Second Grade is built on the national frameworks that most state standards are based on or closely resemble: the Common Core State Standards for math and English language arts, the national K-12 science framework (the Next Generation Science Standards*), and the C3 Framework for social studies. Every lesson lists the standard it teaches.
Oklahoma Academic Standards for Mathematics (OAS-M, 2022)
The state's own standardsAdopted 2022
Oklahoma writes its own standards (it left Common Core in 2014). Strands: Number and Operations, Algebraic Reasoning and Algebra, Geometry and Measurement, Data and Probability. Tested since spring 2024.
Official standards (opens in a new tab)Oklahoma Academic Standards for English Language Arts (2021)
The state's own standardsAdopted 2021
Oklahoma's own ELA standards, tested since spring 2024; they include research and multimodal literacy strands at every grade.
Official standards (opens in a new tab)Oklahoma Academic Standards for Science (OAS-S)
Based on the national science framework, with the state's own changes
The state lists both the 2020 standards and an updated 2026 version; the exact year the update took effect was not confirmed. Grade 2 expectations follow the same list as the Next Generation Science Standards* Grade 2.
Official standards (opens in a new tab)Oklahoma Academic Standards for Social Studies (2026)
The state's own standards
The state lists the 2026 standards as current, but check timing: the 2025 standards were struck down by the Oklahoma Supreme Court, and the 2026 set was approved by the State Board in March 2026. Grade 2 covers civics, history, geography and economics, including local, state, national and Tribal governments.
Official standards (opens in a new tab)Math: tell time to the quarter hour (2.GM.3.2). Common Core Grade 2 asks for the nearest five minutes.
CoveredCovered in Week 23, where your child reads and sets times such as 1:15, 2:30 and 9:45.
Math: extend increasing and decreasing number patterns (2.A.1.1). Common Core has no Grade 2 pattern standard.
Partly coveredWeek 4 finds skip-counting patterns and Week 10 counts back by 10s. Add a 10-minute game: write patterns such as 5, 8, 11, __ and 50, 45, 40, __ and have your child extend each and say the rule.
Math: fair sharing into halves, thirds and fourths using length, set and area models (2.N.3.2). Common Core Grade 2 only splits shapes.
Partly coveredWeek 29 shares shapes, a paper strip and food into halves, thirds and fourths. Add a 10-minute set model: share 12 beans fairly between 2, 3 and 4 people.
ELA: find similes, alliteration and onomatopoeia (2.3.R.4). Common Core introduces similes in Grade 4.
Partly coveredWeek 13 teaches alliteration in poems. Add 10 minutes to find similes ('as fast as a cheetah') and sound words such as buzz and pop in a picture book.
