Math

Oklahoma Academic Standards for Mathematics (OAS-M, 2022)

State's own standards · adopted 2022

Oklahoma writes its own standards, with codes like 3.N.2.2. Grade 3 goes further than Common Core in place value and in adding and subtracting (to 100,000) and adds money, 3-D shapes, angle types and thermometers. Equivalent fractions, classifying quadrilaterals, and liquid volume and mass wait until Grade 4, and time is read to five minutes.

Official standards

English Language Arts

Oklahoma Academic Standards for English Language Arts (2021)

State's own standards · adopted 2021

Oklahoma's own ELA standards, tested since spring 2024. Grade 3 includes print and cursive (3.2.PC), fact and opinion (3.3.R.6) and literary devices such as personification and hyperbole (3.3.R.4). Some grammar that Third Grade teaches this year, such as complex sentences and subject-verb agreement, is listed in Oklahoma's Grades 4 and 5.

Official standards

Science

Oklahoma Academic Standards for Science (OAS-S)

Based on the national science framework · adopted 2026

The state lists a 2020 version and a 2026 update side by side and does not say which is required in 2026-27. Both have the same 15 Grade 3 standards, which match the national science standards and are written with periods (3.PS2.1). The 2026 document adds three Grades 3-5 engineering design standards (G35.ETS1.1 to G35.ETS1.3).

Official standards

Social Studies

Oklahoma Academic Standards for Social Studies (2026)

State's own standards

Grade 3 is Oklahoma Studies: civics, history, geography and economics through the state, including American Indian Nations, statehood, state symbols and state and Tribal government. The state's page links the 2026 standards (codes like 3.C.3.2), but it has not said which school year they become required, and a formal review of them has begun. The 2019 standards number Grade 3 as 3.1.1 to 3.4.3.

Grade 3 differences

1. In Oklahoma

   Math: read, write and compare whole numbers up to 100,000, round to the nearest thousand and beyond, and add and subtract numbers up to five digits (3.N.1.1, 3.N.1.5, 3.N.2.3). Common Core Grade 3 works within 1,000.

   Suggested swap in Third Grade

   Math Week 1 (place value and rounding): extend one or two days to numbers up to 100,000 on a place-value chart. Math Weeks 2-3 (add and subtract within 1,000): finish each week with a few four- and five-digit problems.

2. In Oklahoma

   Math: multiply a two-digit number by a one-digit number (3.N.2.8). Third Grade multiplies within 100 and by multiples of 10.

   Suggested swap in Third Grade

   Math Week 16 (patterns, multiplying by multiples of 10): add two days of problems such as 4 x 23, drawn as an area model split into tens and ones.

3. In Oklahoma

   Math: count coins up to one dollar and add and subtract bills up to twenty dollars (3.N.4.1, 3.N.4.2). Common Core places money in Grade 2.

   Suggested swap in Third Grade

   Math Week 32 (flex week): add coin counting to $1, making change, and bill problems to $20.

4. In Oklahoma

   Math: sort 3-D shapes, build figures from unit cubes, and classify angles as acute, right, obtuse and straight (3.GM.1.1-1.3); read an analog thermometer in Fahrenheit and Celsius (3.GM.2.7).

   Suggested swap in Third Grade

   Math Week 34 (quadrilaterals): add angle sorting (acute, right, obtuse, straight) and a cube-building day; in Science Week 19 (weather tools), read the thermometer in both °F and °C.

5. In Oklahoma

   Social studies: the whole Grade 3 year is Oklahoma Studies in the 2026 standards (3.C.1.1 to 3.C.4.3), including the state's American Indian Nations, forced removals, statehood, the Oklahoma Constitution, state symbols (3.C.1.3) and notable Oklahomans (3.C.3.3).

   Suggested swap in Third Grade

   Social Studies Week 17 (state project): choose Oklahoma and include its symbols and notable Oklahomans; use Weeks 6, 8 and 12 (Native peoples; how our community began; Native nations) for Oklahoma's tribal nations and history, and Weeks 19-20 (local government; three branches) for state and Tribal government.

6. In Oklahoma

   ELA: form words correctly in print and cursive (3.2.PC). Common Core has no cursive standard.

   Suggested swap in Third Grade

   ELA Week 1 onward (weekly word study): add 10 minutes of cursive practice two or three days a week.

7. In Oklahoma

   ELA: find personification, hyperbole, simile, alliteration and onomatopoeia (3.3.R.4), and tell fact from opinion in informational text (3.3.R.6).

   Suggested swap in Third Grade

   ELA Week 26 (figurative language): add personification, hyperbole, alliteration and onomatopoeia to the similes and metaphors. ELA Week 7 (main idea): sort sentences from an article into facts and opinions.

8. In Oklahoma

   Math: Oklahoma places some of Third Grade's topics in Grade 4: equivalent fractions (4.N.3.1), liquid volume and mass (4.GM.2.7), classifying quadrilaterals (4.GM.1.2) and measuring to the quarter inch (4.GM.2.4).

   Suggested swap in Third Grade

   Math Weeks 21, 26 and 34 (equivalent fractions; mass and liquid volume; quadrilaterals) and Week 24 (measuring to half and quarter inch): teach them as written. They go beyond Oklahoma's Grade 3 list and prepare your child for Grade 4.

Grade 3 public-school test

Oklahoma School Testing Program (OSTP), Grade 3 ELA and mathematics

Oklahoma law does not require homeschoolers to register; the state's homeschool page says a standardized test is used if a child later enrolls in public school.
