4.MN&O Number and Operations

4.MN&O-4-1 Demonstrates conceptual understanding of rational numbers with respect to:
4.MN&O-4-1.1 whole numbers from 0 to 999,999 through equivalency, composition, decomposition, or place value using models, explanations, or other representations; and
4.MN&O-4-1.2 positive fractional numbers (benchmark fractions: a/2, a/3, a/4, a/5, a/6, a/8, or a/10, where a is a whole number greater than 0 and less than or equal to the denominator) as a part to whole relationship in area, set, or linear models where the number of parts in the whole are equal to, and a multiple or factor of the denominator; and decimals as hundredths within the context of money, or tenths within the context of metric measurements (e.g., 2.3 cm) using models, explanations, or other representations.
4.MN&O-4-2 Demonstrates understanding of the relative magnitude of numbers from 0 to 999,999 by ordering or comparing whole numbers; and ordering, comparing, or identifying equivalent proper positive fractional numbers; or decimals using models, number lines, or explanations.
4.MN&O-4-3 Demonstrates conceptual understanding of mathematical operations by describing or illustrating the relationship between repeated subtraction and division (no remainders); the inverse relationship between multiplication and division of whole numbers; or the addition or subtraction of positive fractional numbers with like denominators using models, number lines, or explanations.
4.MN&O-4-4 Accurately solves problems involving multiple operations on whole numbers or the use of the properties of factors and multiples; and addition or subtraction of decimals and positive proper fractions with like denominators. (Multiplication limited to 2 digits by 2 digits, and division limited to 1 digit divisors.)

4.MG&M Geometry and Measurement

4.MG&M-4-1 Uses properties or attributes of angles (number of angles) or sides (number of sides, length of sides, parallelism, or perpendicularity) to identify, describe, or distinguish among triangles, squares, rectangles, rhombi, trapezoids, hexagons, or octagons; or classify angles relative to 90° as more than, less than, or equal to.
4.MG&M-4-3 Uses properties or attributes (shape of bases or number of lateral faces) to identify, compare, or describe three-dimensional shapes (rectangular prisms, triangular prisms, cylinders, or spheres).
- Geometry: Identify planar and solid figures (Fourth grade - P.1)
- Geometry: Which 3-dimensional figure is being described? (Fourth grade - P.5)
4.MG&M-4-4 Demonstrates conceptual understanding of congruency by matching congruent figures using reflections, translations, or rotations (flips, slides, or turns), or as the result of composing or decomposing shapes using models or explanations.
- Geometry: Reflection, rotation, and translation (Third grade - P.5)
- Geometry: Similar and congruent (Fourth grade - P.8)
4.MG&M-4-5 Demonstrates conceptual understanding of similarity by applying scales on maps, or applying characteristics of similar figures (same shape but not necessarily the same size) to identify similar figures, or to solve problems involving similar figures. Describes relationships using models or sc explanations.
- Geometry: Similar and congruent (Fourth grade - P.8)
4.MG&M-4-6 Demonstrates conceptual understanding of perimeter of polygons, and the area of rectangles, polygons or irregular shapes on grids using a variety of models, manipulatives, or formulas. Expresses all measures using appropriate units.
4.MG&M-4-7 Measures and uses units of measures appropriately and consistently, and makes conversions within systems when solving problems across the content strands.

4.MF&A Functions and Algebra

4.MF&A-4-1 Identifies and extends to specific cases a variety of patterns (linear and nonlinear) represented in models, tables or sequences; and writes a rule in words or sc symbols to find the next case.
4.MF&A-4-3 Demonstrates conceptual understanding of algebraic expressions by using letters or symbols to represent unknown quantities to write simple linear algebraic expressions involving any one of the four operations; or by evaluating simple linear algebraic expressions using whole numbers.
4.MF&A-4-4 Demonstrates conceptual understanding of equality by showing equivalence between two expressions using models or different representations of the expressions, by simplifying numerical expressions where left to right computations may be modified only by the use of parentheses [e.g., 14 - (2 x 5)] (expressions consistent with the parameters of M(F&A)-4-3), and by solving one-step linear equations of the form ax = c, x ± b = c, where a, b, and c are whole numbers with a "not equal to" 0.

4.MDSP Data, Statistics, and Probability

4.MDSP-4-1 Interprets a given representation (line plots, tables, bar graphs, pictographs, or circle graphs) to answer questions related to the data, to analyze the data to formulate or justify conclusions, to make predictions, or to solve problems.
4.MDSP-4-2 Analyzes patterns, trends, or distributions in data in a variety of contexts by determining or using measures of central tendency (median or mode), or range.
- Probability and statistics: Mean, median, mode, and range (Fourth grade - U.3)
- Probability and statistics: Interpret charts to find mean, median, mode, and range (Fourth grade - U.4)
4.MDSP-4-4 Uses counting techniques to solve problems in context involving combinations or simple permutations (e.g., Given a map - Determine the number of paths from point A to point B.) using a variety of strategies (e.g., organized lists, tables, tree diagrams, or sc others).
- Probability and statistics: Combinations (Fourth grade - U.5)
4.MDSP-4-5 For a probability event in which the sample space may or may not contain equally likely outcomes, determines the theoretical probability of an event and expresses the result as part to whole (e.g., two out of five).
- Probability and statistics: Calculate probability (Fourth grade - U.1)
