CCSS↔TEKS crosswalk

STAAR follows the Texas Essential Knowledge and Skills (TEKS). Our missions are CCSS-aligned, and the elementary math TEKS overlap heavily with Common Core — the underlying math is the same. Each topic below shows both the TEKS readiness/supporting standard and the matching CCSS code so Texas families know exactly what's covered.

  1. 01

    Multi-Digit Multiplication

    TEKS 4.4D (Readiness) CCSS 4.NBT.B.5

    Multiply up to a four-digit number by a one-digit number, and two two-digit numbers — using arrays, area models, and the standard algorithm.

    Key terms: Partial Product · Area Model · Standard Algorithm · Place Value

  2. 02

    Long Division & Remainders

    TEKS 4.4F (Readiness) CCSS 4.NBT.B.6

    Divide whole numbers up to four digits by a one-digit divisor using equations, rectangular arrays, and area models. Interpret remainders in context.

    Key terms: Dividend · Divisor · Quotient · Remainder · Place Value

  3. 03

    Equivalent Fractions & Comparing

    TEKS 4.3D (Readiness) CCSS 4.NF.A.1 / 4.NF.A.2

    Generate equivalent fractions and compare two fractions with different numerators and different denominators using benchmark fractions.

    Key terms: Common Denominator · Benchmark · Cross-Multiply · Equivalent

  4. 04

    Adding & Subtracting Fractions

    TEKS 4.3E (Readiness) CCSS 4.NF.B.3

    Add and subtract fractions with like denominators referring to the same whole, including mixed numbers and word problems.

    Key terms: Like Denominator · Mixed Number · Improper Fraction · Whole

  5. 05

    Decimal Notation & Place Value

    TEKS 4.2G / 4.2H (Supporting) CCSS 4.NF.C.6 / 4.NF.C.7

    Use decimal notation for fractions with denominators 10 or 100. Compare decimals to hundredths using place-value reasoning.

    Key terms: Tenths · Hundredths · Decimal Point · Place Value

    Angle Measurement

    TEKS 4.7C / 4.7D (Supporting) CCSS 4.MD.C.5 / 4.MD.C.6

    Recognize angles as geometric shapes formed by two rays sharing an endpoint. Measure and sketch angles in whole-number degrees using a protractor.

    Key terms: Degree · Protractor · Vertex · Ray · Right Angle

STAAR Grade 4 Math — FAQ

What's tested, how the CCSS↔TEKS overlap works, and how to print STAAR Grade 4 worksheets.

What does STAAR Grade 4 math cover?

STAAR Grade 4 math focuses on multi-digit multiplication and long division, fraction equivalence and addition with like denominators, decimal notation to hundredths, and angle measurement. The six readiness/supporting standards above cover the highest-weighted reporting categories.

STAAR is TEKS-based — how do CCSS-aligned missions help?

For Grade 4, TEKS and Common Core overlap on every major strand. Both standards teach the area-model for multi-digit multiplication, equivalent fractions through partitioning, decimal notation as a special case of fractions, and angle measurement using a protractor. Each topic above shows both the TEKS standard and the matching CCSS code.

Are the printable STAAR Grade 4 worksheets free?

Yes. Open the Grade 4 PDF Handbook below and use your browser's "Print → Save as PDF" on any topic guide to generate a free printable STAAR-aligned worksheet. No login or subscription required.

Which STAAR Grade 4 standard decays fastest in summer?

Fraction equivalence and the area model for multi-digit multiplication are the highest-decay STAAR Grade 4 skills. If your child is heading into 5th grade, prioritize TEKS 4.3D (equivalent fractions) and 4.4D (multi-digit multiplication) for summer review — both are foundational for STAAR Grade 5 decimal operations and unlike-denominator addition.

Is Inquiry AI Common Core aligned?

Yes. Every mission, handbook page, and topic hub is mapped to a specific CCSS code (visible in the page header). The curriculum follows the CCSS coherence map: Grade 1 number sense → Grade 3 multiplicative thinking → Grade 6 ratio reasoning, with each grade building strictly on the prior year's foundations.

What is inquiry-based learning, and how does Inquiry AI apply it?

Inquiry-based learning starts with a question, not a formula — students explore, hypothesize, and verify before being told the rule. In Inquiry AI, every mission opens with a "Discovery" step (manipulate the model), then "Abstraction" (write the equation), then "Reflect" (apply to a new case). The procedure is never given upfront; learners derive it from their own observations.

How is Guided Discovery Learning different from "just letting kids figure it out"?

Pure discovery is inefficient — kids hit a wall and quit. Guided Discovery scaffolds the path: a careful sequence of questions, models, and adaptive hints leads the learner toward the insight without revealing it. Inquiry AI's hint system fires automatically after ~15s of hesitation or on the first mistake, escalating from a Socratic nudge to a worked example only when needed. Mistakes are diagnosed via "misconception keys" so the hint matches the actual wrong-thinking pattern.

What does it mean for a math platform to be "Socratic"?

Socratic teaching answers a question with a better question. Instead of "the answer is 12", the system asks "if you had 3 groups of 4, how could you skip-count?" The goal is to externalize the learner's reasoning so they hear themselves think. Every Inquiry AI hint follows this pattern: nudge → reframe → analogy → only then a worked example, in that order.

What is the Concrete-Pictorial-Abstract (C-P-A) approach?

C-P-A is the Singapore Math sequence proven to deepen number sense: first manipulate physical objects (Concrete), then draw pictures of them (Pictorial), and only then write equations (Abstract). Inquiry AI structures every mission as exactly these three steps — a manipulative, a picture/grid model, and finally the equation. Skipping straight to symbols is the #1 cause of math anxiety; the platform refuses to do it.

Why does Inquiry AI let kids "struggle" before showing the answer?

Research on "productive struggle" shows that 20–60 seconds of focused effort BEFORE help dramatically improves long-term retention — the brain encodes the strategy more deeply. Inquiry AI's hint timing is calibrated to this window: short enough to prevent frustration, long enough to lock in the learning. Parents can adjust the threshold in settings if a learner needs faster scaffolding.
