ILEARN 4th grade math is Indiana's triple-test grade (Math + ELA + Science all in the same spring window) and the year long division, multi-digit multiplication, fractions with like denominators, and the on-screen protractor all enter the test at once — still with zero calculator access.
Grade 4 ILEARN Math is the year your child takes three different ILEARN tests in the same spring window — Math, ELA, and Science. (Indiana tests science at Grade 4 and Grade 6 only — most states test it at Grade 5, which catches parents off guard.) The math test covers multi-digit multiplication (4-digit by 1-digit, 2-digit by 2-digit), long division, fractions with like denominators and the first multiplication of a fraction by a whole number, decimal notation for fractions with denominators 10 and 100, angle measurement with a protractor (in degrees), and line symmetry. Indiana Academic Standards organize Grade 4 into six strands; the ILEARN blueprint reports them in three combined categories.
The 2025 results were strong. Grade 4 Math grew +5.5 ppt versus the 2021 baseline — one of the better growth trajectories in elementary math, behind only the +6.7 ppt gains at Grades 6 and 8. The per-grade absolute proficiency rate for 2025 was not isolated in the IDOE July 16, 2025 press release; secondary aggregators report it around 49.2% but the authoritative source is the IDOE EDC dashboard (December publish). Statewide ILEARN Math across grades 3-8 was 42.1% At-or-Above Proficiency in 2025 (+1.2 ppt YoY), so Grade 4 sits meaningfully above the state aggregate.
What's structurally important: Grade 4 is the second non-calculator math year in a row (calculators don't enter ILEARN Math until Grade 7). The combination of long division + multi-digit multiplication + fraction operations + angle measurement, all computed by hand, is what makes Grade 4 the procedural-fluency year — get the algorithms automatic now and the conceptual problems at Grade 5 get easier.
ILEARN reports 4 performance levels: Below Proficiency, Approaching Proficiency, At Proficiency, and Above Proficiency. IDOE counts students who score 'At' or 'Above' as on track for college and career readiness; the bottom two levels are 'not on track.' Per-grade scale-score cut points are published in the IDOE Cut Scores PDF (in.gov/doe/files/ILEARN-Cut-Scores-2.pdf) — they are not the same number across grades or subjects.
ILEARN Math and ELA are Computer-Adaptive Tests (CAT) delivered on the Cambium TDS platform at indiana.portal.cambiumast.com. Items adjust to student performance — harder if a child gets one right, easier if wrong. The test is untimed; districts typically schedule it across multiple shorter sessions within the April 13 – May 8, 2026 online window.
New for 2025-26, Indiana also runs three mandatory ILEARN Checkpoints (fall, winter, spring) in Math and ELA only. Each Checkpoint is 20-25 questions, CAT, untimed, and zero-stakes — Checkpoints do NOT count toward your child's proficiency level or the school's accountability score. They exist purely to inform instruction between now and the April-May summative.
Strong growth trajectory — one of the better elementary math gains in 2025, behind only Grades 6 and 8 (+6.7 ppt each). Statewide ILEARN Math aggregate 2025 was 42.1% At/Above. The Grade 4 absolute % was not isolated in the IDOE July 16 release; secondary sources cite ~49.2% pending IDOE EDC dashboard publication in December.

Grade 4 ILEARN Math under Indiana Academic Standards reports three combined categories. Computation is the heaviest (multi-digit multiplication, long division, fraction operations). Algebraic Thinking and Data Analysis is combined (multi-step word problems, line plots with fractional units). Geometry and Measurement covers angles, line symmetry, and area/perimeter formulas. Number Sense fills out the remainder. Every item is non-calculator.
| Reporting Category | % of Test | What's Tested |
|---|---|---|
| Computation | 23-28% (11-13 operational items) | Multi-digit multiplication using the standard algorithm (4-digit by 1-digit and 2-digit by 2-digit); long division (4-digit by 1-digit); add and subtract fractions with like denominators; multiply a fraction by a whole number; decimal computation with tenths and hundredths. Heaviest cluster on Grade 4 ILEARN Math. |
| Algebraic Thinking and Data Analysis | 19-24% (9-11 items) | Multi-step word problems using all four operations; identify arithmetic patterns; line plots with fractional units (halves, quarters, eighths); analyze data sets and answer comparison questions. |
| Geometry and Measurement | 19-24% | Lines, line segments, rays, angles (right, acute, obtuse); classify two-dimensional figures by line and angle properties; line symmetry; convert within measurement systems (km to m to cm); area and perimeter formulas; angle measurement with a protractor in degrees (the on-screen protractor appears for the first time on ILEARN here). |
| Number Sense | remainder | Multi-digit place value through one million; decimal notation for fractions with denominators 10 and 100; compare fractions with different numerators and denominators using benchmarks; multiples and factors; prime and composite numbers. |
Long division and multi-digit multiplication, ten minutes daily. IAS expects fluency with 4-digit by 1-digit long division and 2-digit by 2-digit multiplication by year-end. Most fourth-graders need repetition to make the algorithms automatic — and once they're automatic, they stop eating brain space, freeing focus for the harder word problems where constructed-response points actually live.
Decimal notation for tenths and hundredths is the highest-leverage Grade 4 skill that isn't long division. If your child understands that 7/10 = 0.7 and 35/100 = 0.35, they're set up for Grade 5 decimal operations and Grade 6 percent. Use real-world examples — money, baseball batting averages, percentages off in stores.
Practice with the on-screen protractor on the Cambium portal. The digital tool is a click-and-drag version that confuses kids who have only used a plastic classroom protractor. Five minutes of practice on indiana.portal.cambiumast.com/ilearn.html prevents the test-day surprise.
Plan for three tests in one window. Grade 4 ILEARN spring 2026 = Math + ELA + Science, all between April 13 and May 8. Your child will take them across multiple sittings. Help them budget energy — Indiana tests are untimed, so a tired kid can ask for a break instead of pushing through.
Don't substitute generic Common Core workbooks for Indiana-specific materials. Indiana withdrew from Common Core in 2014. The IAS code labels (4.NS, 4.C, 4.AT, 4.G, 4.M, 4.DA) are different even where content overlaps. Use materials labeled Indiana Academic Standards or ILEARN specifically.
Multi-digit multiplication using the standard algorithm (4-digit by 1-digit and 2-digit by 2-digit), long division, fractions (add/subtract with like denominators, multiply a fraction by a whole number), decimal notation for tenths and hundredths, area and perimeter formulas, angle measurement with a protractor, line symmetry, multiples and factors, and multi-step word problems using all four operations. Computation is the heaviest cluster at 23-28% of the test.
No. Grade 4 ILEARN Math is non-calculator throughout — there is no calculator-allowed segment. Calculators do not enter ILEARN Math until the calculator-allowed segments at Grade 7. Practice without a calculator at home so the test environment is not a surprise.
It is the first ILEARN year with both multi-digit operations AND fraction operations layered together, which is why families call it a bridge year. The Algorithms (long division, 2-digit by 2-digit multiplication) and the fraction operations (add/subtract like denominators, multiply fraction by whole number) hit in the same spring window. But Indiana's Grade 4 Math results have grown +5.5 ppt since 2021 — the bridge has gotten easier with stronger elementary instruction.
Start with the official Cambium Indiana Assessment Portal at indiana.portal.cambiumast.com/ilearn.html — the practice scripts use the exact same engine and item types as the real test. Third Space Learning's Grade 4 Indiana practice tests, Lumos Learning's free sample sets, and Tutorified's ILEARN Grade 4 practice PDFs all align with IAS. Avoid generic 'Common Core 4th grade math' workbooks — Indiana withdrew from Common Core in 2014, and the IAS code labels are different.
Between April 13 and May 8, 2026 for the online administration. Paper (accommodation only) is open through May 15, 2026. Your fourth-grader will also take ILEARN ELA and ILEARN Science in the same window — three different tests across multiple sittings.
Indiana uses four performance levels: Below Proficiency, Approaching Proficiency, At Proficiency, Above Proficiency. 'At Proficiency' or higher counts as on track for college and career readiness per IDOE. The numeric scale-score cut points are in the IDOE Cut Scores PDF (in.gov/doe/files/ILEARN-Cut-Scores-2.pdf) — they are different at each grade and should not be invented.
Yes. Indiana tests ILEARN Science at Grade 4 and Grade 6 only — Grade 4 is the elementary science year. Most other states test elementary science at Grade 5, so Indiana parents often Google 'Indiana 5th grade science test' looking for one that doesn't exist. Your fourth-grader takes three ILEARN tests this spring: Math, ELA, and Science.
Grade 4 introduces angle measurement in degrees, and the Cambium TDS platform has a built-in on-screen protractor — a click-and-drag tool, not a physical one. Many fourth-graders have only used a plastic classroom protractor and find the digital version awkward the first time they see it. Five to ten minutes of practice with the on-screen version on the Cambium portal (indiana.portal.cambiumast.com/ilearn.html) prevents test-day frustration.
