Fourth grade is Ohio's strongest math year — 70% of fourth graders were proficient in 2025 — but multi-digit operations and deeper fractions are where the gap opens for the other 30%.

A factory in Akron produces 78 tires per hour. How many tires does it produce in 24 hours?
Grade 4 is the high-water mark for Ohio math: at 70% proficient in 2025, it's the strongest-performing math grade in the state. That's a genuinely encouraging number — but it still means roughly three in ten fourth graders are below grade level, and the content is a real step up from grade 3.
The test measures Ohio's Learning Standards, with grade-4 reporting categories of Multiplication & Division, Fractions, Geometry, and Modeling & Reasoning. The year's biggest jumps are multi-digit multiplication and long division, and a much deeper treatment of fractions — equivalent fractions, comparing fractions, and adding and subtracting fractions with like denominators.
In 2025, 70% of Ohio fourth graders reached Proficient or above (scale 700+ — "on grade level"). It's the best year to build math confidence before the grade-5 slide.
Ohio's State Tests are online, two-part tests on Cambium (paper as an accommodation). NO calculator is allowed at grade 4 — Ohio keeps calculators out of grades 3-5 math entirely.
Proficient + Accomplished + Advanced (scale 700+ = on grade level) — Ohio's strongest math grade. Basic and Limited are below grade level.

Grade 4 math on the OST is organized into Ohio's Learning Standards reporting categories, with Multiplication & Division and Fractions carrying the year's core difficulty. Exact per-category weights are in ODEW's blueprints and not restated here to avoid an unverified figure.
| Reporting Category | What's Tested |
|---|---|
| Multiplication & Division | Multi-digit multiplication and long division, plus multi-step word problems using the four operations. The heaviest strand at grade 4. |
| Fractions | Equivalent fractions, comparing fractions, and adding and subtracting fractions with like denominators — the year fractions deepen significantly. |
| Geometry | Lines, angles, and symmetry, and classifying two-dimensional figures by their properties. |
| Modeling & Reasoning | Applying math to real problems and explaining reasoning — present on every Ohio math test. |
Drill multi-digit multiplication and long division — the biggest new skills and the most common point-losers at grade 4.
Go deep on fractions — equivalence and comparison. Grade 4 is where fractions either click or become a lasting gap.
Use this strong year to build confidence before grade 5, where Ohio math proficiency drops from 70% to 57%.
Practice by hand. Grade 4 is calculator-free, so fluency without a device is what's tested.
Built on Ohio's Learning Standards: Multiplication & Division (multi-digit multiplication, long division — the core), Fractions (equivalent fractions, comparing, adding/subtracting with like denominators), Geometry (lines, angles, symmetry, 2D figures), and Modeling & Reasoning.
No. Ohio prohibits calculators on grades 3-5 math. By-hand fluency with multi-digit multiplication and long division is what the test rewards.
In Spring 2025, 70% of Ohio fourth graders scored Proficient or above — the strongest math grade in the state, though about three in ten were still below grade level.
'On grade level' means Proficient or above (scale score 700+). Basic and Limited are below grade level. Grades 4-8 OSTs are not a promotion gate.
