    Wyoming standards

    Math

    2023 Mathematics (Emended Feb. 2025) Wyoming Content and Performance Standards

    Based on Common Core · adopted 2023

    In effect since July 2024, with full use from 2025-26. Grade 3 keeps Common Core codes without the cluster letter (for example 3.NF.2a) but lists only 20 codes: multiplication and division facts, two-step problems, adding and subtracting within 1,000, fractions, line plots, area and quadrilaterals. Third Grade covers these and also teaches rounding, time, graphs and perimeter, which Wyoming does not list for Grade 3.

    Official standards

    English Language Arts

    2012 Wyoming English Language Arts Content and Performance Standards

    Common Core · adopted 2012

    Wyoming's current ELA standards are the Common Core standards with the same codes (for example RF.3.3.a). The state's rules, effective July 2025, still name the 2012 standards, and they are the only ELA set on the state's standards page. New ELA standards proposed in 2025 were listed as in progress when we checked; we could not confirm whether they have been adopted since.

    Official standards

    Science

    2023 Science (Emended Feb. 2025) Wyoming Content and Performance Standards

    Based on the national science framework · adopted 2023

    In effect since July 2024, with full use from the 2025-26 school year. Grade 3 lists five expectations that use the national codes (for example 3-PS2-3): magnets and electric forces, inherited traits, environmental change, weather hazards and defining a design problem. Comparing design solutions is listed in Grade 4 and fair tests in Grade 5. Third Grade covers the five and teaches more.

    Official standards

    Social Studies

    2014 Wyoming Social Studies Content and Performance Standards with 2018 Additions

    State's own standards

    Adopted in 2014 with additions in 2018. Benchmarks are set for the end of Grade 5 and carry codes such as SS5.1.5.a, so Grades 3 to 5 share them and local schools decide the order. The 2018 additions cover the Eastern Shoshone and Northern Arapaho. Proposed 2026 standards were out for public input until September 27, 2026 and are not yet adopted.

    Grade 3 differences

    1. In Wyoming

      Math: in two-step word problems children apply the order of operations when there are no parentheses, and the problems use whole numbers only (3.OA.8, with parts 3.OA.8a and 3.OA.8b).

      Suggested swap in Third Grade

      Math Week 15 (two-step problems): add a day of problems written without parentheses, such as 4 + 3 x 5, and teach multiplying or dividing before adding or subtracting.

    2. In Wyoming

      Social studies (by the end of Grade 5): children understand that the Northern Arapaho and Eastern Shoshone are sovereign nations with their own systems of governance (SS5.1.5.a), that tribal governments have separate legal systems (SS5.1.4), and the basic origins of the United States Constitution, such as the Declaration of Independence (SS5.1.3).

      Suggested swap in Third Grade

      Social Studies Week 20 (three branches): add a lesson on the Eastern Shoshone and Northern Arapaho as nations that govern themselves, and one on how the Declaration of Independence led to the Constitution; Week 19 (local government): mention tribal courts and laws.

    3. In Wyoming

      Social studies (by the end of Grade 5): children identify the boundaries of the Wind River Indian Reservation (SS5.5.1.a) and place names connected to the Indigenous Tribes of Wyoming (SS5.5.3.a.ii), and describe why sacred sites such as Devils Tower/Bear Lodge and the Bighorn Medicine Wheel matter to the tribes (SS5.5.3.a.i).

      Suggested swap in Third Grade

      Social Studies Week 3 (maps and globes): outline the Wind River Indian Reservation on a Wyoming map and mark Devils Tower/Bear Lodge and the Bighorn Medicine Wheel; Week 10 (U.S. geography): find three Wyoming place names that come from the tribes and read why the two sites are sacred.

    4. In Wyoming

      Social studies (by the end of Grade 5): children describe the characteristics and contributions of local and state cultural groups, including the Indigenous Tribes of Wyoming (SS5.2.3), positive and negative interactions among cultural groups and important individuals such as Chief Washakie and Sacagawea (SS5.2.4), and how the environment shaped the way the tribes lived (SS5.5.4.a).

      Suggested swap in Third Grade

      Social Studies Weeks 6 and 12 (Native peoples; Native nations across regions): focus on the Eastern Shoshone and Northern Arapaho, their contributions and how the land shaped their way of life; Week 7 (explorers and settlers): read about Chief Washakie and Sacagawea and how tribes and newcomers got along or clashed.

    5. In Wyoming

      Social studies (by the end of Grade 5): children explain how small changes lead to big changes in history (SS5.4.1), how tools and technology change over time (SS5.4.2), and, using cause and effect, how current events affect people, including the Indigenous Tribes of Wyoming (SS5.4.3).

      Suggested swap in Third Grade

      Social Studies Week 8 (how our community began): chart one small change that led to a big one in Wyoming, such as horses reaching the Plains tribes or the Homestead Act, and show how one tool changed over time; Weeks 33-34 (civic action): pick one current event and explain who it affects and why.

    6. In Wyoming

      Social studies (by the end of Grade 5): children use media resources to answer a question, judge whether information is accurate and relevant, and use digital tools to research and present (SS5.6.1, SS5.6.2, SS5.6.3). They also tell primary sources from secondary sources and summarize both kinds about a historical event (SS5.6.4, SS5.4.5).

      Suggested swap in Third Grade

      ELA Week 17 (research basics): check each source for accuracy and relevance; Social Studies Week 8 (how our community began): compare a primary source, such as an old photograph or letter, with a secondary source on the same event; Week 35 (community project): research and present with a digital tool.

    7. In Wyoming

      Social studies (by the end of Grade 5): children describe how the environment influences people in Wyoming and how people adjust to or change it (SS5.5.4).

      Suggested swap in Third Grade

      Social Studies Week 4 (landforms, water and resources): add how Wyoming's mountains, plains, wind and winters affect how people live and work; Week 17 state project: choose Wyoming.

    8. In Wyoming

      Other (computer science, by the end of Grade 5): Wyoming has separate Grade 3-5 computer science standards, to be in use by 2026-27, such as discussing real-world cybersecurity problems and protecting personal information (5.NI.C.01). Third Grade has no computer science strand.

      Suggested swap in Third Grade

      Science Week 14 or 23 (flex week): spend two days on online safety, strong passwords and keeping personal information private.

    Grade 3 public-school test
