions.
GSS.F. Describe location, using comparative (before, after), directional (above, below), and positional (first, last) words.
GSS.G. Identify and draw figures with line symmetry.
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.MP. Mathematical Processes: Students use mathematical processes and knowledge to solve problems. Students apply problem-solving and decision-making techniques, and communicate mathematical ideas.
MP.G. Use invented and conventional symbols and common language to describe a problem situation and solution.
OH.NNSO. Number, Number Sense and Operations: Students demonstrate number sense, including an understanding of number systems and operations and how they relate to one another. Students compute fluently and make reasonable estimates using paper and pencil, technology-supported and mental methods.
NNSO.1. Grade Level Indicator: Number and Number Systems: Compare and order whole numbers up to 10.
NNSO.10. Grade Level Indicator: Meaning of Operations: Model and represent addition as combining sets and counting on, and subtraction as take-away and comparison. For example:
NNSO.10.a. Combine and separate small sets of objects in contextual situations; e.g., add or subtract one, two, or another small amount.
NNSO.10.b. Count on (forward) and count back (backward) on a number line between 0 and 10.
NNSO.2. Grade Level Indicator: Number and Number Systems: Explain rules of counting, such as each object should be counted once and that order does not change the number.
NNSO.3. Grade Level Indicator: Number and Number Systems: Count to twenty; e.g., in play situations or while reading number books.
NNSO.4. Grade Level Indicator: Number and Number Systems: Determine 'how many' in sets (groups) of 10 or fewer objects.
NNSO.6. Grade Level Indicator: Number and Number Systems: Construct multiple sets of objects each containing the same number of objects.
NNSO.8. Grade Level Indicator: Number and Number Systems: Represent and use whole numbers in flexible ways, including relating, composing and decomposing numbers; e.g., 5 marbles can be 2 red and 3 green or 1 red and 4 green.
NNSO.9. Grade Level Indicator: Number and Number Systems: Identify and state the value of a penny, nickel and dime.
NNSO.A. Use place value concepts to represent whole numbers using numerals, words and physical models.
NNSO.B. Recognize, classify, compare and order whole numbers.
NNSO.C. Represent commonly used fractions using words and physical models.
NNSO.D. Determine the value of a collection of coins and dollar bills.
NNSO.F. Count, using numerals and ordinal numbers.
NNSO.G. Model, represent and explain addition as combining sets and counting on.
NNSO.H. Model, represent and explain subtraction as comparison, take-away and part-to-whole.
NNSO.K. Demonstrate fluency in addition facts with addends through 9 and corresponding subtractions.
NNSO.L. Demonstrate fluency in adding and subtracting multiples of 10, and recognize combinations that make 10.
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.2. Grade Level Indicator: Use Patterns, Relations and Functions: Identify, create, extend and copy sequences of sounds (such as musical notes), shapes (such as buttons, leaves or blocks), motions (such as hops or skips), and numbers from 1 to 10.
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.
PFA.B. Extend sequences of sounds and shapes or simple number patterns, and create and record similar patterns.
PFA.D. Model problem situations, using objects, pictures, numbers and other symbols.
