    Mississippi Grade 3 standards crosswalk

    How each national third grade standard lines up with Mississippi's own standards.

    How to read this

    Each row takes one national third grade standard and shows the Mississippi standard that covers it. Same: the state standard says the same thing. Close: the same skill with small wording differences. Partly: the state covers only part of it in Grade 3. Not in Grade 3: the state has no Grade 3 standard for it (the note says where it sits, when the state says). Third Grade teaches every national standard listed here; the notes tell you what, if anything, to adjust for Mississippi.

    Checked 2026-10-08 against official Mississippi documents. This is an unofficial guide; your state's own documents are the authority.

    3.OA.1Same
    3.OA.A.2

    Interpret whole-number quotients of whole numbers, e.g., interpret 56 ÷ 8 as the number of objects in each share when 56 objects are partitioned equally into 8 shares, or as a number of shares when 56 objects are partitioned into equal shares of 8 objects each. For example, describe a context in which a number of shares or a number of groups can be expressed as 56 ÷ 8.

    3.OA.2Same
    3.OA.A.3

    Use multiplication and division within 100 to solve word problems in situations involving equal groups, arrays, and measurement quantities, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.

    3.OA.3Same
    3.OA.A.4

    Determine the unknown whole number in a multiplication or division equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 × ? = 48, 5 = □ ÷ 3, 6 × 6 = ?.

    Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g., knowing that 8 × 5 = 40, one knows 40 ÷ 5 = 8) or properties of operations. By the end of Grade 3, know from memory all products of two one-digit numbers.

    3.OA.7CloseMississippi adds understanding division when there is no remainder; drops the words "by the end of Grade 3".

    3.MD.C.7.c

    Use tiling to show in a concrete case that the area of a rectangle with whole-number side lengths a and b + c is the sum of a × b and a × c. Use area models to represent the distributive property in mathematical reasoning.

    3.MD.7cSame
    3.MD.C.7.d

    Solve real world and mathematical problems involving perimeters of polygons, including finding the perimeter given the side lengths, finding an unknown side length, and exhibiting rectangles with the same perimeter and different areas or with the same area and different perimeters.

    3.MD.8CloseMississippi adds "(including, but not limited to, modeling, drawing, designing, and creating)" after "exhibiting"; otherwise unchanged.
    3.G.A.1

    Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.

    3.G.1CloseMississippi adds "circles" to the example shapes in the first sentence; the rest is unchanged.

    P.3.6.1, P.3.6.2PartlyGrade 3 compares strengths and directions of forces and plans a force-and-motion experiment (friction, gravity); balanced and unbalanced forces are tested in Grade 5 (P.5.6.4).
    3-PS2-2

    Make observations and/or measurements of an object’s motion to provide evidence that a pattern can be used to predict future motion.

    —Not in Grade 3No Grade 3 objective; Mississippi places predicting future motion from past observation and measurement in Grade 5 (P.5.6.2).
    3-PS2-3

    Ask questions to determine cause and effect relationships of electric or magnetic interactions between two objects not in contact with each other.

    P.3.6.1PartlyCovers magnetic attraction, repulsion and polarity as forces; static electricity is not in the Grade 3 objectives.
    3-PS2-4

    Define a simple design problem that can be solved by applying scientific ideas about magnets.

    P.3.6.3PartlyThe 2026 standards, in force from 2026-27, removed the magnet design objective (old P.3.6.4). Children research and explain everyday uses of magnets; no design task.
    3-LS1-1

    Develop models to describe that organisms have unique and diverse life cycles but all have in common birth, growth, reproduction, and death.

    —Not in Grade 3Not a Grade 3 objective; Mississippi compares life cycles of plants and animals in Grade 4 (L.4.2.1).
    3-LS2-1

    Construct an argument that some animals form groups that help members survive.

    —Not in Grade 3Animals forming groups to survive is not a Mississippi objective in Grade 3 or in any grade from kindergarten to Grade 5.
    3-LS3-1

    Analyze and interpret data to provide evidence that plants and animals have traits inherited from parents and that variation of these traits exists in a group of similar organisms.

    L.3.2.1, L.3.2.3, L.3.2.4CloseSame idea of inherited traits and variation; Mississippi adds how traits pass from one or two parents.
    3-LS3-2

    Use evidence to support the explanation that traits can be influenced by the environment.

    L.3.2.5Same
    3-LS4-1

    Analyze and interpret data from fossils to provide evidence of the organisms and the environments in which they lived long ago.

    L.3.4.5Same
    3-LS4-2

    Use evidence to construct an explanation for how the variations in characteristics among individuals of the same species may provide advantages in surviving, finding mates, and reproducing.

    L.3.4.3Same
    3-LS4-3

    Construct an argument with evidence that in a particular habitat some organisms can survive well, some survive less well, and some cannot survive at all.

    L.3.1.3CloseMississippi asks for examples of features and behaviors that help animals survive in particular environments, rather than an argument about which survive.
    3-LS4-4

    Make a claim about the merit of a solution to a problem caused when the environment changes and the types of plants and animals that live there may change.

    L.3.4.1, L.3.4.2, L.3.4.4CloseChildren design and improve a solution rather than judge one; Mississippi also studies how habitat changes help or harm living things.
    3-ESS2-1

    Represent data in tables and graphical displays to describe typical weather conditions expected during a particular season.

    —Not in Grade 3Not a Grade 3 objective; Mississippi places analyzing weather data in Grade 4 (E.4.9B.1). Grade 3 earth science is rocks, landforms, Earth's systems and resources.
    3-ESS2-2

    Obtain and combine information to describe climates in different regions of the world.

    —Not in Grade 3Not a Grade 3 objective; Mississippi places regional climate differences in Grade 4 (E.4.9B.2).
    3-ESS3-1

    Make a claim about the merit of a design solution that reduces the impacts of a weather-related hazard.

    —Not in Grade 3Not a Grade 3 science objective; reducing the impact of severe weather is Grade 4 (E.4.9C.5). Grade 3 social studies standard 3.G.2 covers natural disasters.
    3-5-ETS1-1

    Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.

    L.3.4.4, E.3.10.4CloseNo separate engineering codes; defining the problem is a step in the two starred Grade 3 objectives that use an engineering design process.
    3-5-ETS1-2

    Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.

    L.3.4.4, E.3.10.4PartlyThe two starred objectives have children design and build a solution; comparing several possible solutions is not stated.
    3-5-ETS1-3

    Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.

    L.3.4.4, E.3.10.4PartlyThe two starred objectives have children evaluate and improve a design; controlled fair tests and failure points are not stated.
