• Find equivalent representations for the same number
• Use models, explanations, or other representations to represent place value to the thousands place
• Order and compare numbers (ordinal and cardinal)
• Compare whole numbers to landmark numbers (e.g., 100, 250, 500, 1,000)
• Show the relationship between whole numbers
• Compose and decompose (e.g., 34 = 17+17; 34 = 29+5; 34 = 30+4)
• Connect number words and numerals to the quantities they represent

• Represent common fractions, such as halves, thirds, fourths, sixths, and eighths
• Represent a fraction as part of a whole (i.e., fraction of a set, fraction of an area)
• Compare or identify equivalent positive fractional numbers (e.g., a/2, a/3, a/4 where a is a whole number greater than 0 and less than or equal to the denominator)
• Use models, number lines, or explanations

• Represent decimals as part of 100 (within the context of money)

• Develop fluency in adding, subtracting, multiplying and dividing whole numbers
• Develop and use strategies to estimate the results of whole number computations

Patterns, Relationships, and Functions

• Identify specific cases of a variety of patterns both linear and non-numeric, represented in models, tables, words, graphs or sequences by extending the pattern to the next one, two, or three elements, or finding missing elements (geometric and numeric patterns

• Show the equality between two expressions using models or different representations of the expressions or by finding the value that will make an open sentence true (e.g., 2 + _ = 7) using one operation with addition, subtraction or multiplication
• solve mathematical problems to show relationships with equations

• Model problem situations with objects and use graphs, tables, equations to draw conclusions

• Introduce how a change in one variable relates to a change in a second variable
• Identify, describe, and/or compare situations that represent constant rates of change

• Identify, compare, and analyze attributes or properties of angles (i.e., number of angles) or sides (i.e., number of sides or length of sides) of two and three-dimensional shapes
• Develop vocabulary to describe attributes and define classes of shapes such as triangles and pyramids
• Use composition or decomposition of shapes to identify, describe, or distinguish among triangles, squares, rectangles, rhombi, trapezoids, hexagons, or circles demonstrate congruence and similarity of shapes

• Apply coordinate systems to specify locations and to describe paths
• Find location on a coordinate grid using positional words or compass directions interpret and give directions from one location to another using positional words

• Predict and describe the results of sliding, flipping, and turning two-dimensional shapes
• Determine if two-plane figures are congruent by matching
• identify line (mirror) symmetry in two-dimensional models

• Build, compare, copy, and draw geometric objects such as triangles, squares, rectangles, rhombi, trapezoids, hexagons, and circles
• Describe and create mental images of objects, patterns, and paths
• Identify and build models of rectangular prisms from three-dimensional representations
• Use geometric models to solve problems in other areas or disciplines

• Compute perimeter of polygons
• Draw the area of rectangles on grids using a variety of models Express all measures using appropriate units
• Measure length, weight, and volume and select an appropriate type of unit for measuring
• Measure with standard units in the customary system
• Carry out simple unit conversions when solving problems across content strands use units of measures appropriately and consistent

• Estimate perimeters, area, and volumes of irregular shapes (benchmarks: quart to whole quart; kilogram to whole kilogram; gram to whole gram; pound to whole pound)
• Apply appropriate standard units and tools to measure length, area, volume, time, and temperature (benchmarks: hour to 5 minute interval; day; year; 24 hours in 1 day 7 days in 1 week; 365 days in 1 year; C degrees and F degrees to 1 degree)
• Use benchmarks to estimate measurements (benchmarks: inch to ½ inch; foot to whole inch; centimeter to whole centimeter; meter to whole centimeter)
• Use formulas to find the area of a rectangle
• analyze the parts of rectangular solids

• Analyze patterns, trends or distributions in data in a variety of contexts by determining or using most frequent (mode), least frequent, largest, or smallest
• Identify or describe representations or elements of representations that best display a given set of data or situation using line plots, tally charts, tables or bar graphs
• Compare different representations of the same data and evaluate how well each representation shows important aspects of the data

• Make and justify predictions that are based on data
• analyze data to formulate conclusions or to make predictions
