Key Ideas and Details

• Answer questions (who, what, where, when, why, how) to show understanding of key text details.

Geometry

• Recognize and draw shapes with specific attributes (e.g., angles, faces).
• Identify triangles, quadrilaterals, pentagons, hexagons, and cubes.
• Divide circles and rectangles into two, three, or four equal shares and describe them using terms like halves, thirds, and fourths.
• Recognize equal shares don't need to have the same shape.
• Shapes in different categories (rhombuses, rectangles, etc.) share attributes, defining larger categories (quadrilaterals).
• Recognize/draw rhombuses, rectangles, squares as quadrilaterals.
• Partition shapes into equal areas, expressing each part's area as a unit fraction.

• Measure how much longer one object is than another, expressing the length difference in standard units.
• Represent whole number lengths on a number line diagram and represent whole-number sums and differences within 100.
• Tell and write time to the nearest minute; measure time intervals in minutes, solve word problems involving addition and subtraction of time intervals using number line diagrams.

Measurement, Data, and Probability

• Measure/estimate liquid volumes and masses using grams, kilograms, and liters.
• Solve one-step word problems involving masses or volumes in the same units.
• Draw picture and bar graphs (single-unit scale) to represent data sets (up to four categories).
• Solve put-together, take-apart, and comparison problems using graph data.
• Draw scaled picture and bar graphs with several categories.
• Solve one- and two-step "how many more" and "how many less" problems from scaled bar graphs.
• Generate measurement data by measuring lengths with rulers marked in halves and fourths of an inch, presenting data as a line plot.
• Measure areas by counting unit squares (cm², m², in², ft², improvised units).
• Solve real-world perimeter problems, including finding perimeter given side lengths or an unknown side length.
• Exhibit rectangles with the same perimeter and different areas or the same area and different perimeters.
• Use addition and subtraction within 100 to solve one- and two-step word problems with unknowns in all positions, using drawings and equations.
• Fluently add and subtract within 20 using mental strategies.
• Interpret products of whole numbers, e.g., 5 x 7 as the total number of objects in 5 groups of 7.

Algebraic Concepts

• Interpret whole-number quotients, e.g., 56 ÷ 8 as the number of objects in each share when 56 objects are split equally into 8 shares.
• Use multiplication/division within 100 to solve word problems involving equal groups, arrays, and measurement quantities.
• Use drawings/equations with a symbol to represent the unknown number.
• Determine the unknown whole number in a multiplication or division relating three whole numbers.
• Apply properties of operations as strategies.
• Division as an unknown-factor problem.
• Fluently multiply/divide within 100 using strategies like the relationship between multiplication/division or properties of operations.
• Solve two-step word problems with four operations; represent problems using equations with a letter for the unknown quantity and assess reasonableness.
• Identify arithmetic patterns (addition/multiplication tables) and strategies.
• Understand three-digit numbers represent amounts of hundreds, tens, and ones.
• Count within 1000; skip-count by 5s, 10s, and 100s.
• Read/write numbers to 1000 using base-ten numerals, number names, and expanded form.
• Compare three-digit numbers based on hundreds, tens, and ones digits, using >, =, < to record comparisons.

Numbers and Operations

• Add/subtract within 1000 using concrete models, drawings, place value strategies, properties of operations, and/or the relationship between addition and subtraction; relate to a written method.
• Add/subtract hundreds, tens, and ones (sometimes it is necessary to compose or decompose tens or hundreds).
• Mentally add/subtract 10 or 100 to/from numbers between 100–900.
• Use place value understanding to round whole numbers to the nearest 10 or 100.
• Fluently add/subtract within 1000 using strategies/algorithms based on place value, properties of operations, and/or the addition/subtraction relationship.
• Multiply one-digit numbers by multiples of 10 in the range 10–90, using place value/properties.
• Understand a fraction 1/b as one part of a whole divided into b equal parts: understand a fraction a/b as the quantity formed by a parts of size 1/b.
• Understand a fraction as a number on the number line: represent fractions on a number line diagram.
• Explain fraction equivalence in special cases and compare fractions by reasoning about their size.

Standard English and Purposes

• Write opinion pieces on topics/texts, supporting a point of view with reasons.
