NYS 4th grade math is the year fractions go from 'introduce' to 'operate with' — and the second of three no-calculator grades, with multi-digit multiplication and long division coming in by hand.
Grade 4 NYS Math is the year fractions stop being a peek-ahead topic and become the central content of the test. Under NGLS, fourth graders work with fraction equivalence (NY-4.NF.1), comparing fractions with unlike denominators (4.NF.2), adding and subtracting fractions with like denominators (4.NF.3), and multiplying a fraction by a whole number (4.NF.4). It is also the year factors and multiples enter (4.OA.4 — prime, composite, factor pairs to 100), multi-digit multiplication moves into 4-digit × 1-digit and 2-digit × 2-digit (4.NBT.5), and the long-division algorithm appears for the first time (4.NBT.6). Calculators are still prohibited — Grade 4 is the second of three no-calculator NYS Math grades.
59% of New York fourth-graders scored Level 3 or higher on the 2024-25 NYS Math test — up just 1 percentage point from 58% the year before, the smallest YoY change of any grade. Read this as Grade 4 holding steady while the rest of the math sequence saw bigger swings. Grade 4 also introduces angle measurement with a protractor (4.MD.5-7), the first appearance of a measurement tool besides the ruler. On CBT, the protractor is a click-and-drag on-screen tool that confuses kids who've only used a plastic one in class.
Spring 2026 is the first year of universal CBT on NWEA — every Grades 3-8 test is now computer-based. For Grade 4, that means typing constructed-response work into the equation editor and using the on-screen protractor for angle items. Thirty minutes of practice on the NYSED Question Sampler removes the digital learning curve.
NYS uses 4 performance levels: Level 1 (below standard), Level 2 (partially proficient), Level 3 (proficient), Level 4 (excels). Level 3 or higher is the federal 'on grade level' target.
Spring 2026 is the first year of universal computer-based testing across every NYS Grades 3-8 test. NWEA is the statewide CBT vendor. New digital item types include drag-and-drop, hot text, multi-select, inline choice, dynamic graphing, and (for Math) the equation editor. Paper administration is available only as an IEP/504 accommodation. Free practice on the NYSED Question Sampler (nysed.gov/state-assessment/question-sampler) and CBTSupport.nysed.gov.
Up from 58% in 2023-24 (+1 ppt) — smallest YoY change of any grade. Statewide Math aggregate is 55%; Grade 4 sits 4 ppt above it.

NY-4 math under NGLS shifts the heaviest weight toward fractions while keeping operations & algebraic thinking strong. Multi-digit multiplication and the long-division algorithm enter Numbers & Operations in Base Ten. Measurement & Data adds angle measurement with a protractor — the first measurement-tool item beyond the ruler. Geometry covers classifying triangles and quadrilaterals by lines and angles. Calculators are prohibited across both sessions.
| Reporting Category | % of Test | What's Tested |
|---|---|---|
| Operations & Algebraic Thinking (NY-4.OA) | ~20-25% | Multi-step word problems with four operations, factor pairs and multiples to 100, prime and composite numbers, multiplicative comparison, generating and analyzing number/shape patterns. |
| Numbers & Operations — Fractions (NY-4.NF) | ~25-30% (heaviest cluster) | Fraction equivalence (4.NF.1), comparing fractions with unlike denominators (4.NF.2), adding/subtracting fractions with like denominators (4.NF.3), multiplying a fraction by a whole number (4.NF.4), and fraction-decimal equivalence with tenths and hundredths (4.NF.5-6). Heaviest single domain at Grade 4. |
| Numbers & Operations in Base Ten (NY-4.NBT) | ~20-25% | Place value to 1 million, multi-digit multiplication (4-digit × 1-digit and 2-digit × 2-digit), long division (4-digit ÷ 1-digit) — first year of the long-division algorithm — rounding multi-digit whole numbers. |
| Measurement & Data (NY-4.MD) | ~15-20% | Unit conversions within measurement systems (km to m, hours to minutes), area and perimeter word problems, line plots involving fractions of a unit, angle measurement with a protractor (4.MD.5-7, the first year a protractor appears). |
| Geometry (NY-4.G) | ~10-15% | Drawing and identifying lines, line segments, rays, angles (right/acute/obtuse), parallel and perpendicular lines, classifying triangles and quadrilaterals by lines and angles, identifying line symmetry in two-dimensional figures. |
Long division, ten minutes daily from January. NGLS NY-4.NBT.6 expects fluency with 4-digit-by-1-digit long division by year-end, and most fourth-graders need repetition to make the algorithm automatic. Once it's automatic, it stops eating brain space, freeing focus for the harder word problems where 3-credit points actually live. Khan Academy and the NYSED-released items are both good practice sources.
Fraction-decimal equivalence is the highest-leverage Grade 4 skill that isn't long division. If your child internalizes that 1/4 = 0.25 = 25%, they're set up for Grade 5 decimal operations and Grade 6 percent problems. If not, this is the year to lock it in. Use real-world contexts — quarters in a dollar, 25% off prices, batting averages, sports stats.
Practice the on-screen protractor before test day. The angle-measurement items at Grade 4 (4.MD.5-7) introduce the protractor for the first time, and on CBT it's a click-and-drag tool that behaves differently from a plastic protractor in class. The NYSED Question Sampler includes protractor practice — fifteen minutes there prevents test-day frustration.
Drill the 'show your work' habit on 3-credit items. The 3-credit constructed-response item debuts at Grade 4 and is the single biggest source of lost points. A correct numeric answer with no work shown earns 1 of 3 points; a partially-correct answer with labeled steps can earn 2 of 3. Train your child to use bullet points, drawings, equation chains, and 'First I... then I...' narration on every constructed-response item.
Use the NYSED released items as practice. NYSED releases 75% of items each year on nysedregents.org/ei/ei-math.html — including all constructed-response items with sample student responses and scoring notes. Reading a 3-credit response next to a 1-credit response teaches your child what 'good' looks like faster than any explanation. This is free, official material that competitor prep sites mostly paywall.
Five domains under NGLS. Operations & Algebraic Thinking (multi-step word problems, factors, primes), Numbers & Operations — Fractions (equivalence, comparing, addition/subtraction with like denominators, multiplying a fraction by a whole number, fraction-decimal equivalence with tenths/hundredths — the heaviest single cluster), Numbers & Operations in Base Ten (multi-digit multiplication, long division, place value to 1 million), Measurement & Data (unit conversions, area/perimeter, angle measurement with a protractor), and Geometry (lines, angles, classifying triangles and quadrilaterals).
Yes — Grade 4 is the heaviest fraction-focus year before middle school. NY-4.NF.1 through 4.NF.7 covers fraction equivalence, comparing fractions with unlike denominators, adding and subtracting fractions with like denominators, multiplying a fraction by a whole number, and fraction-decimal equivalence with tenths and hundredths. Fractions carry roughly 25-30% of the core — the largest single domain weight at Grade 4. Fraction-decimal equivalence (knowing 1/4 = 0.25) is one of the most-missed standards nationally.
Multiple, with the 3-credit items debuting at Grade 4. Across both sessions, expect several 1-credit short constructed-response items, several 2-credit items, and 3-4 3-credit items (the 3-credit items mostly appear in Session 2). The 3-credit rubric rewards correct answer + correct strategy + clear mathematical communication. A correct numeric answer with no work shown can score only 1 of 3 points.
No. Grade 4 NYS Math prohibits calculators on every session — the second of three no-calculator NYS Math grades (3, 4, 5). NGLS test design states explicitly that calculators are not allowed at Grades 3, 4, and 5. Calculators first appear at Grade 6 (Session 2 only). All multi-digit multiplication, long division, and fraction operations are computed by hand.
Level 3 or higher — 'proficient' — is the federal on-grade-level target. NYS uses four levels: Level 1 (below standard), Level 2 (partially proficient), Level 3 (proficient), Level 4 (excels). Scale-score Level 3 cut points are set per year by NYSED equating. 59% of NY 4th graders scored Level 3+ on the 2024-25 test, up just 1 ppt from 58% the year before.
1-credit items (multiple-choice and short selected-response) are machine-scored. 2- and 3-credit constructed-response items are hand-scored by trained NY educators using NYSED rubrics — the 3-credit rubric rewards correct answer, correct strategy, and clear mathematical communication. Raw points convert to a scale score and a performance level (1-4). Two raters score each constructed-response item; large disagreements go to a third rater.
Three big differences. (1) Fractions become operational, not just introductory — Grade 4 students add, subtract, and multiply with fractions, where Grade 3 only compared and placed them on a number line. (2) Multi-digit multiplication and the long-division algorithm enter Numbers & Operations in Base Ten — both are by hand because calculators are still prohibited. (3) The 3-credit constructed-response item debuts at Grade 4 in Session 2. Otherwise the test structure (two untimed sessions, CBT on NWEA, no calculator) is identical to Grade 3.
Two sessions across two consecutive school days, untimed (since 2016). Schools commonly plan 70-100 minutes for each session. Most fourth-graders finish each session in 70-90 minutes — the longer constructed-response items add time versus Grade 3. As with every NYS test, no clock cuts a student off who is still working productively within the school day.
